Does a compound retain its properties?
A compound does not retain the physical properties of its constituent elements. Because when two or more elements get combined chemically, they form a new compound with new chemical and physical properties depending on the nature of bonding in the compound.
Do compounds retain the properties of the elements that make them up?
In a compound the atoms/molecules) are (chemically physically) combined so that the elements that make up the compound (retain lose) their identities and ((do/do not) take on a new set of properties.
Do compounds keep or lose their original properties?
In a compound the (atoms/molecules) are (chemically physically) combined so that the elements that make up the compound (retain/lose) their identities and (do do not) take on a new set of properties.
Do compounds properties change?
The properties of compounds are different from the properties of the elements that form them—sometimes very different. That’s because elements in a compound combine and become an entirely different substance with its own unique properties. Do you put salt on your food? Table salt is the compound sodium chloride.
Is compound a property?
A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.
What parts keep their original properties?
Components are elements. Components keep their original properties. Components lose their original properties. Separated by physical means.
Can compounds have different properties than their elements?
Compound. A compound is a pure substance whose smallest unit is made up of atoms of two or more elements joined by chemical bonds. Compounds have different properties than the individual elements that make up the compound. Compounds can only be separated by chemical means.
Do elements and compounds have new properties or keep the old ones?
The elements in a compound do not always retain their original properties and cannot be separated by physical means. The combining of elements is facilitated by their valency. Valency is defined as the number of hydrogen atoms required that can combine with an atom of the element forming the compound.
Are properties of each substance in the mixture are changed or unchanged?
General Properties of Mixtures
The properties of mixtures are listed below. The components of a mixture each keep their original properties. The separation of components can be easily done. The proportion of the components is variable.
Do substances lose or retain their identities in a mixture?
In a mixture, the substances (lose/retain) their identities. In a mixture the substances involved (can/cannot) be separated by a simple physical process. In a compound the elements involved (can/cannot) be separated by a simple physical process because the elements are (physically combined chemically bonded).
Do compounds have characteristic physical properties?
Compounds have physical and chemical properties that help us identify them. A physical property is a characteristic that can be observed or measured. In this lesson, we looked at some of the more common physical properties of compounds, including color, odor, melting point and boiling point.
Do compounds have the same properties?
Compounds have NEITHER the same chemical properties NOR the same physical properties as their constituent elements.
Can a compound be broken down?
Compounds can be broken down into their constituent elements by chemical changes. A chemical change (that is, a chemical reaction) is one in which the organization of the atoms is altered.
How does the structure of polymers affect their properties?
Polymers consist of very long molecules that contain chains of carbon. They too are held together by very strong covalent bonds. There are greater intermolecular forces between the long chains compared with smaller simple molecules. This means that polymers have a higher melting point than many other organic molecules.
Why are the properties of different compounds so different from?
Answer. Compounds have different properties from the elements that make them. The atoms of different elements are held together in compounds by chemical bonds. Chemical bonds can hold atoms together in large networks or in small groups.
What determines the properties of a compound?
All of these properties are due to the chemical structure of the compound. The chemical structure includes the bonding angle, the type of bonds, the size of the molecule, and the interactions between molecules. Slight changes in the chemical structure can drastically affect the properties of the compound.
Do compounds have compositions that vary?
An element has a fixed composition because it contains only one type of atom. A compound always contains two or more elements in a fixed proportion. How do mixtures differ from pure substances? The properties of a mixture can vary because the composition of the mixture is not fixed.
Are mixtures physically or chemically combined?
A mixture is a physical combination of two or more substances where there is no chemical combination or reaction. Mixtures combine physically in no specific proportions. They just mix. Solids, liquids and gases can be combined to create a mixture.
What is the substance that dissolves the other substance in a solution?
A solution forms when one substance dissolves in another. The substance that dissolves is called the solute. The substance that dissolves it is called the solvent.
Which mixtures can you not distinguish the components?
In homogeneous mixtures, you can not distinguish each component with the naked eye. They have a uniform composition. For example sea water, air , and vinegar. Steel is a homogeneous mixture, however it is made from iron and carbon.
Do the different substances in a mixture keep their own properties?
A mixture is a combination of two or more substances in any proportions. The substances in a mixture do not combine chemically, so they retain their physical properties. A homogeneous mixture has the same composition throughout.
How do the properties of a compound with the properties of the element is made from?
A compound has a definite chemical composition and hence specific formula. A compound has chemical properties different from the properties of the elements it contains. Molecules are substances formed when two or more atoms are chemically joined (bonded).
Which of the following is not a property of mixture?
A mixture does not have a sharp melting or boiling point. It may be homogeneous or heterogeneous. Energy is neither given out nor absorbed in the preparation of a mixture. However, heat is taken in or given out in the preparation of a compound.
Why can properties of mixture vary?
The properties of a mixture can vary, because the composition of a mixture is not fixed. If amount one of substance in mixture is changed, the properties such system is also changed.
How properties of matter help you identify the changes that a substance went through?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
What happens to the substance in a mixture?
A mixture contains two or more substances (such as elements, compounds) combined together in varying proportions. Each component retains its own independent properties and has undergone no chemical reaction with any other substance in the mixture.
Would there be life if elements did not form compounds?
What would happen if the atoms of elements couldn’t join together to form molecules? There would be no such thing as water. The world would be very different if compounds didn’t exist. formed when sodium atoms join with chlorine atoms.
Do compounds separate when heated?
Heat is an energy source that can cause compounds to break down. This allows the compounds to split into smaller units.
Which compound can show existence?
A smallest part of the compound that can have the independence existence and that can retain all the properties of that compound is called as molecule. Ex: H2,Cl2.
Can an element be broken down into a simpler substance?
chemical element, also called element, any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed.
Is the smallest particle of an element that retains the properties of that element the building blocks of matter?
An atom is the smallest unit of matter that retains all of the chemical properties of an element.
What is a property of a substance?
Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. Properties that describe how a substance changes identity to produce a new substance are chemical properties.
What factors affect polymer properties?
The processing conditions which can affect the properties of the polymer include the temperature and pressure used during the polymerization, the solvent in which the polymer is polymerized, the types of monomer units used, the concentration of monomers in the reaction, the reagent which is used to initiate the …
Why do polymers have different properties?
Why do different polymers have different properties? Answer: They have different chemical compositions (different monomer units), different structures, different ways of being fabricated, etc.
How does the structure of molecules affect their properties?
The molecular structure affects the molecular properties because the shape of of a molecule has a lot to do with the polarity of the compound. Polar compounds tend to dissolve in polar compounds, have higher boiling and higher melting points and form solids or liquids.
Why compounds don’t have many of the properties of their elements?
The properties of compounds are different from the properties of the elements that form them—sometimes very different. That’s because elements in a compound combine and become an entirely different substance with its own unique properties.
Why are the properties of different compounds so different from each other explain with examples Class 7?
Each compound is formed by a different set of elements. 2. Even with the same set of elements, different compounds are formed by varying numbers of constituent atoms. Example: Just varying the number of carbon and oxygen atoms, we get carbon monoxide or CO (toxic gas) and carbon dioxide or CO2 (non-toxic gas).
What are cations and do they lose or gain electrons to form their charge?
Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
Is compound a property?
A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.
Do compounds have constant composition?
In any given chemical compound, the elements always combine in the same proportion with each other. This is the law of constant composition. The law of constant composition says that, in any particular chemical compound, all samples of that compound will be made up of the same elements in the same proportion or ratio.
Can ah * * * * * * * * * * mixture have variable composition justify giving an example?
Yes, homogenous mixture have a variable composition as the constituents are present in any ratio such as 1:2 or 1:3 etc.
Does compounds have fixed composition?
The composition of a compound is fixed, the constituents are present in fixed proportion by mass. A compound has definite formula.
Is salt a solvent or a solute?
For example, in a solution of salt in water, the solute is salt, and solvent is water. Solutions come in all phases, and the solvent and the solute do not have to be in the same phase to form a solution (such as salt and water).
Why do some things dissolve in water and others don t?
Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water. Oil contains molecules that are non-polar, thus they do not dissolve in water.
Can a solution have more than one solute?
A solution is a homogeneous mixture of two or more substances. The substance that is present in the largest amount is called the solvent and the one present in the smaller amount is called a solute. There can only be one solvent in a solution, but there can be many solutes.
Which mixture that can you still easily distinguish the components give the components?
A heterogeneous mixture is a mixture of two or more chemical substances (elements or compounds), where the different components can be visually distinguished and easily separated by physical means. Examples include: mixtures of sand and water. mixtures of sand and iron filings.
Can you easily distinguish each component Why?
Answer: there is 2 types of mixture: the heterogeneous mixture which you can easily distinguised it’s components because the solute is not fully dissolved and the homogeneous mixture or solution which you can’t easily distinguished it’s components because it’s solute is dissolved by the solvent.
