Do substances have different properties?
Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants.
Can two different substances have the same property?
Finding any matching densities will give you information about the possible identity of the unknown substance. However, it is possible for two different substances to have the same density.
What are all the properties 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.
Do substances keep properties?
In chemistry, a chemical substance is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components without breaking chemical bonds.
How can you say that one substance is different from other?
Different substances have different properties; density is one property that can be used to tell two substances apart. Density is a property that does not depend on the shape or size of an object.
What properties do both substances have in common?
Common Properties
Both mixtures and pure substances have weight, volume and color while solids also have shape and hardness or texture.
What makes one substance different from another?
The characteristics that enable us to distinguish one substance from another are called properties. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.
How can matter made of the same substances look different?
The molecules of the substance remain the same no matter what state they are in. Matter looks different and behaves differently when it changes from one state to another. All particles of matter are in constant random motion. Particles of liquid water have less energy and move slower than particles of water vapor.
Do elements and compounds have the same properties?
1 Answer. Compounds have NEITHER the same chemical properties NOR the same physical properties as their constituent elements.
Do substances lose their properties 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.
Do substances lose their physical characteristics 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).
What factors determine the physical properties of a substance?
- The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart.
- The attractive intermolecular forces between particles that tend to draw the particles together.
Is milk a pure substance?
Milk is not a pure substance, it is a colloidal mixture. Pure substances are either elements or compounds while a mixture is a combination of two or more products. Milk contains water, proteins, fat, solid, and hence it is not a pure substance.
On what factors do the properties of a substance depends?
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity.
How can knowing the properties of the different substances in a mixture be useful?
The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances.
Are a substance and a pure substance the same?
In everyday usage, a pure substance is a material that is free of impurities or contaminants. However, the definition of a pure substance is more narrow in chemistry. In chemistry, a pure substance has a constant chemical composition. No matter where you sample a substance, it is the same.
What is the similarities and differences between pure substances and mixture?
1. Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances. 2. A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties (i.e., boiling point and melting point).
What kind of properties can only be observed when a substance changes into a different substance?
Summary. Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
How are a substance and a solution similar?
Answer. Answer and Explanation: A substanceand solution are similar because asolution is a homogeneous blend of two or more elements and/or compounds. A substance is an element or a compound; therefore, asolution is a homogeneous combination of two or moresubstances.
Are all atoms the same?
Everything in this world are matter and comprises of atoms. But each and every atom is unique. They are not the same at all. Every atom consists of three basic units protons, neutrons, and electrons and these units determine the physical and chemical properties of an atom and matter.
What is the difference between substance and matter?
anything which occupies space and has mass is called matter. But the that has specific composition and chemical characteristics is substance.
What is the similarity between the compounds?

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 keep their original properties?
Each substance in a compound loses its original properties. Compounds are commonly found in nature. Solids, liquids, and gases can form compounds.
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.
Is seawater a pure substance?
Seawater is a mixture of many different substances. Some of these substances can be observed when the water in seawater evaporates and leaves behind salt. Water, H2O, is a pure substance, a compound made of hydrogen and oxygen.
Is an egg a pure substance?
Scrambled eggs contains many different chemical compounds, including water, various proteins from the egg, some fat that it has been cooked in, and possibly some milk (which is in itself a mixture). Therefore scrambled eggs are clearly a mixture.
What word describes different compounds which are found together but not combined chemically?
A mixture contains two or more different substances that are not chemically joined together. The different substances in a mixture can be elements and/or compounds. dome7w and 3 more users found this answer helpful.
How are compounds and mixtures similar?
They are made from the same types of molecules. Each molecule of a compound is made from two or more different kinds of atoms that are chemically bonded. Mixtures are made of two or more substances — elements or compounds — that are mixed physically but not chemically; they do not contain any atomic bonds.
