Is a mixture always a chemical combining of substances?
Any particular isolated sample of a mixture has a definite chemical composition, but the general idea of a mixture, even of the same materials, implies variability in possible chemical composition.
What do mixture and substances have alike?
Both are composed from chemical elements.
What is the chemical symbol for opium?
There is no chemical symbol for opium. It is a mixture. Only pure substances have chemical symbols.
What happens to substances in a chemical change?
It creates a new mixture and is irreversible.
Why do substances in a mixture keep their identities?
Substances in a mixture retain their identities because the individual components do not chemically react with each other, but rather exist together physically. The properties and identities of the substances remain unchanged in a mixture.
Is A mixture is a chemical combination of substances?
No. A mixture is a mechanical combination of substances. A chemical combination of two or more elements is a compound.
Ty added water to a mixture of two other substances. A short time later the observed that one substance had turned green and another had turned orange What might Ty infer?
Ty can infer that the two original substances in the mixture must have properties that react with water to produce the green and orange colors when exposed to it. This observation suggests a chemical reaction might have occurred between the substances and the water.
Is a mixture always a chemical combining of substances?
Any particular isolated sample of a mixture has a definite chemical composition, but the general idea of a mixture, even of the same materials, implies variability in possible chemical composition.
How are pure substances and mixtures different?
Both mixtures and pure substances have measurable and observable chemical properties and physical properties. A liquid mixture vaporizes over a temperature range; whereas, a pure substance boils at a fixed temperature.
How mixture relate to substance?
A mixture contain two or more substances (chemical compounds).
When two or more substances are mixed together without undergoing a chemical reaction it results in?
If you mix things together, you get a mixture.
What do mixture and substances have alike?
Both are composed from chemical elements.
What is a mixture of two or more substances?
A combination of two substances that do not chemically react can be a mixture or a solution.When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
What is the chemical symbol for opium?
There is no chemical symbol for opium. It is a mixture. Only pure substances have chemical symbols.
What happens to substances in a chemical change?
It creates a new mixture and is irreversible.
Is bread a chemical change?
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
Why do substances in a mixture keep their identities?
Substances in a mixture retain their identities because the individual components do not chemically react with each other, but rather exist together physically. The properties and identities of the substances remain unchanged in a mixture.
