What are word equations to describe a chemical change?
In a chemical change, reactants are transformed into products through the breaking and forming of chemical bonds. Word equations typically describe this transformation using the names of the reactants and products, such as "hydrogen peroxide (H2O2) + manganese dioxide (MnO2) → water (H2O) + oxygen (O2)."
Is melting ice example of chemical property?
No, melting ice is a physical change because it does not involve a change in the chemical composition of the substance. Chemical properties describe how a substance reacts with other substances to form new substances.
What do chemical equations describe?
Chemical equations describe the chemical reactions that occur between reactants to form products. They show the substances involved in the reaction and the ratio in which they combine.
What is the term for a shorthand representation using formulas and symbols to describe a chemical change?
I suppose that you think to a chemical equation.
Chemical change same as chemical reaction?
no because a chemical change is any process in which 1 or more substance is changed into 1 or more substances whereas a chemical reaction is a process that leads to a transformation of one set of chemical substances to another
What can be used to describe a chemical change?
A chemical equation can be used to describe a chemical change. For instance when iron combines with oxygen to form iron (III) oxide (rust), a chemical change has occurred. It can be written as a chemical formula: 4 Fe + 3 O2 --> 2 Fe2O3

Does cutting a strip of aluminum describe a chemical change?
Cutting is a physical process.

This is true.
What is the differences between chemical and physical change?
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
Is rusting a physical change of metal?
Chemical Yes. The metal is being converted to an oxide of that metal. Most would (correctly) describe this as a chemical change, but physics has a lot to do with how that happens.
What is a physical or chemical change that breaks rocks into fragments?
Weathering is the term used to describe the reduction in the size of a rock by chemical or physical means.
Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
