when 2 or more compounds react chemically to form a new compound then it is called chemical reaction chemical reaction whereas the quantity and no. chemical elements presents in chemical compound is called the chemical composition
A liquid is a compound or a mixture; the chemical composition is representative for this liquid.
energy released by the reaction or energy absorbed.
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
The amount of heat given off by the reaction
A reaction is considered chemical when bonds between atoms are broken and new bonds are formed, resulting in a change in the chemical composition of the substances involved. Physical changes, on the other hand, do not involve changes in the chemical composition of the substances.

reactant + reactant = product
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
Phase has nothing to do with chemical composition.
The amount of heat given off by the reaction
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials
The ash composition affects the amount of potassium hydroxide needed in a chemical reaction. Different ash compositions may require different amounts of potassium hydroxide to achieve the desired reaction outcome.
