Answer: Compound . Chemical reactions can divide elements into simpler substances, but they cannot separate elements into simpler substances. Physical or chemical characteristics of substances can be categorised.
Compounds and elements can be created from pure substances. A chemical reaction is required to break down pure substances (elements and compounds) into their component atoms or elements. This is known as the chemical separation process. Physical separation of pure substances is impossible.
Explanation:
What makes something pure substance?
One element or a small number of related compounds make up pure substances. Mixtures are assemblages of many components. Mixtures of two or more substances (or elements) that cannot be visually distinguished from one another are referred to as homogeneous mixtures.
What sort of compound would that be?
A substance made up of two or more components is called a compound. Table salt, water, and carbon dioxide are a few examples of compounds

You cannot find it if you do not know the information. Was there a molar mass given or do you know if it is asking for the molar mass?
Answer:
3.88%
Explanation:
Given parameters:
Grams of solute = 3.55g of NaCl
Grams of solution = 91.55g of solution
Mass percentage
of NaCl(%) = grams of solute/grams of solution x 100
Mass percent = 3.55/91.55 x 100
Mass percent = 3.88%
What happens to a reactant molecules when forming product molecules is that they form different properties.
