1. define chemical reaction, reactant, product ,conservation of mass, isotopes ,
isobars​

Answer 1

A chemical reaction is any mixture of substances that generates new substances as a product

A reactant is the substance that is used in a chemical reaction to get the product

A product is the substance generated in a chemical reaction

Conservation of mass is a law in chemistry which the mass of reactants and mass of products must always be the same

Isotopes are atoms of the same elements (same amount of protons) but different masses

Isobars are atoms of different elements (varying amounts of protons) but the same mass
