Question

Explain the term reactant and product giving examples.

Answer 1

Substances which react chemically in a reaction to give new substances are called reactants.The new substances formed are called the products.The products do not retain the properties of the reactants as they have lost the m during the chemical reaction.
Eg.When two hydrogen atoms react with two chlorine atoms(reactants),they give a completely new compound (product), hydrochloric acid(two molecules).
h2+cl2>2hcl
When two sodium atoms react with two chlorine atoms(reactants),they give a completely new compound (product),sodium chloride (two atoms).
2na+cl2>2nacl

Answer 2

Which undergoes reaction is called reactant...And which results at the end of reaction is called product...for eg:c+o2______co2,here c and o are reactants,where as co2 is product
