Question

Example of reactants
Please help!

Answer 1

reactants are those substances which react together to form product, for example hydrogen and oxygen reacts to form water molecules, therefore here reactants are hydrogen and oxygen

Answer 2

H2 (hydrogen gas) and O2 (oxygen gas) are reactants in the reaction that forms liquid water: 2 H2(g) + O2(g) → 2 H2O(l). Notice mass is conserved in this equation.
