Question

calculate the ratio of the masses of the reactants and products in the following reactions:
1.Zn H2SO4=ZnSO4+H2
2.2H2+O2=2H2O
3.NaOH+HCl=NaCl+H2O
4.2KClO3=2KCl+3O2
5.2KNO3=2KNO2+O2​

Answer 1

Answer:

All parts 1:1

Explanation:

All chemical reactions follow Law of Conservation of mass which states that mass can neither be created nor be destroyed.

that means you can calculate mass of reactant and products but their total mass will remain same ie ratio=1:1.
