(A) Why do we balance a chemical equation? Name and state the law that suggests the balancing of a chemical equation? Balance the following chemical equation :
Zn + H3PO4 → Zn3(PO4)2 + H2
Solution
(A)
The number of atoms of each element remains same before and after a chemical reaction / to satisfy the law of conservation of mass.
Law of conservation of mass.
Mass can neither be created nor destroyed in a chemical reaction.
3Zn + 2H3PO4 → Zn3(PO4)2 + 3H2
