Balancing the following equations:
(a)ag + h2s + o2 = ag2s + h2o4
(b)p4 + o2 = p4o10
(c)pb + h2o + o2 = pb(oh)2
(d)fe + h2o -> fe3o4 + h2
(e)sc2o3 + so3 = sc2(so4)3
(f)ca3(po4)2 + h3po4 = ca(h2po4)2
(g)al + h2so4 = al2(so4)3 + h2
(h)ticl4 + h2o = hcl + tio2

Explanation:

Law of Conservation of mass is defined as mass cannot be created nor be destroyed.In a balanced chemical equation total mass of reactant are equal to the total mass of the products.

In a balanced chemical equation total number of an individual atoms on both sides are same.
