Question

Write the correct formulas and balance the equation:

Gallium plus perchloric acid yields gallium perchlorate plus water plus dichlorine trioxide. ( the coefficient of water is 15 and the coefficient of dichlorine trioxide is 3).

Answer 1

Gallium = Ga(s)

Perchloric aci d= HClO4(aq)

Gallium perchlorate = Ga(ClO4)3

dichlorine trioxide = Cl2O3(aq)

water = H2O(l)

then

Ga(s) + HClO4(aq) =  Ga(ClO4)3 + H2O(l) + Cl2O3(aq)

balance ClO4

Ga(s) + 3HClO4(aq) =  Ga(ClO4)3 + H2O(l) + Cl2O3(aq)

use 15 factor help in water ; and 3 in Cl2O3

Ga(s) + 3HClO4(aq) =  Ga(ClO4)3 + 15H2O(l) + Cl2O3(aq)

balance H; then O, finally Cl

balance

8 Ga + 30 HClO4 = 8 Ga(ClO4)3 + 15H2O(l) + 3 Cl2O3
