Question

6. Write the correct formulas and balance the equations: A. Gallium plus perchloric acid yields gallium perchlorate plus water plus chlorine. (Note: the coefficient of the water is 24 and the coefficient of chlorine is 3.)

Answer 1

- For chemical Reaction Gallium + perchloric aod - Galliumpeschicross + bater + chlonne + Cl2 & Gacclou) + H₂O We & Helou Go and coefficient cly has a - Given H₂O has au 3 Galceou), +94 +₂0 + 302 . Ga + Halou 3 ie we have 24x2= 48 H atom. - To balance 46 H atoms multiply treou by 42 = Ga + 48HClOy - Ga (clow, +244₂0 + 302 Sina chlorine is 48 on reactant side and 9 (3+342) . on product side. . To balance ce atorms, multiply - Ga (cloy) by ons 14 s [lux 3 + 6 = 48) 12

Go + 48Hclou 14 Ga Chooy) +24 H₂O +342 Now, to balance Ga atoms, multiply 19 +4 +3012 14 Ga + 48Hcloy - 14 Galceau), +24H₂O Check oxygen on both the sides React ant side = 48x4 = 192 o atoms Product side = 14x3x4 + 24 = 168 +2u = 192 o-atom a As all elements are balanced on both sides - reaction is balanced 14 Ga + 48 #clou 14 Gaccea +24 H₂O +3023
