Balanced equation: 2 Al + 3 H 2 SO 4 = Al 2 (SO 4) 3 + 3 H 2 Reaction type: single replacement Sign in . When the following equation is balanced using the smallest possible integers, what is the coefficent of oxygen gas? Reaction stoichiometry could be computed for a balanced equation. Add a coefficient in front of Al on the reactant side. Here are some 2Al + 6H2O = 2Al(OH)3 + 3H2 (1) 2Al + 4H2O = 2AlO(OH) + 3H2 (2) 2Al + 3H2O = Al2O3 + 3H2 (3) C3H8O3 (g) + O2 (g) ? Now balance Al with 2, KOH with 2, 4 in front of H2SO4 because we have 4 SO4 on the right hand side. The equation is balanced.
