Chemistry Exam 3

Balance the following rxn: Al (s) + H2SO4 (aq) → Al2(SO4)3 (aq) + H2 (g)

2Al(s) + 3H2SO4(aq) = Al2(SO4)3(aq) + 3H2(g)

Balance the following rxn: C5H12 (l) + O2 (g) → CO2 (g) + H2O(g)

C5H12(l) + 8O2(g) = 5CO2(g) + 6H2O(g)

Balance the following rxn: C5H8 (l) + O2 (g) → CO2 (g) + H2O (g)

C5H8(l) + 7O2(g) = 5CO2(g) + 4H2O(g)

Balance the following rxn: K2SO4 (aq) + Ca(NO3)2 (aq) → CaSO4 (s) + KNO3 (aq)

K2SO4(aq) + Ca(NO3)2(aq) = CaSO4(s) + 2KNO3(aq)

Balance the following rxn: N2H4 (g) + H2O2 (g) → N2 (g) + H2O(g)

N2H4(g) + 2H2O2(g) = N2(g) + 4H2O(g)
