Balancing practice
_P4O10 + _H2O → _H3PO4
P4O10 + 6H2O → 4H3PO4
Identify the type of chemical reaction and balance the following equation:
_Pb(OH)2 + _HCl → _H2O + _PbCl2
Neutralization
Pb(OH)2 + 2HCl → 2H2O + PbCl2
Identify the type of chemical reaction and balance the following equation:
_C3H8 + _O2 → _CO2 + _H2O
Combustion reaction
C3H8 + 5O2 → 3CO2 + 4H2O
_AlBr3 + _K2SO4 → _KBr + _Al2(SO4)3
2AlBr3 + 3K2SO4 → 6KBr + Al2(SO4)3
