2HNO3 + CaCO3 ==> CO2 + H2O + Ca(NO3)2
H2SO4 + CaCO3 ==> CO2 + H2O + CaSO4
You can turn them into ionic and net ionic equations.
Lakes that have been acidified by acid rain (HNO3 and H2SO4) can be neutralized by a process called liming, in which limestone (CaCO3) is added to the acidified water.
What mass of limestone (in kg) would be required to completely neutralize a 15.3 billion-liter lake that is 1.7×10^−5M in H2SO4 and 8.8×10−6M in HNO3?
