Calcium Carbonate + HNO3
by Betty Dejene
Types of Reaction
Calcium Carbonate and Hydrogen Nitrate is aqueous. Calcium Nitrate and Hydrogen Carbonate is aqueous too.
Ca(CO3) + 2 HNO3 Ca(NO3)2 + H2 CO3
Type of reaction that occurs when the cations and anions switch between two reactants to form new products.
Molar mass of each reactant and products.
HNO3 H= 1.008+ + N=14.007+ O=15.999(3)= 47.997g/mole
Ca(NO3)2 Ca=40.078+ N=14.007(2) + O=15.999(6) = 164.086g/mole
H2CO3 H=1.008(2)++ C=12.011+O=15.999(3) =47.997g/mole
Mole to Mole conversions
3.21 mole Ca(CO3) times 1 mole H2CO3 divided by
_ 1mole Ca(CO3) 1 Mole Ca(CO3) = 3.21 mole H2CO3
Mass to Mass conversion

Limiting and excess reactants
12.3g Ca(CO3) times 1 mole Ca(NO3)2 times 1 mole H2CO3 times 62.012 mole HNO3 divided by
_ times 100.086 g Ca(CO3) times 1 mole Ca(CO3)2 times 1 mole HNO3
12.3 g HNO3 times 1 mole HNO3 times 1 mole H2CO3 times 62.024 g H2CO3 divided by
_ 63.012 HNO3 times 2 mole HNO3 times 1 mole H2CO3
12.3g Ca(CO3) is excess. 12.3 g HNO3 is limited because 6.05 is less then 7.62
The theoretical yield is the amount predicted by a stoichiometric calculation based on the number of moles of all reactants present. This calculation assumes that only one reaction occurs and that the limiting reactant reacts completely.
defined as the actual yield/theoretical yield x 100
4.87 divided by 6.05 = .804 times 100 = 80.49%
