Answer :
1) Balance the chemical equation
[tex]Ca(OH)_2+HNO_3\rightarrow H_2O+Ca(NO_3)_2[/tex]List the elements (or polyatomic ions) in the reactants
Ca: 1
OH: 2
H: 1
NO3: 1
List the elements (or polyatomic ions) in the products
Ca: 1
NO3: 2
H: 2
O: 1
Calcium is already balanced.
Balance nitrogen
[tex]Ca(OH)_2+2HNO_3\rightarrow H_2O+Ca(NO_3)_2[/tex]Reactants:
Ca: 1
OH: 2
H: 2
NO3: 2
Products:
Ca: 1
NO3: 2
H: 2
O: 1
Balance hydrogen
[tex]Ca(OH)_2+2HNO_3\rightarrow2H_2O+Ca(NO_3)_2[/tex]Reactants:
Ca: 1
O: 8
H: 4
N: 2
Products:
Ca: 1
O: 8
H: 4
N: 2
