balance the equation pls

Answer 1

For 1: The balanced chemical equation is $2Fe(OH)_3+3H_2SO_4\rightarrow Fe_2(SO_4)_3+6H_2O$

For 2: The balanced chemical equation is $Al_2(CO_3)_2+4HNO_3\rightarrow 2Al(NO_3)_2+2CO_2+2H_2O$

For 3: The balanced chemical equation is $3K_2CO_3+2H_3PO_4\rightarrow 2K_3PO_4+3CO_2+3H_2O$

For 4: The balanced chemical equation is $3CaCO_3+2H_3PO_4\rightarrow Ca_3(PO_4)_2+3CO_2+3H_2O$

Explanation:

Every balanced chemical equation follows law of conservation of mass.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

For the given options:

• For 1: Iron (III) hydroxide + sulfuric acid = Iron (III) sulfate + water

The balanced chemical equation follows:

$2Fe(OH)_3+3H_2SO_4\rightarrow Fe_2(SO_4)_3+6H_2O$

By Stoichiometry of the reaction:

2 moles of iron (III) hydroxide reacts with 3 moles of sulfuric acid to produce 1 mole of iron (III) sulfate and 6 moles of water

• For 2: Aluminium carbonate + nitric acid = Aluminium nitrate + carbon dioxide + water

The balanced chemical equation follows:

$Al_2(CO_3)_2+4HNO_3\rightarrow 2Al(NO_3)_2+2CO_2+2H_2O$

By Stoichiometry of the reaction:

1 mole of aluminium carbonate reacts with 4 moles of nitric acid to produce 2 moles of aluminium nitrate, 2 moles of carbon dioxide and 2 moles of water

• For 3: Potassium carbonate + phosphoric acid = Potassium phosphate + carbon dioxide + water

The balanced chemical equation follows:

$3K_2CO_3+2H_3PO_4\rightarrow 2K_3PO_4+3CO_2+3H_2O$

By Stoichiometry of the reaction:

3 moles of potassium carbonate reacts with 2 moles of phosphoric acid to produce 2 moles of potassium phosphate, 3 moles of carbon dioxide and 3 moles of water

• For 4: Calcium carbonate + phosphoric acid = Calcium phosphate + carbon dioxide + water

The balanced chemical equation follows:

$3CaCO_3+2H_3PO_4\rightarrow Ca_3(PO_4)_2+3CO_2+3H_2O$

By Stoichiometry of the reaction:

3 moles of calcium carbonate reacts with 2 moles of phosphoric acid to produce 1 mole of calcium phosphate, 3 moles of carbon dioxide and 3 moles of water
