Question

Magnesium phosphate reacts with sulfuric acid to form magnesium sulfate and phosphoric acid. what is the coefficient for sulfuric acid when the equation is balanced using the lowest, whole-numbered coefficients?

Answer 1

Magnesium phosphate react with sulfuric acid to form magnesium sulfate and phosphoric acid
word equation
magnesium phosphate +sulfuric acid --->magnesium sulfate +phosphoric acid

balanced chemical equation
Mg(PO4)2 +3H2SO4 --->3Mg(S04) +2H3PO4
1 mole of Mg(po4)2 react with 3 moles of H2SO4 to from #moles of Mg(so4) and 2 moles of H3PO4

Answer 2

Answer : The coefficient of sulfuric acid is, 3 and the balanced chemical reaction will be,

`Mg_3(PO_4)_2+3H_2SO_4\rightarrow 3MgSO_4+2H_3PO_4`

Explanation :

Balanced chemical equation : It is defined as the number of atoms of individual elements present on reactant side always be equal to the product side.

The balanced chemical reaction will be,

`Mg_3(PO_4)_2+3H_2SO_4\rightarrow 3MgSO_4+2H_3PO_4`

By the stoichiometry we can say that, 1 mole of magnesium phosphate react with 3 moles of sulfuric acid to give 3 moles of magnesium sulfate and 2 moles of phosphoric acid.

The coefficient of magnesium phosphate = 1

The coefficient of sulfuric acid = 3

The coefficient of magnesium sulfate = 3

The coefficient of phosphoric acid = 2
