Question

Which of the following gives the balanced equation for this reaction?
K3PO4 + Ca(NO3)2 → Ca3(PO4)2 + KNO3
A) KPO4 + CaNO3 + KNO3
B) K3PO4 + Ca(NO3)2 → Ca3(PO4)2 + 3KNO3
C) 2K3PO4 + Ca(NO3)2 → Ca3(PO4)2 + 6KNO3
D) 2K3PO4 + 3Ca(NO3)2 → Ca3(PO4)2 + 6KNO3
E) K3PO4 + Ca(NO3)2 → Ca3(PO4)2 + KNO3

Answer 1

Answer : The correct option is, (D) $2K_3PO_4+3Ca(NO_3)_2\rightarrow Ca_3(PO_4)_2+6KNO_3$

Explanation :

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

The given unbalanced chemical reaction is,

$K_3PO_4+Ca(NO_3)_2\rightarrow Ca_3(PO_4)_2+KNO_3$

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of present on reactant side are not equal to the number of atoms of present on product side.

In order to balanced the chemical reaction, the coefficient 2 is put before the $K_3PO_4$, coefficient 3 is put before the $Ca(NO_3)_2$ and 6 is put before the $KNO_3$

Thus, the balanced chemical reaction will be,

$2K_3PO_4+3Ca(NO_3)_2\rightarrow Ca_3(PO_4)_2+6KNO_3$

Hence, the correct option is, (D)

Answer 2

The balanced equation from the reaction is 2K3PO4 + 3Ca(NO3)2 → Ca3(PO4)2 + 6KNO3

What is Balanced chemical equation?

A balanced chemical equation refer to equation when the number of the atoms involved in the reaction in the reactants side is equal to the number of atoms in the products side.

Both atoms on the two side are equal.

Therefore, The balanced equation from the reaction is 2K3PO4 + 3Ca(NO3)2 → Ca3(PO4)2 + 6KNO3 because the number of atom on the reactants side is equal to the number of atom on the product side.
