Question

What are the coefficients that would correctly balance this equation? __Zn+__K2CrO4 > __K + __ZnCrO4
A. 2,1,2,1
B. 1,2,3,1
C. 1,2,1,2
D. 1,1,2,1

Answer 1

Answer : The correct option is, (D)

Explanation :

Balanced reaction : Balanced reactions are those reactions when the number of different atoms of the element present in the reactant sides is equal to the product sides.

The given unbalanced reaction is,

$Zn+K_2CrO_4\rightarrow K+ZnCrO_4$

The balanced chemical reaction is,

$Zn+K_2CrO_4\rightarrow 2K+ZnCrO_4$

Therefore, 1, 1, 2, 1 are the coefficients that would correctly balance this equation.

Answer 2

The coefficient of the balanced equation for $\rm Zn^+$is 1, $\rm K_2CrO_4$ is 1, $\rm K^+$ is 2, and $\rm ZnCrO_4$ is 1.

The chemical reactions are the ones in which the formation of the products has been taken place by the combination or the dissociation of the reactants.

The chemical reaction can be termed as the balanced chemical reaction when the elements on both the side of the reactant and the product have been equal.

In the given chemical reaction, $\rm Zn^+\;+\;K_2CrO_4\;\rightarrow\;K^+\;+\;ZnCrO_4$

• The atoms of Zn have been equal on both the product and reactant side to be 1.

• The atoms of $\rm CrO_4$ on both the product and the reactant side have been equal.

• The atoms of K on the product side have been 2, while on the reactant side has been 1. Thus the coefficient has been added to the K on the product side.

The balanced reaction will be: $\rm Zn^+\;K_2CrO_4\;\rightarrow\;2\;K^+\;ZnCrO_4$.

The coefficient of the balanced equation for $\rm Zn^+$is 1, $\rm K_2CrO_4$ is 1, $\rm K^+$ is 2, and $\rm ZnCrO_4$ is 1.
