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 : 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,

The balanced chemical reaction is,

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