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
Can someone please help

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction(unbalanced)

Zn+K₂CrO₄ ⇒ K + ZnCrO₄

Give coefficient

aZn+K₂CrO₄ ⇒ bK + cZnCrO₄

Zn, left=a, right=c⇒a=c

K, left=2, right=b⇒b=2

Cr, left=1, right=c⇒c=1⇒a=1

O,left=4,right=4c⇒4c=4⇒c=1

Reaction(balanced0

Zn+K₂CrO₄ ⇒ 2K + ZnCrO₄

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 Can someone please help
