Question

Which of the following coefficients balances the equation?

Coz(CrO4)3 + _BaCl2 → _CoCl2 + _BaCrO4

A) 1,2,2,2
B) 1,3,2,3
C) 1,3,1,3
D) 1,2,1,2

Answer 1

Option B) 1,3,2,3 correctly balances the equation, representing a chemical reaction that conserves the number of atoms of each element involved.

Step-by-step explanation:

The question is asking which set of coefficients correctly balances a chemical equation involving cobalt(III) chloride, barium chloride, cobalt(II) chloride, and barium chromate. After analyzing the stoichiometry of the given compounds, we find that Option B) 1,3,2,3 balances the equation Co2(CrO4)3 + 3BaCl2 → 2CoCl2 + 3BaCrO4.

Each chemical species has an equal number of atoms on both sides of the reaction, satisfying the Law of Conservation of Matter.
