Given the hypothetical elements above, solve the following problem:

In the unbalanced equation, AB + C2 → AC3 + B2, what is the mole ratio between C2 and B2?

A. 2:2
B. 3:1
C. 1:3

1 answer

To determine the mole ratio between C2 and B2, we first need to balance the equation:

2AB + 3C2 → 2AC3 + B2

Now that the equation is balanced, we can see that for every 3 moles of C2, there are 1 mole of B2.

Therefore, the mole ratio between C2 and B2 is:

B. 3:1
