Question

Select the correct sequence of coefficients for the following reaction:

V + O2 -> 12O5

A. 1, 2, 12.
B. 1, 12, 5.
C. 2, 1, 12.
D. 2, 12, 1.

Answer 1

The correct coefficients for the reaction V + O2 -> V2O5 are 4, 5, and 2, respectively, to maintain the balance of atoms and molar amounts on both sides of the equation.

Step-by-step explanation:

The correct sequence of coefficients for the given reaction V + O2 -> V2O5 is not listed among the options provided. Each chemical equation must be balanced in terms of atoms and molar amounts of each element on both sides. In this case, the correct coefficients that balance the equation are 4 V + 5 O2 -> 2 V2O5. These coefficients give us a balanced equation with 8 atoms of V and 10 atoms of O on both sides. The correct sequence of coefficients for the given reaction is D. 2, 12, 1. The balanced equation for the reaction is:

2V + 12O2 -> 12VO5

In this balanced equation, there are 2 moles of V, 12 moles of O2, and 12 moles of VO5.
