Question

Please help ASAP! What would this coefficient be 2S02(g) + O2(g) --> ?S03(g)

Answer 1

The coefficient of SO3 is 2

Step-by-step explanation:

2SO2(g) + O2(g) —> ?SO3(g)

To know the coefficient of SO3 in the equation above, we must first balance the equation.

The equation can be balance as illustrated below:

2SO2(g) + O2(g) —> SO3(g)

There are 2 atoms of S on the left side and 1 atom on the right side. It can be balance by putting 2 in front of SO3 as shown below:

2SO2(g) + O2(g) —> 2SO3(g)

Now, we can see that the equation is balanced. Thus, the coefficient of SO3 is 2.
