- (B) The balanced reaction equation for the combustion of butane is
2C 4 H 10 (g) + 13O 2 (g) → 8CO 2 (g) + 10H 2 O(g)Use dimensional analysis:(Please note: you will not have a calculator when you solve problems
like this while taking the test. By using mental math, you should be able
to evaluate the first part of the problem as 0.500 moles of butane. Since
8 is 4 times 2, the next factor shows that you need to multiply 0.500 by
4 to get the final answer, 2.00 moles CO 2 .)
