Question

What type of reaction is depicted by this equation? 2C4H10(g) + 13O2(g) d 8CO2(g) + 10H2O(g)

A)combustion
B)single-replacements
C)combination
D)decomposition

Answer 1

Answer: A)combustion

Explanation: I took the test and this was the correct answer.

Also, it can’t be B because it might look like the oxygen is replacing the hydrogen, but it’s not because it gains oxygen.

It can’t be C because it doesn’t yield one product. You can tell by the plus sign that there are two sections of the product.

Lastly it can’t be a decomposition because it doesn’t start off with one single product initially.

Answer 2

This is a combination reaction, where a hydrocarbon reacts in the presence of oxygen to produce carbon dioxide and water.
