For each molecule of [tex]\( C_4H_8 \)[/tex] that reacts, how many molecules of carbon dioxide and water are produced?

A. Two carbon dioxide molecules and two water molecules
B. Four carbon dioxide molecules and four water molecules
C. Two carbon dioxide molecules and four water molecules
D. Four carbon dioxide molecules and two water molecules



Answer :

To determine the products formed during the combustion of one molecule of [tex]\( C_4H_8 \)[/tex], we first need to refer to the balanced chemical equation for its combustion. The balanced equation for the combustion of butene ([tex]\( C_4H_8 \)[/tex]) is:

[tex]\[ C_4H_8 + 6O_2 \rightarrow 4CO_2 + 4H_2O \][/tex]

Let's break down what this equation tells us:

1. One molecule of [tex]\( C_4H_8 \)[/tex] reacts with six molecules of [tex]\( O_2 \)[/tex] (oxygen).
2. This reaction produces four molecules of [tex]\( CO_2 \)[/tex] (carbon dioxide).
3. Additionally, the reaction produces four molecules of [tex]\( H_2O \)[/tex] (water).

Therefore, for each molecule of [tex]\( C_4H_8 \)[/tex] that reacts:

- Number of carbon dioxide ([tex]\( CO_2 \)[/tex]) molecules produced: 4
- Number of water ([tex]\( H_2O \)[/tex]) molecules produced: 4

Thus, the correct response to the question is:

#### For each molecule of [tex]\( C_4H_8 \)[/tex] that reacts:
- Four molecules of carbon dioxide are produced.
- Four molecules of water are produced.

So, the correct choice is:

Four carbon dioxide molecules and four water molecules.
