What are the products in this chemical reaction?

A. [tex]3CO_2 + 4H_2O + \text{energy}[/tex]
B. [tex]4H_2O + 5O_2[/tex]
C. [tex]C_3H_8 + 5O_2[/tex]
D. [tex]C_3H_3 + 3CO_2 + \text{energy}[/tex]



Answer :

To determine the correct products of the chemical reaction given by the equation [tex]\( C_3 H_8 + 5 O_2 \rightarrow 3 CO_2 + 4 H_2O + \)[/tex] energy, we need to analyze the equation step by step.

### Step-by-Step Solution:

1. Examine the given chemical reaction:
[tex]\[ C_3 H_8 + 5 O_2 \rightarrow 3 CO_2 + 4 H_2O + \text{energy} \][/tex]

2. Identify the reactants:
- The substances on the left side of the arrow are the reactants.
- In this case, the reactants are [tex]\( C_3 H_8 \)[/tex] (propane) and [tex]\( 5 O_2 \)[/tex] (oxygen).

3. Identify the products:
- The substances on the right side of the arrow are the products.
- Here, the products are [tex]\( 3 CO_2 \)[/tex] (carbon dioxide), [tex]\( 4 H_2O \)[/tex] (water), and energy.

4. Match the products to the given choices:
A. [tex]\( 3 CO_2 + 4 H_2O + \)[/tex] energy
B. [tex]\( 4 H_2O + 5 O_2 \)[/tex]
C. [tex]\( C_3 H_8 + 5 O_2 \)[/tex]
D. [tex]\( C_3 H_3 + 3 CO_2 + \)[/tex] energy

5. Compare each option:
- Option A: [tex]\( 3 CO_2 + 4 H_2O + \)[/tex] energy matches the products found on the right side of the original equation.
- Option B: [tex]\( 4 H_2O + 5 O_2 \)[/tex] are not the correct products since they include oxygen as a reactant.
- Option C: [tex]\( C_3 H_8 + 5 O_2 \)[/tex] are the reactants, not the products.
- Option D: [tex]\( C_3 H_3 + 3 CO_2 + \)[/tex] energy is incorrect since [tex]\( C_3 H_3 \)[/tex] is not present in the products.

6. Conclusion:
The correct products of the chemical reaction [tex]\( C_3 H_8 + 5 O_2 \rightarrow 3 CO_2 + 4 H_2O + \)[/tex] energy are found in Option A.

So, the answer to the question "What are the products in this chemical reaction?" is:

A. [tex]\( 3 CO_2 + 4 H_2O + \)[/tex] energy
