Question

For the reaction shown below, which statement is correct? CH₄+2O₂→CO₂+2H₂O+heat

A. The products contain more energy.
B. The reactants contain more energy.
C. The reactants and products must contain the same amount of energy.
D. It is not possible to tell whether the reactants or products contain more energy.

Answer 1

In the given reaction CH₄+2O₂→CO₂+2H₂O+heat, the correct statement is that the products contain more energy.

Step-by-step explanation:

The given reaction is:

CH4+2O₂→CO₂+2H₂O+heat

To determine which statement is correct, we need to understand the concept of energy in chemical reactions. In an exothermic reaction, the products contain less energy than the reactants, while in an endothermic reaction, the products contain more energy than the reactants.

In this reaction, heat is a product, which means that energy is released into the surroundings. Therefore, the correct statement is B. The products contain more energy.
