Question

6) When gasoline burns, it reacts with oxygen in the air and forms hot gases consisting of carbon dioxide and water vapor. How does the potential energy of the gasoline and oxygen compare with the potential energy of the carbon dioxide and water vapor? Explain by selecting all true statements.a) The potential energy of the products is lower than the potential energy of the reactants.b) Heat is absorbed by the system.c) The potential energy of the products is higher than the potential energy of the reactants.d) Heat is released by the system.

Answer 1

According to the given information we can conclude that the potential energy of the products is lower that the potential energy of the reactants and therefore, heat is released by the system.

It means that the correct answers are a and d.
