The volume of the reactants is greater than the volume of the products.

The total energy of the reactants is equal to the total energy of the products.

Answer:

D) The temperature of the reactants is greater than the temperature of the products.

Explanation:

All the answers:

1. A) The reactants are unlit charcoal, and the products are charcoal that has already burned and released its energy

2. C) sugar + oxygen → carbon dioxide + water + energy

3. D)  iron + oxygen → rusted iron + energy

4. A) an endothermic reaction, because ice absorbs heat to become liquid water

5. D) The temperature of the reactants is greater than the temperature of the products.

We can argue that a reaction is endothermic when the temperature of the reactants is greater than the temperature of the products.

What is an endothermic reaction?

An endothermic reaction is a chemical reaction accompanied by the absorption of heat.

Comparing the reactants and the products of a chemical reaction, which observation can best be used to argue that the reaction is endothermic?

  • The volume of the reactants is greater than the volume of the products. False. There is no relation between the volume and the endothermicity.
  • The total energy of the reactants is equal to the total energy of the products. False. If the total energy is equal, there is no heat (energy) absorption.
  • There are fewer chemical bonds in the reactants than there are chemical bonds in the products. False. We must consider not only the number of bonds, but also their energies, to establish if a reaction is endothermic.
  • The temperature of the reactants is greater than the temperature of the products. True. If the reaction is endothermic and absorbs heat from the surroundings, the temperature of the reactants will be greater than the temperature of the products.

We can argue that a reaction is endothermic when the temperature of the reactants is greater than the temperature of the products.
