Comparing the reactants and the products of a chemical reaction, which observation can best be used to argue that the reaction is endothermic?(1 point) 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.

There are fewer chemical bonds in the reactants than there are chemical bonds in the products.

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

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.
