Answer:
D.
Explanation:
chemical erosion is where the composition of a rock changes.
Based on the data provided, the total energy of the reaction is 1066 kJ and the reaction is endothermic
<h3>What is the total energy of a reaction?</h3>
The total energy change of a reaction is the difference between the total bond energy of the reactants and the total bond energy of the products.
- If the total change in bond energy is positive, the reaction is endothermic.
- If the total change in bond energy is negative, the reaction is exothermic.
- The total energy change of a reaction = bond energy of reactants - bond energy of products
Bond energy of reactants = 2000 kJ
Bond energy products = 934 kJ
Total energy of reaction = (2000 - 934) kJ = 1066 kJ
The total energy of the reaction is 1066 kJ and the reaction is endothermic.
