With that information you can sketch the energy of the reaction as it progresses.

You can find the sketch in the pdf file attached.

You will see that the reactants start at a certaing energy level, that level increases in 75 kJ/mol, which is the activation energy.

The intermediate products are 75kJ/mol above the energy level of the reactants.

Given that the reaction is exhotermic. The reaction will release a net heat and the products will be at a lower energy level than the reactants, which is shown by the fact that the products are placed below the level of the reactants.

Answer:

D. 4Al + 3O2 → 2Al2O3

Explanation:

Chemical reactions involves the chemical combination of two or more substances called REACTANTS to yield other substances called PRODUCTS. However, in accordance with the LAW OF CONSERVATION OF MASS, the amount of reactants must be equal to that of the products.

To accomplish this, the reaction must be BALANCED. A balanced equation is an equation in which the number of atoms of each element in the reactant side equals the number of atoms in the product side. In this reaction involving Aluminum and Oxygen to give Aluminum oxide as follows:

Al + 02 → Al2O3

A coefficient is used to balance the number of atoms on both sides of the equation as follows:

4Al + 3O2 → 2Al2O3
