Given the potential energy diagram representing a reaction below, which numbered interval represents the heat of reaction?

The potential energy diagram has been representing the heat of reaction at interval 2.

The heat of reaction has been defined as the difference in the heat of product and reactant. The potential energy has been the stored energy of the compounds.

In the given potential energy curve, the heat of reaction has been found to be the increase in potential energy. There has been an increment in the energy at interval 2.

Thus, the potential energy diagram has been representing the heat of reaction at interval 2.

2

Explanation:

Heat of reaction is usually the difference of heat of products and heat of reactions. The difference here is represented by the letter 2.

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
