Why does the glass of water weigh less after the pill has dissolved? Why does the glass of water weigh less after the pill has dissolved? Nitrogen dioxide gas will be generated and released as the anti-acid pill dissolves.

Assume that the potential energy of the products in a chemical reaction is 60 kilojoules. this reaction would be exothermic if the potential energy of the reactants were

According to the collision theory, when can a chemical reaction occur? When enough activation energy is added to correct the orientation of the particle collisions When reactants collide with enough energy to intersect their valence shells and form

Why is ice less dense than water? A. When water freezes, it forms a crystal structure with less volume than liquid water. B. Ice crystallizes with an open structure, and the gaps that form between the water molecules in ice increase its volume. C.
