Question

Answer ASAP please ! When sodium (Na) and chlorine (Cl) are combined, a small amount of table salt is formed and a bright yellow light and a lot of heat are given off. Does it take more energy to break the bonds of the reactants, or is more energy released when forming the bonds of the products? How do you know?

a. More energy is released when forming the bonds of the products because a lot of heat is given off, which indicates energy was released.
More energy is released when forming the bonds of the products because a lot of heat is given off, which indicates energy was released.

b. It takes more energy to break the bonds of the reactants because yellow light is given off, which indicates energy was absorbed in the beginning.

Answer 1

More energy is released when forming the bonds of the products because a lot of heat is given off, which indicates energy was released.

Step-by-step explanation:

The heat energy is a better indicator of how much energy is used and where.
