Why do magnesium and oxygen need to be heated for a reaction to occur?​

Chemistry
1 answer:
Alexxandr [17]3 years ago
7 0

Because flame provides a source of heat so that the magnesium metal atoms can overcome their activation energy. Activation energy is the minimum energy required in order for a chemical reaction to proceed. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide.

What happens when sodium and cholorine are mixed
tigry1 [53]

Answer:

The short of it is you would create salt.

Explanation:

If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.
