The walls of your refrigerator must keep as much energy as possible from getting inside the refrigerator. The refrigerator will use a lot of this material, so the cost must be low. Which material would you use to make the refrigerator's inner walls?

I would use Aluminum because it helps keep things cool and cold, while in the freezer, I would the same thing.

hope this helps.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
