Na²O (sodium oxide) will be a base when exposed to water H²O

Explanation:

Sodium Oxide Na²O, will become Sodium Hydroxide after being exposed to water (at 80% I believe).

The oxygen ion in Na²O has 2 extra electrons which makes it highly charged and very attractive to hydrogen ions. The attraction is so strong that when Na²O comes in contact with H²O, the O(-2) strips off a hydrogen from water, forming 2 x OH ions which of course are still strongly basic.

When aluminum, Al, metal is dipped in an aqueous solution of hydrochloric acid, HCl, hydrogen gas, H2, is produced with the form
Alex17521 [72]

Answer:

2Al (s) +  6HCl (aq) → 2 AlCl3 (aq)  +  3H2 (g)↑  

Explanation:

- We can put an up arrow to H2 cause as it is a gas, it can be released to the atmosphere.

- Aluminum as metal must be solid.

- As we have two solutions, both are aqueous phase.

- The stoichiometry must match on both sides of the reaction to have the same amount of elements of each compound.}

Reactants : 2 Aluminun

6 Hydrogen

6 Chloride

Products:

2 Aluminun

2.3 = 6 Chloride

3.2 = 6 Hydrogen
