Answer:
The 3rd answer down.
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.
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
