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.

Which laws can be combined to form the ideal gas law?
Degger [83]
Answer: Charles's law, Avogadro's law and Boyle's law.

Explanation:

Boyle's law is: at constant temperature  PV = constant

Charles law is: at constant pressure V/T = constant

Avogadro's law is: at constant pressure ant temperature, equal volume of gases contain equal number of moles: V/n = constant

Ideal gas law: PV/nT = constant => PV = nT*constant = PV = nTR
