No it depends on the molecules strength
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.
The answer is B. bases measure below seven
think of it like this 7 is neutral going down from seven it rises in acidity and going up from seven increases in alkalinity
objects in motion tend to stay in motion unless acted upon by an outside force.
