Complete and balance the following equations according to acid and base behavior in water. phases are optional. hf h20

Acids and bases dissociate in water into their original positive and negative ions. A strong acid/base would completely dissociate while a weak acid/base would partially dissociate.
Note: s stands for solid, l stands for liquid and g stands for gas.

(1) HF:
HF is an acid that dissociates in water as follows:
HF (g) > H+ + F-

(2) Ba(OH)2:
Ba(OH)2 is a base that dissociates in water as follows:
Ba(OH)2 (s) > Ba2+ + 2OH-

(3) HNO3:
HNO3 is an acid that dissociates in water as follows:
HNO3 (l) > H+ + (NO3)-

The answer to that would be magnesium
