Identify the base in this acid-base reaction:
o
2HC2H3O2 + Mg(OH)2 + Mg(C2H2O2)2 + 2H2O
O HC2H302
O Mg(OH)2
O Mg(C2H302)2
o H₂O
DONE

Magnesium hydroxide, Mg(OH)2

Explanation:

2HC2H3O2(aq) + Mg(OH)2(aq) → Mg(C2H2O2)2(aq) + 2H2O(l)

Acid + base → Salt + Water.

The equation above is an example of an acid-base reaction where the acid, aqeous 2HC2H3O2 reacts completely with an appropriate amount of the base, aqueous Mg(OH)2 to produce salt, aqueous Mg(C2H2O2)2 and water, liquid H2O only.

This acid-base reaction is also known as neutralization reaction.

well in order to answer this question you have to provide more information < 3

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
