Zinc methoxide and acetic acid react together to form methanol and zinc acetate

The sodium methoxide reacts with the water to produce sodium hydroxide an methanol.

No. Magnesium methoxide will react with water to form a gel. The gel is actually a cross-linked Magnesium hydroxide structure in methanol. Magnesium methoxide is typically sold/stored in dry methanol to protect the chemical as it is incredibly hygroscopic.

The methoxide ion would steal a hydrogen ion from water, forming sodium hydroxide and methanol.
