Enter the balanced molecular equation: hc2h302(aq) +mg(oh) 2(s) and enter the balanced ionic equation hc2h302(aq)+mg(oh)2(s)

2HC₂H₃O₂(aq) + Mg(OH)₂(s)⟶ Mg²⁺(aq) + 2C₂H₃O₂⁻(aq) + 2H₂O(ℓ)  

Explanation:

An ionic equation uses the symbols (aq) [aqueous] to indicate molecules and ions that are soluble in water, (s) [solid] to indicate insoluble solids, and (ℓ) to indicate substances (usually water) in the liquid state.

This reaction is an acid-base neutralization, in which a weak acid reacts with an insoluble base to form water and a soluble salt.

1. Molecular equation

2HC₂H₃O₂(aq) + Mg(OH)₂(s) ⟶ Mg(C₂H₃O₂)₂(aq) + 2H₂O(ℓ)

2. Ionic equation

Magnesium acetate is a soluble ionic compound, so we write it as hydrated ions.

2HC₂H₃O₂(aq) + Mg(OH)₂(s)⟶ Mg²⁺(aq) + 2C₂H₃O₂⁻(aq) + 2H₂O(ℓ)

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
