Explanation:

1. For each of the following, convert the word equation into a formula equation, BUT do not balance!

a) Barium chlorate → Barium chloride + Oxygen

1. Chemical formulas

Barium chlorate:

It is a salt: an ionic compound.Barium has oxidation state +2Chlorate is the ion ClO₃⁻Swap the oxidation numbers to write the subscripts: 2 goes to ClO₃ and 1 goes to BaChemical formula Ba(ClO₃)₂It is solid: Ba(ClO₃)₂(s)

Barium chloride:

It is a salt: an ionic compountBarium has oxidation state +2Chlorine is in oxidation state -1Swap the numbers to write the subscripts: 2 goes to Cl and 1 goes to BaBaCl₂It is solid BaCl₂(s)

Oxygen:

It is a diatomic gas moleculeO₂(g)

2. Write the unbalanced molecular equation:

BaClO₃(s) → BaCl₂(s) + O₂(g)

b) Chlorine + Potassium nitride → Nitrogen + Potassium chloride

1. Chemical formulas

Chlorine:

It is a diatomic gas moleculeCl₂(g)

Potassum nitride

It is a saltPotassium has oxidation state +1Nitrogen is with oxidation state +3Swap the oxidation statesK₃NIt is solid: K₃N(s)

Nitrogen:

It is a diatomic gasN₂(g)

Potassium chloride

It is a salt (ionic compound)Potassium has oxidation state +1Chlorine is in oxidation state -1Swap the oxidation numbersKClIt is solid: KCl(s)

2. Write the unbalanced molecular equation

Cl₂(g) + K₃N(s) → N₂(g) + KCl(s)

c) Sodium nitride + Aluminum bromate → Aluminum nitride + Sodium bromate

1. Chemical formulas

Sodium nitride

It is a salt (ionic compound)Sodium has oxidation state +1Nitrogen is with oxidation state -3Swap the oxidation numbersNa₃NIt is in aqueous solutionNa₃N (aq)

Aluminum bromate

SaltAluminum has oxidation state +3Bromate is the ion BrO₃⁻Swap the oxidation statesAl(BrO₃)₃ (aq)

Aluminum nitride

Both Al and N have oxidation state 3, which simplyAlN(s). It is not soluble in water.

Sodium bromate

Na(BrO₃)₃ (aq)

2. Write the unbalanced molecular equation

Na₃N(aq) + Al(BrO₃)₃(aq) → AlN(s) + Na(BrO₃)₃(aq)This is a long answer with more than 5,000 charaters; thus, I have to add the rest of the explanations on a separate file.The attached file contains the complete answer.
