Answer from: mbarron279542

(i) Formula = Fe₂(SO₄)₃

Name = Iron (III) Sulfate or ferric sulfate

(ii) Formula (NH₄)₂CO₃

Name = Ammonium Carbonate

Explanation:

Data given:

(i) Fe³⁺ and SO₄²⁻

ii) NH₄⁺ and CO₃²⁻

Formula and named of the compound =?

Solution:

(i) compound from Fe³⁺ and SO₄²⁻ and its name

writing a formula in combined form

The symbols of two ions written together that is FeSO₄The charges shown on each atom is its valency and it show its combining tendency so iron will combine with 3 sulfate ions and sulfate ion will combine with 2 iron ionsWhen two ions combine their valencies should be write on the base of the alternate ions. that is 2 will be at the base of Fe and 3 will be at the base of SO₄ without chargesSo the combined formula and name will be

compound formula form from Fe³⁺ and SO₄²⁻ = Fe₂(SO₄)₃

Name of the compound = Iron (III) Sulfate or ferric sulfate

(ii) compound from NH₄⁺ and CO₃²⁻ and its name

writing a formula in combined form

The symbols of two ions written together that is NH₄CO₃The charges shown on each atom is its valency and it show its combining tendency so NH₄⁺ will combine with 1 carbonate ion and carbonate ion will combine with two NH₄⁺ ionsWhen two ions combine their valencies should be write on the base of the alternate ions 1 should not be written. 2 will be at the base of NH₄⁺ without chargeSo the combined formula and name will be

compound formula form from NH₄⁺ and CO₃²⁻ = (NH₄)₂CO₃

Name of the compound = Ammonium Carbonate

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
