Answer 1

1)Calculate the molarity of each of the following solutions.

0.30 mol of LiNO3 in 6.32 L of solution

Express your answer using two significant figures.

Answer :

Molarity = moles / volume of solution (L)

So molarity = 0.3 / 6.32 = 0.0474 Molar

2)

What is the net ionic equation of the reaction of MgSO4 with Ba(NO3)2?

Express you answer as a chemical equation including phases.

Answer :

MgSO4(aq) + Ba(NO3)2(aq) ---> Mg(NO3)2(aq) + BaSO4(s)

The net ionic equation is

Ba²⁺(aq) + SO4^2-(aq) ---> BaSO4(s)

3)

Part A

Enter the complete ionic equation to show the reaction of aqueous lead(II) nitrate with aqueous potassium sulfate to form solid lead(II) sulfate and aqueous potassium nitrate.

Express your answer as a chemical equation. Identify all of the phases in your answer.

Answer

Pb(NO₃)₂ (aq) + K₂SO4 (aq) --> Pb SO4 (s) + 2K NO₃ (aq)

Enter the net ionic equation to show the reaction of aqueous lead(II) nitrate with aqueous potassium sulfate to form solid lead(II) sulfate and aqueous potassium nitrate.

Express your answer as a chemical equation. Identify all of the phases in your answer.

Net ionic equation: Pb⁺² (aq) + SO₄^-2 (aq) --> PbSO₄(s)

4)

Part A

Write balanced molecular equation for the reaction between nitric acid and calcium hydroxide.

Express your answer as a chemical equation. Identify all of the phases in your answer.

2HNO₃(aq) + Ca(OH)₂ (aq) --> 2H₂O(l) + Ca(NO₃)₂ (aq)

Part B

Write net ionic equation for the reaction between nitric acid and calcium hydroxide.

Express your answer as a chemical equation. Identify all of the phases in your answer.

Net ionic equation will be

2H⁺ (aq) + 2OH^- (aq)--> H₂O(l)
