QUESTION:
Calculate the molarity of each solution.
a. 0.38 mol of LiNO3 in 6.14 L of solution

c. 12.87 mg KI in 112.4 mL of solution
ANSWER:Solution 54E: Here, we are going to write the molecular and net ionic equations for the given set of reactions and also identify the gas formed in each case. Step1: Net ionic equation shows only those chemical species which are taking part in a chemical reaction. while writing the ionic equation, we write out all the soluble compounds as ions and eliminate ions common to both the reactants and products. This will give us the net ionic equation. Step2: a) Hydrochloric acid reacts with nickel to give nickel chloride and hydrogen gas. The balanced molecular equation is given below: Ni(s) + 2HCl(aq) ---------> NiCl (aq) + H (g)2 2 From the rules of solubility, we can say that, HCland NiCl are water souble 2 compounds and will dissociate into ions in aqueous solution. So, the balanced ionic equation for the above reaction is: + - 2+ - Ni + 2H + 2Cl ---------> Ni + 2Cl + H 2 Eliminating the specta
