Problem 6.144
A 2.197 g sample of an unknown alkaline-earth metal was allowed to react with a volume of chlorine gas that contains 1.91×1022Cl2 molecules. The resulting metal chloride was analyzed for chlorine by dissolving a 0.623 g sample in water and adding an excess of AgNO3(aq) to give a precipitate of 1.126 g of solid AgCl.
A
What is the percent Cl in the alkaline-earth chloride? = 44.7%
What is the identity of the alkaline-earth metal? = Sr
*Write balanced equation for first chemical reaction.
Express your answer as a chemical equation. Identify all of the phases in your answer.
Homework Answers

A 1.268 g sample of an alkaline earth metal carbonate, MCO3 was treated with 100.00 mL of 0.2166 M HNO3, as shown in the reaction below. After the reaction, it was determined that 8.809 × 10－3 moles of HNO3 remained in solution. Given this information, what is the identity of the metal M? Show all of your work. MCO3(s) + 2HNO3(aq) → M(NO3)2(aq) + CO2(g) + H2O(l)
