You're provided with a bottle labled [CoCl2.6H2O] = 0.066 M in 4.60 M HCl. You heat a small volume of the solution in a hot water bath to 50 ∘C. If you determine that [CoCl42-] = 0.037 M at 50 ∘C at equilibrium, what must be the equilibrium concentration of [Cl-] at 50 ∘C? Express your response in units of M to three digits after the decimal.

Question 3 3 pts In Reaction 2, you added silver nitrate (AgNO3) to your solution of 1.0 M CoCl2. As mentioned in the lab procedure, silver nitrate dissociates in solution, yielding Agt and NO3. Silver I (Agt) loves chloride ions and will strongly bind to any that it can find. Upon binding with the chloride ions, a precipitate forms. Using your lab data to help you, answer the following questions below. + 4 CI...

Question 2 1 pts Suppose you are investigating the reaction: M(s) + 2 HCl(aq) → MCl2(aq) + H2(g). You weigh out a 0.202 gram piece of metal and combine it with 62.2 mL of 1.00 M HCl in a coffee-cup calorimeter. If the molar mass of the metal is 48.51 g/mol, and you measure that the reaction absorbed 111 J of heat, what is the enthalpy of this reaction in kJ per mole of limiting reactant? Enter your answer...
