1) How much of a 3.56M NaOH solution would it take to completely react with 2.875 mL of a 1.32M MgCl2 solution? What is the theoretical yield of Mg(OH)2 (s) produced by this reaction?
2) What type of reaction is described in question 1? If you obtained 150.0 mg of Mg(OH)2(s) from the reaction, what is your percent yield?
If the combustion of this mixture releases 950.0 J of energy to what volume will the gases expand against a constant pressure of 650.0torr if all the energy of combustion is converted into work to push back the piston?
