Can you plz answer all the questions

Thanks

A student is asked to design a simple calorimetry experiment to determine the molar enthalpy of combustion for methanol, using the set up shown below. The molar enthalpy of combustion for methanol in an open system is 637.9k/mol The molar enthalpy of combustion for methanol in an open system is -637.9 kJ/mol. If she uses 495.0 mL of water and wishes to have the temperature of the water increase by 22.50C during her experiment, what mass of methanol should she plan to burn? Answer in grams to two decimal places. You are asked to determine the molar enthalpy of neutralization of sodium hydroxide and are provided the following set up. NaOH(aq) H, SO.(aq) List the measurements you would need to make while completing this experiment to determine the molar enthalpy of neutralization. What products will be made in the electrolysis of an aqueous solution of lead(11) fluoride? Pb(s), F2(g) H2(g). O2(9) Pb(s), O2(g), H(aq) F2(g), H2(g), OH (aq) What is the electrical potential required for the electrolysis of an aqueous solution of calcium fluoride? Answer to two decimal places.
