3)(12 pts)a.Determine the oxidation numbers of all elements in each of the two formulas:H4P2O7H =1+P =5+O =2–MgS2O3Mg =2+S =2+O =2–(18 pts)Consider a sample of gas in a cylinder fitted with a moveable piston as shown. Thesample containsnmoles of gas at temperature T,pressure P, and volume V. The height ofthe piston ish.For each of the changes, select the answer from the following choices. 2 Fill in letter of answerAt constantT, the pressure on the piston isdecreasedby a factor of 4. At constantP, the number of moles of gas isdoubledand the temperature isdecreasedby a factor of 2. At constantT, the pressure on the piston isdecreasedby a factor of 2._______ At constantP, the temperature isincreasedby a factor of 4._______ At constantP, the number of moles of gas iscut in halfand the temperature isdecreasedby a factor of 2. _______
