I need answer chemical analysis

4.) (30 points) a.) Write down all the reaction equations for nitrogen determination in meat b.) The protein content of meat products is approximately 6.25 times the N content. 3.818g of a meat sample is suitably acidified and calcined, and the released gas is absorbed in 100ml of 0.5NH2SO4 in a Kjeldahl apparatus. In back titration, 35mL of 0.4N NaOH is consumed. Find the protein percentage of the meat sample ( N:14gmol1). c.) What is the pH of the 0.1M(NH4)2SO4 solution? ( pKa=5.0 for NH3 ). 4.)
