What is the ph of a solution prepared by mixing 50. 00 ml of 0. 10 mol l-1 methylamine, ch3nh2, with 20. 00 ml of 0. 10 mol l-1 methylammonium chloride, ch3nh3cl? assume that the volume of the solutions are additive and that kb = 3. 70 × 10-4 for methylamine.

Summarize the work of famous environmental scientists of the past.
