This is the ultimate in weak acid base type problems, including tips on how to calculate pH, Ka, Kb, for simple monoprotic acids as well as for diprotic acids.

Generic weak acid base equilibria, with examples of numbers given, as well as diprotic acid example.

Only for 103139,103997, 103866, 103940, or 103642 only

I need the names of: a)[Cu(NH3)4]SO4*H2O b)[Co(NH3)5H2O]Cl 3 c) [Co(NH3)5Cl]Cl 2 d) [Ni(NH3)2Cl 2]

pH titration curve (the equivalence point)

What's the pH at the first equivalence point of 0.100M of malonic acid of 25mL with 0.140M of NaOH? What's the pH after 25mL of NaOH were added?

pH Titration Curve (equivalence point)

What's the pH of 0.10M of malonic acid of 25mL with 0.140M of NaOH? What's the pH after 25mL of NaOH were added?

acid base equilibria

Please show all work and remember this is a first year course. Chem is my weakest subject. Please send responsse in Word. Also, if you are not willing to show me the proper way to do these by showing the calculations and will only supply me with some notes that I could read out of any textbook myself, please do not take this pos ...continues

thermodynamics problems

These problems have already been answered to the best of my ability I just want to double check my answers becasue I absolutely have to get an A on the upcoming quiz.

octane rating

Explain what a gasoline octane rating means. Please draw chemical structures to suport your answer.

Associated environmental problems

For each of the following sources of energy, name one associated environmental problem: solar, wind, biomass, geothermal

Ozone and uv radiation

Ozone near the earth's surface is considered a pollutant, yet we need it in the stratosphere to protect us from uv radiation. Explain this seeming contradiction.

Nuclear fusion and fission

Nuclear fusion offers the promise of unlimited energy to mankind. How is fusion different from fission? Where do on-going fusion reactions occur? Is the development of fusion as an energy source worth the risk? What are the risks? This is the second time this question has been posted as the first response was incomplete.
