Tris(hydroxymethyl)aminomethane, commonly called or Trizma, is often used as a buffer in biochemical studies. Its buffering range is pH 7 to 9, and is for the aqueous reaction What is the optimal pH for buffers? pH = 8.1 Calculate the ratio at pH = 7.00 1 11.91 and at pH = 9.00. 83 10 (Simplify your answer completely.) A buffer is prepared by diluting 50.0 g base and 45.0 g hydrochloride (written as ) to a total volume of 2.0 L. What is the pH of this buffer? pH = What is the pH after 0.50 mL of 12 M is added to a 200.0-mL portion of the buffer?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
