oxidation product for 3-methyl-1-heptanol
Hello, I do apologize DrBob222 I didn't see your post from yesterday. However, thank you for help and thank you devron for your help as well. The extra credit only says how would prepare a .6m acetate buffer with a pH = 4.0. So I too, wasn't sure what the question was ...
How to start these problems out: Please help thank you Use the Henderson-Hasselbach equation: pH = pKa + log [A-]/[AH], where A- is the conjugate base and AH is the weak acid. Calculate the pH of an acetate buffer in which the acetate concentration [CH3COO-] is 3.5 times great...

Suppose the Eskimo is pushing the same 50.0-kg sled across level terrain with a force of 51.5 N. If he does 3.85 102 J of work on the sled while exerting the force horizontally, through what distance must he have pushed it?
An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of + 14.2 m/s and measures a time of 22.2 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due ...
