calculus (point me in the right direction please?)
f'= 3x2 + 8x f'(5)= 3(25) + 8 (5)= =75+40=115 so u replace x by 5 in fx and u substract
calculate the pH of a 0.50 m solution of HCN. Ka for HCN is 4.9*10^-10 (The chemical equation for this.)
A ball whirls around in a vertical circle at the end of a string. The other end of the string is fixed at the center of the circle. Assume that the total energy of the ball-Earth system remains constant. (a) What is the tension in the string at the bottom? (Use the following a...
Thanks you Dr.Bob222. So the overall idea is that dissociation decreases molar mass and association does the opposite when a solute dissolves in a solvent. (How do you identify if either reaction occurs? Just wondering.)
So in this case, that a small amount of your unknown failed to dissolve in the t-butanol, it would effect the molar mass, just depending on the mass of both substances?
Lab on Determining hard water Not sure if I answered this currently, not completely sure how to explain either. If a student has a non-zero blank correction, but forgets to include that correction in his/her calculations:? a. Would his/her calculated [EDTA] be correct, too hi...
