ok i got some help, apparently u use the cl concentration from hcl and the ksp and solve for Ag conc. which should be same as the molar solubility for in mol/l of AgCl then just convert. thanks for any help or good intentions.

so far all i can tell is that from the ph u get the concentration of HCL, then...im lost

[SOLVED] equilibirum and solubility product I need some help with this question, if there are any chemistry whizzes around id really appreciate it: Calculate the solubility of AgCl (in grams of AgCl/ L of solution) in an HCl solution having pH of 2.30. Ksp of silver chloride = 1.7 x 10^-10.

For an electrochemical cell containing two metals how do I figure out which one reduces and which one oxidizes using standard reduction potentials? Thank you very much for the help.

Well i have to do this experiment and took temperature measurements, even after the exercise my temperature kept rising and i needed an explanation for that. thanks for the help russ and moon.

I still need help, while we are exercising both internal and external temperatures are increasing. Directly after we stop which ones continue to increase and why?

k, thanks so i guess ideally i can safely say that during exercise both internal and external (fingertips) temperature increases and might increase slightly after exercise but not significantly?

Well apparrently when you stop exercising, your heart immediately slows down, decreasing the amount of blood pumped to your skin, so your temperature rises higher and you sweat more. And by external i do mean skin. Thanks. Any more help would be greatly appreciated.

Does anyone know what happens to the internal and external body temperature during and after exercise? I think that internal temperature increases during exercise and then continues to increase..Im not sure..

thanks thanks for the help, actually i just omitted the length and used energy equations, and i got the right answer...go figure..

Homework Statement Well i have a tiny question here a 2 kg mass starts at rest and slides down a 10 m high, 15 m long frictionless ramp. At the bottom of the ramp it reaches a flat surface where it hits and sticks to a stationary 3 kg mass . Find the final speed of the masses after...

Ya, you guys were right! Thank you so much! Solved!

i think we have to assume its going up

well the forces wrking in that direction are friction, the person pulling and the gravity so i would think that the net force would be Fpull - mgsin15 - Ff but the answer i get just doesn't workout thanks

[SOLVED] The NET FORCE and a lawnmower Homework Statement Well I am working on a question here and am finding trouble with one part. The answers are in brackets. The trouble I am having is with part c, where i believe you have to find the accleration then the time to work out power which is...
