Barium Nitrate is a not very soluble nitrate. Calculate the Ksp (at 25 degrees) from the following ΔG's: Ba2+ = -561kj/mole NO3 1- = - 109kj/mole Ba(NO3)2 = - 797 kj/mole I did the first step and I ended up with dGrxn = -127 kj/mol. When I plugged it into the second e...
I am working on the same problem. I did the first step DrBob gave and I ended up with dGrxn = -127 kj/mol. When I plugged it into the second equation I got -127000/(-298)(8.314) = 51.2599. Then if I take the e of this I get 1.8x10^22. I feel like this is way off, since the opt...
Thank you! But how would i figure out the "??" I totally suck at chemistry!.. idk how to find the solubility ..?
Here is a following practice question on my study guide. i have no idea on how to do it. Any help would be appreciated! Thanks you. A solution contains 26.5g NaCl in 75.0g H2O at 20 degrees Celsius. Determine if the solution is saturated, unsaturated, or supersaturated. (The s...
i think you are missing some letyters to me it looks like the 1st one says christmas wreath the 2nd looks like it would be holy water
