Calculate the number of moles of Co^+2 are there in the equation Co(H2O)6^+2 +4Cl <--> CoCl4^-2 +6H2O? I had found in the previous question the number of moles of CoCl2*6H2O and I'm not sure but I believe the moles of CoCl2*6H2O are the same as CO^+2.

f(x)=((6x-3)/(x+6)) how do you find the intervals of decreasing and increasing...I found that there were no critical points yet I was also correct that the function increased (-I,-6) and (-6,I). I was wrong that there were no decreasing intervals though.

I found that it came to 6.30 for the pH. So I first balanced the equation set up an "ICE" box and then solved for x using the Ka equation...Ka=([H+][A-])/([HA]), I neglected the +x and -X and plugged in to solve. Then I got the pH by doing the negative lo...
