How many moles chromium would be electroplated by passing a current of 5.2 A through a solution of Cr2(SO4)3 for 45.0 minutes Calculate the Eocell and AGO for the reaction 2Br-(ag) + F2(g) → Br2(1) + 2F-(ag) Given the following reduction potentials: Br2(1) + 2e- →2Br- (ag) Eo=1.06 V F2(g) + 2e- →2F- (aq) Eo = 2.87 V Is the reaction spontaneous 125.6 kl of heat are supplied to 0.5 kg of water at 22 oC. What is the final temperature of water? A sample of naturally occurring silicon consists Si-28 (amu = 27.9769), Si-29 (amu = 28.9765) and Si-30 (amu = 29.9738). If the atomic mass of silicon is 28.0855 and the natural abundance of Si-29 is 4.67%, what are the natural abundances of Si-28 and Si-30
