5) Determine the unknown quantity: a. [ln-CsHs)W(CO)x]2 (has a W-W single bond) b. [(CO)3Ni-Co(CO)3]? C. [Ni(NO)=(SiMe3)] (all M-N-O are linear) d. [lnº-CsHs)Mn(CO)x]2 (has Mn=Mn double bond)
[Co(en)2(H2O)(Cl)]3[Ni(CN)4]2 For the nickel portion of the complex, determine the number of d electrons and given the possible geometry(s) would the complex be a high spin or low spin complex.
Given the half-cells: Ni/Ni+2 and Fe/Fe+2 Chose the anode and cathode. Calculate E° and ΔG° for this reaction. Calculate what the new cell potential (E) would be if the concentrations were [Ni+2] = 0.40 M and [Fe+2] = 0.30 M. Calculate how long you would have to run the battery at 6 amps to make the E drop by 0.03 volts, and calculate how many grams of anode you lose by that time. Using the equations: ΔG° = -nFE° ln...

1) I have 50.0 g of ethanol (C2H5OH) at 100 K. I want gaseous ethanol at 373 K. How much energy do I need to add? Please show steps! 2) Consider the following reaction for the combustion of natural gas (CH4): CH4(g) + 2 O2(g) → CO2+ 2 H2O ∆Hrxn= - 882 kJ/mol If I use this reaction as the source of heat in Question#1, how much methane would I need to burn to get my ethanol to 373 K?
