- What characterizes an electrolytic cell? What is an ampere? When the current applied to an electrolytic cell is multiplied by the time in seconds, what quantity is determined? How is this quantity converted to moles of electrons required? How are moles of electrons required converted to moles of metal plated out? What does plating mean? How do you predict the cathode and the anode half-reactions in an electrolytic cell? Why is the electrolysis of molten salts much easier to predict in terms of what occurs at the anode and cathode than the electrolysis of aqueous dissolved salts?

- For the following reaction, calculate the value of Q. 3A - 4B + 2C 1 [A] 0.42 [B] = 0.82 [C] = 0.90 To avoid possible rounding errors report your answer to three significant figures. On your scrap paper you should report the proper number of significant figures if correct answer has more or less than three.The compound diborane (B2H6) was at one time considered for use as a rocket fuel. Its combustion reaction is B2H6(g) + 3 O2(l) → 2 HBO2(g) + 2 H2O(l) The fact that HBO2, a reactive compound, was produced rather than the relatively inert B2O3 was a factor in the discontinuation of the investigation of the diborane as a fuel. What mass of liquid oxygen (LOX) would be needed to burn 234.4 g of B2H6? Answer in units of g.Calculate AH for the reaction, N2H4(1) + O2(g) -----> N2(g) + 2H2O(1), from the following data: 2NH3(g) = 3N20(g) -----> 4N2(g) + 3H2O(1) N20(g) = 3H2(g) 2NH3(g0 + 1/2O2(g) -----> N2H4(1) + H2O(1) H2(g) + 1/2O2(g) AH = -1010 KJ -----> N2H4(1) + H2O(1) AH = -317 KJ AH = -143 KJ %3D -----> H2O(1) AH = -286 KJA chemist fills a reaction vessel with 3.61 atm nitrogen (N,) gas, 8.64 atm oxygen (0,) gas, and 6.55 atm nitrogen monoxide (NO) gas at a temperature of 25.0° C.
