How many coulombs (C) of electrical charge must pass through an electrolytic cell to reduce 0.44 mol Ca2+ ion to calcium metal? Use F=96500

A galvanic cell at a temperature of 25.0 °C is powered by the following redox reaction: Cu²* (ag)+ Zn (s) –→ Cu (s) + Zn²* (ag) 2+ 2+ Suppose the cell is prepared with 7.28 M Cu²" in one half-cell and 7.67 M Zn²™ in the other. Calculate the cell voltage under these conditions. Round your answer to 3 significant digits. x10 믐

Question 4: (a) What are redox reactions? Explain the difference between a gal- vanic and an electrolytic cell. Consider the cell described below: Al | AP"(1.00M) | Pb³"(1.00M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al"] to have changed by 0.60 mol/L. (Assume T = 25°C.) (b) Many elements have been synthesized by bombarding relatively heavy atoms with high-energy particles in particle accelerators. Complete the fol- lowing nuclear equations, which have been used to synthesize elements. U + C-→ Cf + Cf + 'B Lr + + He Bk + in + 6 n 10 Db + 4 in 103

You make a voltaic cell with copper and aluminum. If the cell potential is measured to be +2.50 V at room temperature, then what is the reaction quotient?
