Suppose a current of 250.mA is passed through an electroplating cell with an aqueous solution of Ag2SO4 in the cathode compartment for 52.0 seconds. Calculate the mass of pure silver deposited on a metal object made into the cathode of the cell.

Explanation:

The first step is to know what is the half-reaction of silver, so:

Therefore, the half-reaction is:

The next step is the calculation of the amount of charge, so:

Now, we can calculate the mass, we have to keep in mind that we have 1 mol of electrons for each mol of

2b2t

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
