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

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
