An electrical resistor immersed in a liquid produces 65.0 W of electrical energy for 120 seconds, which heats the 0.780 kg
mass of liquid, causing it to rise in temperature from 18.55°C to
22.54°С. Find the average specific heat capacity of the liquid in
this temperature range. Assume that negligible heat is
transferred to the container that holds the liquid and that no heat
is lost to the surroundings.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
