Fuel is a mixture of different hydrocarbon compounds containing only hydrogen and oxygen. Calculate the volume of carbon dioxide, at 300 °C and 100 kPa, passing through a vehicle's exhaust during the combustion of a full tank of fuel (that is, 50 kg). To simplify the problem, assume that the formula for fuel is C7H16.
C7H16 + 11O2 ? 7CO2 + 8H2O
A fixed amount of gas at 25.0 °C occupies a volume of 9.23 L when the pressure is 629 torr. Use Charles's law to calculate the volume (L) the gas will occupy when the temperature is increased to 121 °C while maintaining the pressure at 629 torr.
A copper cathode with an initial mass of 10.77 g is placed in a solution of CuSO4. After current has passed through the electrode for 15.0 minutes the cathode has a mass of 12.89 grams. Determine the amount charge (in Coulombs) that has passed thr..
How many seconds are required to produce 1.0 g of silver metal by the electrolysis of a AgNO3 solution using a current of 30 amps?
