CASE STUDY: In July 1983, an Air Canada Boeing 767 ran out of fuel over central Canada on a trip from Montreal to Edmonton. (The plane glided safely to a landing at an abandoned airstrip.) The pilots knew that 22,300 kg of fuel was required for the trip, and they knew that 7682 L of fuel was already in the tank. The ground crew added 4916 L of fuel, which was only about one fourth of what was required.
The crew members used a factor of 1.77 for the fuel density-the problem is that 1.77 has units of pounds per liter and not kilograms per liter! What is the fuel density in units of kg/L? What mass and what volume of fuel should have been loaded? (1 lb = 453.6 g)
Compute the solubility of silver sulfite, Ag 2 SO 3 in units of grams per liter and complete and balance these given redox equations by the half reactions method (the oxidation reaction and the reduction reaction)
