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)
Radio waves travel at the speed =3.00 108 m/s(speed of light,). if Saturn is 7.9 108 km from Earth then Determine how many minutes does it take for a radio message to reach Earth from Saturn?

Explain when 2.86 g of Na(s) react with excess F2(g) to form NaF(s) at standard state conditions, 69 .kJ of heat are evolved. Define what is the standard enthalpy of formation (H°f) of NaF(s)
A 21.496 g sample of magnesium is burned in air to form magnesium oxide and magnesium nitride. when the products are treated with water, 2.813 g of gaseous ammonia are generated.
How many grams of CaH2 (Molar Mass = 42.1 g/mol)are needed to generate 14.0 L of H2 gas if the pressure of H2 is 757 torr at 20.0°C
a 13.5 g piece of solid was heated to 98.8oc and dropped into a container with 45.0 g or water at 25oc. the final
Question- The answer to a post-lab question in Expt #10 indicates that the relative suspectibility of a hydrogen atom to chlorination was dependent on the degree of substitution at the carbon to which it was bound. Both the 1, 2- and 1, 3-dichloro..
Nitric oxide, NO, is made from the oxidation of NH3, and the reaction is represented by the equation: 4NH3 + 5O2 4NO + 6H2O
How many moles of H2 gas should be taken up by 1 octene in the course of this reaction. what volume does this correspond to at STP
if I weigh KHP to use in an experiment (to titrate with NaOH ) on a triple beam balance opposed to analytical scale to eventually find molar mass of unknown NH4 salt, what effect, if any, would this have on the accuracy of final results
