Solar energy has been suggested as a source of renewable energy. If, in the desert direct radiation from the sun (save for 320 days) is 975 W per m2 between 10 AM and 3 PM, and the conversion efficiency to electricity is 21%, how many square meters are needed to collect an amount of energy equal to annual US energy consumption of 100 quadrillion BTUs? Is this construction feasible? How many pounds of coal (of heating value of 10,000 BTUs per pound) would be needed to provide the 100 quadrillion BTUs if the efficiency of conversion to electricity was 35%? What fraction of the US coal reserves (estimated at 250 billion short tons) is the calculated quantity?
When 100.g Mg3N2 reacts with 75.0 g H2O, 15.0 g of NH3 is formed. What is the % yield?

If the partial pressure of the cyclopropane in the mixture is 330 mm Hg and the partial pressure of the oxygen is 1.0 atm, what is the total pressure of the mixture in torr
The calcium in a second 10.00-mL aliquot was isolated as CaC2O4(s) redissolved in acid, and titrated with 12.21 mL of the EDTA solution. Assuming that 15 to 300 mg of magnesium and 50 to 400 mg calcium per day are normal, did this specimen fall wi..

A 4.70 g nugget of pure gold absorbed 278 J of heat. The initial temperature was 28.0°C. What was the final temperature.
what is the balanced chemical reaction describing the decomposition of ammonium nitrate, and calculate the standard heat of reaction using the appropriate enthalpies of formation
The decomposition of dimethyl ether (CH3OCH3) to methane, carbon monoxide, and hydrogen gases is found to be first-order.
In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together).
