Current annual energy consumption in the United States is 99.3 quads. Assume that all this energy is to be generated by burning CH4(g) in the form of natural gas. If the combustion of the CH4(g) were complete and 100% efficient, how many moles CH4(g) of would need to be combusted in order to provide the U.S. energy demand?
In order to neutralize a 2M HCL solution you could use a 2M NaOH solution. What will be the difference(if any) if you would use a 6M NaOH solution instead
which of the following accounts for the unusually high boiling point of water? the density of water, the hydrogen bonds in water
Equilibrium constant Kc for the reaction: H2 (g) + CO2 (g) - H2O (g) + CO (g) a) in one experiment, a container is introduced in a mixture formed by the four shown in the reaction gases.
The system CO2(g) + H2(g) *) H2O(g) + CO(g) is at equilibrium at some temperature. At equilibrium a 4.00 L vessel contains 1.00 mole CO2, 1.00 mole H2, 2.40 moles H2O, and 2.40 moles CO.
a 50.0 gram piece of iron at 152 degrees celsius is dropped into a 20.0 grams of water at 89 degrees celsius in an open
14 grams of water at 298 K are placed in an evacuated steel container whose volume is 10 L. If we assume that the volume of the liquid water may be ignored relative to the volume of the container, answer each of the following question
56.0 mL of a 1.20 M solution is diluted to a volume of 248 mL. A 124-mL portion of that solution is diluted using 157 mL of water. What is the final concentration?
Benzene has a heat of vaporization of 30.72;{{rm{kJ}}}/{{rm{mol}}} and a normal boiling point of 80.1 ^circ {rm{C}}. At what temperature does benzene boil when the external pressure is 420 torr?

The sample is placed in a drying dish (weight = 0.5000 g before the sample is added), and then placed in an oven at 104°C until all the moisture is evaporated
a) Assuming ideal behavior, what is the solubility of AgCl(s) in 1.00 x 10-4 M NaCl if only Ksp is considered? (b) What is the solubility AgCl(s) if all 4 equilibria are considered for the 1.00 x 10-4 M NaCl
