Consider the following equilibrium:
o2(g)+ 2f2(g) ↔ 2of2(g); kp = 2.3×10-15

which of the following statements is true?

a. if the reaction mixture initially contains only of2(g), then at equilibrium, the reaction mixture will consist of essentially only o2(g) and f2(g).
b. for this equilibrium, kc=kp.
c. if the reaction mixture initially contains only of2(g), then the total pressure at equilibrium will be less than the total initial pressure.
d. if the reaciton mixture initially contains only o2(g) and f2(g), then at equilibrium, the reaction mixture will consist of essentially only of2(g).
e. if the reaction mixture initially contains only o2(g) and f2(g), then the total pressure at equilibrium will be greater than the total initail pressure.

Find the number of grams of hcl needed to react completely with .50 moles of magnesium.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced. be sure your answer has the correct number of significant digits.
