Consider the image below depicting an ideal gas contained within a 4.5 L 4.5 L cylinder under a constant force. If 3.0 × 10 − 3 moles 3.0×10−3 moles of gas are occupying the cylinder and the temperature of the gas is 350 K 350 K, determine the mass of the weight on the cylinder. Assume the top of the cylinder has an area of 1.0 m 2 1.0 m2, and atmospheric pressure can be ignored.

What is the value of keq for the reaction expressed in scientific notation?

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.
