Afeed stream containing a mixture of 40% n-butane , 30% n-pentane and 30 % n- hexane flows into a flash unit. the flash temperature is 290 k and the flash pressure is 8.7 psi. what is the ratio of the exit vapor flow rate to the feed flow rate? what are the compositions of the exit streams? assume ideal mixture.

Describe the chemical reaction based on the chemical equation below. also, explain whether the equation is balanced.

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.
