Use the problem below to answer the question: how many grams of h2 would be formed if 34 grams of carbon reacted with an unlimited amount of h2o? the reaction is: c + h2o → co + h2 the equation is balanced. the starting substance is carbon, c. the ending substance is hydrogen, h2. using the periodic table, find the molecular mass of h2. h2 = g/mole

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.
