An industrial process makes calcium oxide by decomposing calcium carbonate. which of the following is not needed to calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate?

a. the balanced chemical equation

b. molar masses of the reactants

c. molar masses of the product

d. the volume of the unknown mass

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.
