In the chemical reaction below, sodium (na) and chlorine (cl) combine to form sodium chloride (nacl). 2na + cl2 → 2nacl if the combined mass of the starting reactants is 50 grams, then the mass of sodium chloride formed once the reaction has reached completion a. will be exactly 50 grams. b. will be less than 50 grams. c. will be exactly 100 grams. d. will be between 50 and 100 grams.

What is the mass of sodium in 3 moles of sodium chloride

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.
