When hydrogen reacts with chlorine, the only product is hydrochloric acid. if 18g of hydrogen react completely with 633 g of chlorine, how many grams of hydrochloric acid are formed? (include units) 651 g when methane reacts with oxygen, the products are carbon dioxide (co2) and water (h2o). how many grams of water are formed if 24g of methane react completely with 96g of oxygen to form 66g of carbon dioxide? (include units)

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen

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.

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
