For each of the trials you performed, and in the same sequence as you entered the volumes of standardized Na2S2O3 required to reach the endpoint, how many moles of 10, were present in your samples? Report 3 significant figures, e. g.0.0000562. moles(IO3) # of Trials V(Na2S203) Trial 1: 6.20 Trial 2: 6.20Part IV. For each of the trials you performed, what volume in mL of standardized Na2S2O3 was required to reach the endpoint?

Given sno2 + 2h2 - sn + 2h20 tin oxide reacts with hydrogen to produce tin and water. how many moles of sno2 are needed to produce 500.0 grams of sn?

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.
