Current Attempt in Progress Batch combustion of 249kg of 2-butene (C4H3) and 964,1kg of oxygen (O2) proceeds to form carbon dioxide and water. Assume molecular weights of 56.106g/mol and 31.999g/mol for C4HB and O2, respectively. You may report intermediate results with the appropriote number of significant figures, but you should carry excess significant figures throughout the calculotion (ie. don't roundoff too early) to avoid pronagation of roundoft By how much is the other reactant in excess? Attempts: 0 of 3 used Amounts at Completion If the reaction below goes to completion provide the number of moles of ali components remaining and calculate the extent of reaction C4H6+6O24CO2+4H2O Assume the stoichiometric coefficients to have units of kmol. If the reaction proceeds to a 80.4% fractional conversion of cxygen, cakulate the number of moles of all components remaining and calculate the extent of reaction
