How much energy in kilojoules is released when 26.5g of ethanol vapor (MM=46.07g/mol) at 93 degrees Celsius is cooled to -10 degrees Celsius. The boiling point of ethanol is 78.3 degrees Celsius. The molar heat capacities of ethanol vapor and liquid ethanol are 65.6K/K. mol and 112.3 J/K. mol respectively

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
