When methanol, CH3OH, is burned in the presence of oxygen gas, O2, a large amount of heat energy is released, as shown in the combustion reaction. CH3OH(g)+32O2(g)⟶CO2(g)+2H2O(l)ΔH=− 764 kJ Based on the balanced thermochemical reaction, how much heat is produced when 39.9 g of methanol reacts with 61.9 g of oxygen? heat: kJ Which reactant is limiting? methanol oxygen

Tinererining 01: 57: 44 which statement correcte describes the actual veld and the theoretical yield of a reaction? textual vec is calculated to the reactant amounts but the theoretical yeld must be measured for each instance of a the actual vec is calculated from the amount of the limiting reactant and the theoretical yield is calculated from the 发公主 the actual weld depends on the reaction centers, but the theoretical yield and only with reactant amounts the actual vele represents the maximum weld possible and the theoretical yield assumes perfect reaction conditions save and ext e அட
