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

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
