Sodium metal reacts with aluminum chloride to produce sodium chloride and aluminum. the balanced reaction is: 3 na(s) + alcl3(aq) --> 3 nacl(aq) + al(s). how many moles of aluminum metal could you get when 12.0 grams of sodium react with excess aluminum chloride?

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
