When Methanol is burned in presence of O2, large amount of heat energy is released:

CH3OH(g) + 3/2O2(g) —> 2H2O(l) to produce -764kJ of heat

Based on the balanced reaction, how much heat is produced when 40.4g of methanol reacts with 62.6g of oxygen? Which reactant is limiting?

An alkaline battery produces electrical energy according to the following equation. zn(s) + 2 mno2(s) + h2o(l) zn(oh)2(s) + mn2o3(s) (a) determine the limiting reactant if 17.5 g zn and 31.0 g mno2 are used. (type your answer using the format ch4 for ch4.) (b) determine the mass of zn(oh)2 produced. _ g

Calculate the mass of carbon in 97.0 g of sucrose c12h22o11

About 3% of the water on earth is freshest. only about 40% of that freshwater is available for human use. why is so much freshwater unavailable for human use?
