C2H5O + O2 --> 2CO2 + H2O. The easiest way is to set up the reaction equation without any coefficients: Now start balancing, first with carbon, then with hydrogen and last the oxygen. Write a balanced chemical equation for this reaction. Include states-of-matter under the given conditions in your answer. In many cases a complete equation will be suggested. One the product side the only compound with carbon is CO2. The only H on the product side are in H2O, so you need 2.5 H2O. Compound states [like (s) (aq) or (g)] are not required. C2H5OH(l) + 3 O2(g) -> 2 CO2(g) + 3 H2O(g) During an experiment 10.00 g of ethanol is completely burned in air to release CO2(g) and H2O(g) as shown in the equation above. Interpret the equation in terms of numbers of molecules and moles. Gasohol is a mixture of ethanol and gasoline.C2H5OH (l) + O2 (g) CO2 (g) + H2O (g)Balance the equation. By using this website, you signify your acceptance of, calcium hydroxide + carbon dioxide = calcium carbonate + water, Enter an equation of a chemical reaction and click 'Balance'. C_3H_8 + 5O_2 -> 3CO_2 + 4H_2O We have: C_3H_8 + O_2 -> CO_2 + H_2O I would always start by balancing the elements that only occur once on each side. C_3H_8 + O_2 … Select the equations that represent chemical reactions, rather than physical changes I. CH4 (g) + O2 -> CO2 (g) + H2O (g) This shows you that for every mole of ethanol, you will get 3 moles of water.  So if you start with 0.51 moles of ethanol, you will produce 3 x .51 or 1.53 moles of water.
