Then you need to balance the equation but don't forget you are only allowed 1 molecule of your product on the right hand side of the equation. You've been given these: C + O2 --> CO2 DH = -393 kJ/mol H2 + 1/2 O2 --> H2O DH = -286 kJ/mol C2H5OH + 3 O2 --> 2 CO2 + 3 H2O DH = -1368 kJ/mol Remember that if you double an equation, you multiply its DH by 2. How do you think about the answers? How long will the footprints on the moon last? Vous pouvez modifier vos choix à tout moment dans vos paramètres de vie privée. Alcoholic fermentation converts one mole of glucose into two moles of ethanol and two moles of carbon dioxide, producing two moles of ATP in the process. What scientific concept do you need to know in order to solve this problem? Carbon dioxide is produced in the gaseous state, water in the liquid state. Thanks for you help. Ghgyugugu. a. Relevance. Write a balanced chemical equation for the standard formation reaction of liquid ethanol C2H5OH? SOLUTION. What is the standard enthalpy of formation for ethanol #C_2H_5OH#? Spike.

How long can you keep a fresh turkey in the fridge before it has to be cooked? Thank you. Hence, the equation would be: 2 C(s) + 3 H2(g) + 0.5 O2(g) --> C2H5OH(l), Hence, the equation would be: 6 C(s) + 3 H2(g) --> C6H6(l), For the best answers, search on this site https://shorturl.im/avGNR, You know that the equation for the formation of ethanol from its elements is: 2 C + 3 H2 + 1/2 O2 --> C2H5OH. In this case, the reference forms of the constituent elements are O 2 (g) and graphite for carbon. Carbon dioxide is produced in the gaseous state, water in the liquid state.
