In the fermentation of sucrose to ethanol, Calculate how many milliliters of CO2 (at STP) would be produced if all the sucrose were fully oxidized by aerobic respiration. with 10g of sucrose.

Consider the equilibrium system described by the chemical reaction below. At equilibrium, a sample of gas from the system is collected into a 5.00 L flask at 1200 K. The flask is found to contain 2.81 g of CH, 1.25 g of CO, 15.1 g of cO, and 25.3 g of H, What is the value of Kc for this reaction?   CH.(g) + CO,(9) = 2 CO(g) + 2 H,(g)

Imagine that a chemist puts 4.33 mol each of C3H8 and O₂ in a 1.00-L container at constant temperature of 505 °C. This reaction occurs: C3H8(g) + 502(g) 3C0₂(g) + 4H₂O(g) When equilibrium is reached, 0.645 mol of CO₂ is in the container. Find the value of Keq for the reaction.

While ethanol (CH₂CH₂OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene (CH₂CH₂) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 75 L tank with 17. mol of ethylene gas and 13. mol of water vapor. When the mixture has come to equilibrium he determines that it contains 7.9 mol of ethylene gas and 3.9 mol of water vapor. The engineer then adds another 3.3 mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is reached the second time. Round your answer to 2 significant digits. mol x10 Ś
