Wine goes bad soon after opening because the ethanol (CH3CH2OH) dissolved in it reacts with oxygen (O2) gas to form water and aqueous acetic acid (CH3COOH), the main ingredient in vinegar. Calculate the moles of oxygen needed to produce 0.090mol of water. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits. Compound A reacts with Compound B to form only one product, Compound C, and it's known the usual percent yield of C in this reaction is 88.%. Suppose 5.5g of A are reacted with excess Compound B, and 12.8g of Compound C are successfully isolated at the end of the reaction. Liquid hexane (CH3(CH2)4CH3) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). What is the theoretical yield of water formed from the reaction of 23.3g of hexane and 140. g of oxygen gas? Be sure your answer has the correct number of significant digits in it
