Wine goes bad soon after opening because Ethanol (CH3CH2OH) dissolved in it reacts with oxygen (O2) gas to form water and Aqueous Acetic acid (CH3COOH) The main ingredient of vinegar. Calculate the moles of water produced by the reaction of 0.060 mol of oxygen

Explanation:

Hello there!

In this case, since the chemical reaction between ethanol and oxygen to water and acetic acid is:

Thus, since there is a 1:1 mole ratio between oxygen and water, the produced moles of water are calculated down below:

Best regards!

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
