Wine goes bad soon after opening because the ethanol (ch, ch, oh) in it reacts with oxygen gas (0.) from the air to form water (110) and acetic acid (ch, cooh), the main ingredient of vinegar. what mass of water is produced by the reaction of 4.59 g of ethanol be sure your answer has the correct number of significant digits.

The mass of water produced is 1.8 grams

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of ethanol = 4.59 g

Molar mass of ethanol = 46.07 g/mol

Putting values in equation 1, we get:

The chemical equation for the reaction of ethanol with oxygen gas follows:

By Stoichiometry of the reaction;

1 mole of ethanol produces 1 mole of water.

So, 0.0996 moles of ethanol will produce = of water.

Now, calculating the mass of water from equation 1, we get:

Molar mass of water = 18 g/mol

Moles of water = 0.0996 moles

Putting values in equation 1, we get:

Hence, the mass of water produced is 1.8 grams

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
