Calculate the moles of water produced by the reaction of of ethanol. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answer 1

The question incomplete. complete question is :

Wine goes bad soon after opening because the ethanol $CH_3CH_2OH$ dissolved in it reacts with oxygen $O_2$gas to form water and aqueous acetic acid $CH_3COOH$, the main ingredient in vinegar.  Calculate the moles of water produced by the reaction of 1.2 mol of ethanol. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.

Answer:

1.2 moles of water produced by the reaction of of ethanol.

Explanation:

The reaction of ethanol with oxygen is given by :

$CH_3CH_2OH + O_2\rightarrow CH_3COOH + H_2O$

Moles of ethanol = 1.2 mol

According to reaction, 1 mole of ethanol is gives from 1 mole of water.

Then 1.2 mole of ethanol will give :

$\frac{1}{1}\times 1.2 mol=1.2mol$ of water

1.2 moles of water produced by the reaction of of ethanol.
