Wine goes bad soon after opening because the ethanol dissolved in it reacts with oxygen gas to form water and aqueous acetic acid , the main ingredient in vinegar. 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.

The question incomplete. complete question is :

Wine goes bad soon after opening because the ethanol dissolved in it reacts with oxygen gas to form water and aqueous acetic acid , 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.

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

Explanation:

The reaction of ethanol with oxygen is given by :

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 :

of water

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

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
