Wine goes bad soon after opening because the ethanoldissolved in it reacts with oxygengas to form water and aqueous acetic acid, the main ingredient in vinegar. Calculate the moles of water produced by the reaction ofof oxygen. Be sure your answer has a unit symbol, if necessary, and round it tosignificant digits.

1) Chemical reaction

CH3 CH2 OH + O2 ---> CH3COOH + H2O

It is balanced

2) Molar ratios

1 mol CH3 CH2OH : 1 mol O2 : 1 mol CH3COOH : 1 mol H2O

3) Conversion of 7.6 grams of ethanol to moles

Molar mass of CH3CH2OH = 2 * 12g/mol + 6 * 1 g/mol + 16 g/mol = 46 g/mol

moles = mass / molar mass = 7.6 g / 46g/mol = 0.165 mol

4) Use of proportions with the molar ratios:

1mol CH3CH2OH / 1mol O2 = 0.165 mol CH3CH2OH / x => x = 0.165 mol CH3CH2OH.

5)  Conversion of 0.165 mol O2 to grams

mass in grams = number of moles * molar mass = 0.165 mol * (2 * 16g/mol)

mass = 5.28 g ≈ 5.3 g

5.3 g

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

fe 55.85 g/mol and h2o 18.02 g/mol.
