<u>Answer:</u>
Vinegar is made from the fermentation of dilute alcoholic liquids into acetic acid.
<u>Explanation:</u>
Vinegar is a sour tasting liquid which is produced by the fermentation of dilute alcoholic liquids such as cider, wine and beer.
It is a solution of acetic acid which is more formally also known as ethanoic acid.
The concentration of acetic acid in vinegar is variable as it is used for different purposes with different concentrations.
Ethanol contains an alcohol group (-OH), which includes hydrogen bonding. Hydrogen bonding is stronger than other IMFs such as Van der Waals forces and Dipole-Dipole.
Ethene only has Van der Waals forces as it is an alkene with only C-H or C-C bonds. These means that the forces are not as strong.
Since ethanol contains hydrogen bonding, it will take a higher temperature in order to break these bonds, and thus results in a higher boiling point than ethene.
Answer:
Reactants: K = 2, S = 1, Co = 1, Cl = 2; Products: K = 2, S = 1, Co = 1, Cl = 2
Explanation:
The reaction is a double replacement reaction so the anions (Cl⁻ and S²⁻) switch places.
<u>1</u> K₂S + <u>1</u> CoCl₂ ⇒ <u>2</u> KCl + <u>1 </u>CoS (balanced chemical equation)
On the reactants and products side, K = 2, S = 1, Co = 1, and Cl = 2.
Hope that helps.
