Answer 1

1.

Vinegar is not a pure substance and so has no chemical formula. Vinegar is mainly water (H2O), but makes vinegar acidic (and gives it its smell) is acetic acid, which has formula CH3COOH. Vinegar is usually only about 4-8% acetic acid.
vinegar is a liquid produced by the fermentation of alcohol into acetic acid and other fermentation by-products. The acetic acid concentration ranges typically from 4 to 8 percent by volume for table vinegar (typically 5%) and higher concentrations for pickling (up to 18%) although in some countries the minimum strength may be less. Natural vinegars also contain smaller amounts of tartaric acid, citric acid, and other acids.
