Add baking soda (watch out, it will fizz.)
For example adding a base.
Chemical. Vinegar is acidic - bicarniate when acidified produces carbon dioxide which bubbles out. This is a chemical change because the end-products (carbon dioxide, sodium acetate) are different species than the reactants (sodium bicarbonate, acetic acid). It is impossible to regain the initial state without the addition of new chemicals into the system. A physical change would be the freezing of vinegar. The reactants and the products are the same species (vinegar), and the initial state (liquid) can be regained by allowing the frozen vinegar to thaw.
If you are looking for what makes the vinegar fizz, baking soda or another base would work. It works because the vinegar and baking soda cause a chemical reaction with each other, and they cause it to fizz and foam. So in short, baking soda would cause it to "blow up." If you were looking for a different answer, I really don't know.
A good example would be a reaction between vinegar and Baking soda. The 2 react to form a gas.
No.
Kind of tricky question, because on the surface, one might not think that cornstarch and vinegar (acetic acid) don't react chemically. But, in fact, there can be a chemical reaction under the right conditions. So, it would probably be safe to say "chemical" change, if given the chance, but it could also be just a physical change if conditions aren't right.
Fermentation is a chemical change, as new substances, alcohol and carbon dioxide are produced. It would be extremely unlikely that leaving a glass of grape juice to ferment would produce a drinkable wine. Further oxidation to vinegar would be almost inevitable.
mixing baking soda with water is a physical change b/c you don't change the chemical structure mixing baking soda with vinegar is a chemical change b/c you change the chemical structure ================= It is definitely a chemical reaction resulting in a chemical change.
Adding electric current to separate hydrogen from oxyge.
Electrolysis of water is a chemical change. Exposing sodium chloride to sunlight would cause some heating, but no chemical changes.
Yes.
some chemical properties of vinegar would be it is transparent flammable but not explosive reactive does not rust so those are just a few but i hope they help.
