How would you cause a chemical change to vinegar?
For example adding a base.
Is mixing vinegar and baking soda a chemical or physical change and why?
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.
What is an exmaple of a chemical change?
A good example would be a reaction between vinegar and Baking soda. The 2 react to form a gas.
Is baking soda mixed iodine solution a chemical change?
Chemical, When something changes in color, it is a sign of a chemical change.
Would cornstarch and vinegar create a chemical reaction?
No.
Is cornstarch mixed with vinegar a chemical or physical change?
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.
What would cause a chemical change water?
Adding electric current to separate hydrogen from oxyge.
Is baking soda losing mass when heated a chemical or physical change?
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.
Is being resistant to corrosion a physical or chemical change?
Being resistant to corrosion is a physical property of a material, not a physical or chemical change. It means that the material does not undergo chemical reactions with its environment that would cause it to deteriorate over time.
Would baking soda and vinegar be considered a chemical reaction?
Yes.
What makes vinegar blow up?
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.
If the temperature of heptane increased from 90 degrees to 100 degrees would a physical or chemical change take place?
The temperature increase from 90 to 100 degrees for heptane would not cause a chemical change. It would only result in a physical change, such as a phase change from liquid to gas.
