chemical.
it digests substances chemically.
Initially the only change its location (physical). In the stomach, though, it starts to undergo chemical changes.
Digestion involves both physical and chemical changes. The teeth crush food into smaller particles, which is a physical change, whereas the saliva, stomach, gall bladder, and pancreas contain chemicals that break down food chemically in the mouth, stomach, and small intestines.
Yes, barfing is a physical change because it involves a change in state and appearance of food without altering its chemical composition. The food that is consumed undergoes physical changes as it comes back up from the stomach.
Yes it is a phisycal change because even though you cut the carrot in half its still a carrot. You're not changing the substence you are just changing what it looks like no cutting carrotis not a physical change no cutting carrotis not a physical change
A physical change could be easily described as a change that you can reverse. Melting an ice cube, than freezing it, etc. Eating is actually both because you chew the food and swallow it. After that your stomach's enzymes dissolves the food and readies it for your digestive system. :D
No. its chemical

No. Antacids neutralize the hydrochloric acid in the stomach. It is a chemical change.
No, it is a chemical change.
The reaction of an antacid with stomach acid is a chemical change. The antacid neutralizes the acid, forming a salt and water, which is a new substance different from the original reactants.
Its a chemical change. its like an acid reacting with a base to form salt and water.

It has both chemical and physical components Chewing, of course, is a physical process. Additionally enzymes in the saliva and stomach break down food chemically.
Digestion of any sort is actually a Chemical Change. For the enzymes in your stomach change the makeup of the substance to make it usable for the body.
The digestion of food through the alimentary canal involve a series of chemical and physical changes. In the example of pizza its bread component undergoes chemical changes as it is digested by amylase enzymes in saliva. Other chemical changes include hydrochloric acid of the stomach "attacking" and digesting proteins found in the pizza.
Its a chemical change.
