a complete chemical analysis of a food would show that it is composed mostly of what
Not exactly but food, like any gas, liquid or solid, is made up of one or more chemicals. Plants growing is 'chemical change'. Food rotting is 'chemical change' Cooking food is 'chemical change'. Without 'chemical change' or chemical reactions, plants would not exist. Human beings would not exist. Anything we eat would not exist. Planet Earth would not exist!
Food digestions involve many chemical reactions.
Digesting food is a chemical change.
The teeth grinding is a mechanical change. The saliva mixing in with the food and starting the digestive process would be a chemical change.
Physical change because the two substances do not bond together. If you waited for a long time the water and the food coloring would separate.
CHEMICAL CHANGE
This is a chemical change. Pepsin catalyzes the chemical breakdown of food.
chemical
food is a chemical change if it is added with other components and turned into a form and if it is taken raw then it is not chemical change because no change is occuring
Metabolizing food is a chemical change because it converts food into energy.
Any modification in the chemical structure of foods is a chemical change.
Involving chemical reactions it is a chemical process.
