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!
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
True. Food contains chemical energy in the form of molecules that can be broken down during digestion to release energy for the body to use.
false
because its texture and color became different than its true colcr!
Not true, they are not similar; a chemical change is a change in the molecule, the physical change is not.
True because when you mix chloride and sodium you get a chemical change, which in turn creates a new substance.
No it is not, as the ice will still retain its chemical properties. This is an example of a physical change. Remember that the indicators of a chemical change are a change in colour, a change in odour, a change in temperature, the formation of a precipitate, or a gas being given off.
chemical change
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
A change in color
A physical change is when something changes to a different state (solid, liquid or gas), but it does not change chemical composition; for example, it remains H2O. In a chemical change, new chemical bonds are formed.
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
