Fermentation is a chemical process.
Chemical activity increases as you move upward in the group. Chlorine gas and chlorine compounds have been used as chemical weapons
Chemical changes are certainly part of what is happening.
Austin Craig is a man whoreee !!
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
This is a chemical change.
Crepes are a type of food - not a physical or chemical change. What's happening to the crepe? Is it burning? Is it torn apart? Is it decomposing? You didn't indicate what is happening to the crepe that would be a chemical or physical change. This question is kind of like asking "Is the water freezing or evaporating?" Well, that depends on what's happening to the water.

The ability of a substance to undergo a chemical change is called the Chemical activity of a substance.
Cooking is for example a chemical change.
"chemical" usually secondary to biologic activity.
A physical and Chemical change.
Fermentation is a chemical process.
It is primarily a chemical change. However, physical changes also occur because of the chemical activity.
There are two kinds of changes - physical and chemical. It depends on how the change is made.
when milk curs it is a chemical change. A physical change is change in form, which is revesrable. Like water being frozen then thawed. A chemical change is irreversible, and involves a change in the chemical make up. What is happening is a new compound is being formed by the milk reacting with the air and such.
