Many chemical reactions take place but the most noticeable one is the maillard browning reaction. The amino acids from the eggs combine with the reducing sugars when baked in the oven to produce melanoidins which are a brown pigment.
Another important reaction occurs due to the baking soda (sodium bicarbonate). When the cookies are baked the baking soda reacts with an acid ingredient to produce carbon dioxide, water and a sodium salt. The carbon dioxide causes the cookies to rise which is why this reaction is important.
This chemical reaction is called neutralization.
Baking cookies is a chemical change.
Cookies are complex mixtures; they have not a chemical formula, as a chemical compound.

Yes, baking homemade cookies involves converting chemical energy in the ingredients (flour, sugar, etc.) into thermal energy to make the cookies rise and become crispy or chewy.
The reactants and products need to be equal, as the supplies you put into the cookie mix has to be the same amount of cookies you get after.
Yes, yes it is.
B. Making cookies involves a chemical change because the ingredients undergo a chemical reaction during baking that results in the formation of a new substance with different properties (the cookies).
Making cookies is the only one which involves the making of a new substance, so that's the answer.
I got a chemical reaction in the science lab today.

It gives evidence of a chemical reaction because it's molecules have changed to make something new also because it looks very different from how it looked before.

when you eat wheatabix and jelly babies, they mix and explode to make a chemical reaction.
