Whether they give off a sweet smell or not, baking is a chemical change. Can you separate the egg, the flour, the sugar? No, then it is a chemical change.

Decomposition of any compound e.g. when heated CaCO3 compound decomposes to CaO and CO2 compounds, gives different substances and hence a chemical change. Y.Ozkalay

What chemical baking change cookies has?
Assuming that the cookies have flour, eggs, sugar, and a touch of baking soda or baking powder. The heat will: > Cause the protein in the eggs to firm up ( it is much like polymerization of a plastic), This is what holds the cookie together > The sugar and starch will react with oxygen in the air...this is what gives the cookie a brown color ( too much oxidation and you have burnt cookies!) The baking powder or baking soda ( depending on recipe) will cause the cookie to rise by releasing carbon dioxide....the same gas in soda. Baking soda will need something acidic (tart tasting = acidic) to start the reaction..like buttermilk. Baking powder only needs the presence of a liquid. Double acting baking powder releases carbon dioxide when it comes in contact with a liquid and then again when exposed to heat. A little thought about this will indicate that if you let a batch of cookie dough sit around all (or at least most) of the carbon dioxide will work its way out and you will have flatter cookies than if you made them right away.
If Lori gives Cameron 5 cookies he will have 3 times as many cookies as Lori If Cameron gives Lori 5 cookies they will have the same number of cookies How many cookies do they each have?
They each have ten. If Lori gives Cameron five cookies he will have 15 and she will have five. Then if he gives her five cookies they will each have ten again.

Is baking powder better for baking?
One is not better than the other. Baking soda will make the cookies crisper, and make them rise more. Baking powder will make them softer. Take your pick. I baked cookies with baking soda and it made the cookies look more like sticky bread than cookies. You absolutely can NOT use baking soda at all. Baking powder is for cookies, baking soda is for stuff you want to rise (like bread). The answer above is false.
Why do they put salt sometimes in cookies?
Cookies need salt for a couple of reasons. First and foremost, taste. Salt brings out and enhances the flavor of baked goods, and actually improves them. Ever wondered why people love salted caramel and salted chocolate? It makes them taste even better. As far as the chemical baking process goes, salt also helps in the process of gluten formation, the process whereby cookies have a stable structure and don't crumble apart.
