A leavening agent causes the baked good to rise by producing and/or trapping hot gas within the batter.

Carbon Dioxide.
yes, it has baking soda or baking powder, sometimes both. As these are chemical leaveners this makes a cookie a chemical property.
Chemical leaveners-- these are substances which when react to moisture or heat can produce gases -- the carbon dioxide gas -- they are used in quickbread as well as cakes and cookies. it is for immediate use unlike biological leaveners which used fermentation and take longer time. This usually combines the base chemicals and acid.Biological leavenersBiologocal leaveners -- are usually this process is longer than chemical leaveners as it used fermentation like the yeast --- it alters the biological chemistry of the batter or dough while the yeast is at work.An example of biological leavener is yeast leavening which "requires proofing, which allows the yeast time to reproduce and consume carbohydrates in the flour".Mechanical leavenersMechanical leaveners-- are what it is you used your hand by mixing leavening agents like whisking cream, egg whites or when you do creaming -- mixing butter with sugar. According to wikipedia usually this process "integrates tiny air bubbles into the mixture, since the sugar crystals physically cut through the structure of the fat. Creamed mixtures are usually further leavened by a chemical leavener and is often used in cookies.
A variety of baking supplies - called "leaveners" - make bread rise. Depending on the kind of bread and the type of recipe, one might use yeast, baking soda, or baking powder.
They are organised into categories. Those categories are: Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions External functions Cube functions
Biological leavening are microorganisms that release carbon dioxide as part of their lifecycle can be used to leaven products. Varieties of yeast are most often used. Other biological leaveners are beer, buttermilk, ginger beer, sourdough starter and yogurt.
There are infinitely many types of functions. For example: Discrete function, Continuous functions, Differentiable functions, Monotonic functions, Odd functions, Even functions, Invertible functions. Another way of classifying them gives: Logarithmic functions, Inverse functions, Algebraic functions, Trigonometric functions, Exponential functions, Hyperbolic functions.
Baking soda is not normally used to make bread; yeast or a sourdough/poolish are the leaveners. Quick bread (such as Irish soda bread) would generally require 1teaspoon baking soda.
They are both statistical functions.

You could not really classify formulas into types as the amount of formulas are infinite and you can have a variety of things happening in a formula. Functions come in categories, and that is maybe what you mean. It will depend on which version of Excel you have, but these are the categories available in later versions: Cube functions Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions
