Is yeast a chemical?
Actually, chemical change which results in a physical change. In the process of brewing, yeast converts sugar into carbon dioxide and alcohol, which is a chemical change. As a result, gas is emitted from the wort and the specific gravity (density) of the wort decreases, which are physical changes.
Is fermentation a chemical change?
Fermenting cheese will become a chemical change not a physical change.
What chemical can you use to decompose human waste out of an outhouse?
bakers yeast or rid-x !
What word is a gradual chemical change caused by yeast and bacteria?
You think probable to fermentation.
Which of the following microbial forms have the highest resistance to physical and chemical controls?
Bacterial endospores.
What is Yeast formula?
Yeast does not have a chemical formula. It is a living organism, not a chemical compound.
What is the chemical formula of yeast?
Yeast is not a chemical element, nor a compound, yeast is a living organism, a member of the Kingdom Fungi, this is eukaryotic microorganisms. They are generally unicellular organisms, but they can also form multicellular forms. They are useful for many processes human do because of the fermentation, which is the process that converts carbohydrates to carbon dioxide and alcohol.
What is the chemical formula for a pizza?
Hydrogen plus yeast equals air bubbles?
Is yeast physical science or chemical science?

The chemical formula for active dry yeast?
Yeast is not a chemical and has no chemical formula. Try looking at yeast as a single cell, similar to any single cell in your body. Those cells are made up of numerous types and classifications of chemicals. Some are very simple, like water. Others are extremely complex, like proteins. In the very complex protein molecules their chemical composition is only a small part of the functionality equation, since many chemicals might have the same ratios but the way they are put together and folded into three dimensional strucutures is what dictates their activities. If you are looking for the conversion of sugars to water and carbon dioxide the basic cycle is well known and established. I suggest you check out a basic organic or biochemistry book from your school library and read up on it.
