The main chemical formula in bread is C6H12O6, which represents glucose, a simple sugar. Additionally, bread also contains other macromolecules such as starch (C6H10O5)n and proteins (various amino acids), which contribute to its structure and nutritional content.
The chemical is calcium propionate, with the formula Ca(C3H5O2)2. It is an ionic compound with four ions per formula unit, containing the polyatomic cation Ca2+ and the anion C3H5O2-, and it is commonly used as a preservative in bread-making.
No, slicing bread is a physical change. The act of cutting the bread into smaller pieces does not alter its chemical composition.
Toast itself does not have a unique chemical formula as it is a product resulting from the browning of bread when exposed to heat. The chemical composition of toast would mainly consist of the same components found in bread, such as carbohydrates, proteins, and water, with some additional compounds formed during the toasting process, like Maillard reaction products.
Toasting bread is a chemical change because the heat causes a reaction in the starches and sugars present in the bread, resulting in a new substance with different properties than the original bread.
Physical
Despite the huge amount of chemicals put into modern bread there is no move yet to call bread a chemical. Thus it has no specific chemical formula. Bread is mostly comprised of starch and cellulose, both of which are massive molecular constructs of basic sugars. Thus bread is mainly Carbon, Hydrogen and Oxygen.

No, slicing bread is a physical change. The act of cutting the bread into smaller pieces does not alter its chemical composition.
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
No because it is not changing the chemical structure of the bread
Yes, the preparation of bread is a chemical process.

Slicing bread is a physical change because it does not change the chemical composition of the bread.
Energy has no chemical formula as it is not a chemical.
chemical
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
Yes because it is a chemical reaction and these reactions are irreversible
