The short answer is yes.
It can be hard to define what exactly a chemical reaction involves but a key characteristic is that a new substance is created. A reaction may or may not be reversible and it may or may not involve a colour change. When you fry an egg, it is a chemical reaction. The fact that the egg white changes from colourless to white tips us off to this fact. What is actually happening is that the proteins in the egg white are being denatured. Next, the denatured egg whites bond together. As an analogy, this is rather like if you had 10 balls of yarn (wool) and you completely unravelled each of them (equivalent to denaturing the proteins). Next, you would tie together the ends of each of the lengths of yarn (equivalent to the denatured proteins bonding together). So the new substance created is a great big jumbled mess of long molecules that have bonded together to form even longer molecules.
Fertilized eggs undergo a great many chemical reactions as they develop into chickens. Unfertilized eggs don't undergo chemical reactions until such time as they are either cooked and eaten, or go bad and are thrown away.
Yes, it is, because a chemical reaction is occurring. In the case of dyeing eggs, the dye molecules are binding to the protein molecules in the egg shell, both directly, and via hydrogen bonds..
Cracking eggs is a physical change because it does not involve any chemical reactions. The eggshell breaking is a result of the physical force applied to it, rather than a change in the actual chemical makeup of the egg.
Yes, preparing custard involves a chemical change. When you heat the mixture of milk, eggs, and sugar, the proteins in the eggs coagulate, causing the mixture to thicken and change from a liquid to a semi-solid state. This transformation alters the chemical structure of the ingredients, making it irreversible, which is characteristic of a chemical change.
A chemical change occurs when preparing scrambled eggs due to the denaturation of proteins in the egg whites and yolks. When eggs are heated, the proteins unfold and recombine, resulting in a change in texture and structure. This transformation is irreversible; once cooked, the eggs cannot return to their original raw state. Additionally, the Maillard reaction may occur, contributing to flavor and color changes.

An eggs in not a reaction of any sort; it is an object.
Making eggs is a chemical change because it cannot be changed back to it's original form.
Adding baking powder to scrambled eggs is a chemical change because the baking powder reacts with the eggs to produce carbon dioxide gas, causing the eggs to become fluffier when cooked. This reaction alters the chemical composition of the eggs.

Cooking the eggs,because a solid is formed this is evidence of a chemical change... Hope that helps.

No, adding baking soda to scrambled eggs is a physical change. The baking soda simply interacts with the ingredients in the eggs, causing a physical reaction like bubbling or fizzing, but the chemical composition of the eggs themselves does not change.
Eggs would be considered a mixture. They are not elements themselves and they are not chemical compounds, but they are a mixture of various substances.
Irreversible changes are when a chemical reaction occurs and because of it the state of whatever your reacting cannot go back to its original form. Ex// making scrambled eggs. Once you've cooked the egg, you can no longer reverse the reaction and make it liquid once again.
Yes, it is a chemical change. It only takes one experience with a rotten egg to learn that they smell different that fresh eggs. When eggs and food spoil, they undergo a chemical change. The change in odor is a clue to the chemical change Chemical Reactions Chemical Changes are also called Chemical Reactions. Chemical reactions involve combining different substances. The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance. The same number of particles that exist before the reaction exist after the reaction.
