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.

∙ 13y agoOne of the main differences between a physical and chemical change is that in the latter heat is given off In frying an egg, heat is also accompanied, hence, it is a chemical change. Moreover, in chemical changes a new substance is formed as a new one is formed when an egg is fried. Chemical changes are usually irreversible; the fried egg cannot be reversed to its initial state and one of the prominent features of chemical change is that they cannot be separated by ordinary separation techniques. The fried egg and the oil cannot be separated by ordinary separation techniques. So, in short, frying an egg is a chemical reaction and the result is a chemical change.
Fried egg is a chemical reaction. The reason why the clear egg bit -albumin protein- changes colour to white on frying is because the protein is denatured above 40°C - as are all proteins. Denaturing means that the molecule's shape changes permanently and this changes the colour.
Incidently, all our body's enzymes are proteins. The reason why it is dangerous to have a temperature above 40°C is that our enzymes change shape irreversibly above this temperature and will not work. This process of the proteins changing shape irreversibly above 40°C is called being denatured.

∙ 13y agoFrying an egg changes it's chemical structure, so it is a chemical change. Physical change only includes change of state and similar processes that doesn't change the chemical structure of a substance.

What is the chemical reaction with eggs when they cook in cupcakes?
Eggs solidifies in cooking and forms the structure along with the proteins in flour.
Is cracking eggs physical or chemical?
It is physical, as no reaction happens when a shell is cracked.
Do eggs have a chemical reaction?
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.
Is dyeing eggs a chemical change?
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..
Is flour eggs and yeast to bread a physical or chemical change?
Flour eggs is physical and yeast to bread chemical
Is cooking eggs a chemical or a physical reaction?
chemical
Is an egg a chemical or physical reaction?
An eggs in not a reaction of any sort; it is an object.
Is making eggs a chemical change?
Making eggs is a chemical change because it cannot be changed back to it's original form.

Making scrambled eggs involves physical and chemical change. which step invovles a chemical change?
Cooking the eggs,because a solid is formed this is evidence of a chemical change... Hope that helps.
Describe the aeration in eggs and pastry like chemical reaction and panaray?
you shoot it with air and then boil it
Are eggs compounds or element or mixtures?
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.
What do you mean by unreversable changes?
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.
Is dyeing eggs a chemical change?
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..
Is food spoiling a chemical change?
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.
