yes, a chemical change is anything that cannot be reversed, you cannot uncook an egg!
The proteins in the egg are denatured and crosslinked by the heat.
What else can I help you with?
When an egg is cooked is this a physical change?
Cooking an egg is a chemical change because it cannot be reversed.
What if you cooked the egg is it physical or a chemical change?
Cooking an egg is both a physical and chemical change. The physical change involves the transformation of the egg from a raw to a cooked state, while the chemical change occurs as proteins in the egg denature and coagulate due to heat. The overall process involves both physical and chemical transformations.
Is cooked noodles a physical or chemical change?
Both (assuming that they are egg noodles).
Why cant a cooked egg go back to raw?
Because as it is cooked it goes through a CHEMICAL change, not a physical change.
Is a cooked egg a chemical change?
yes, a chemical change is anything that cannot be reversed, you cannot uncook an egg! The proteins in the egg are denatured and crosslinked by the heat.
What evidence is there to show that a chemical reaction has taken place when an egg is cooked?
The change in color indicates that a chemical reaction has taken place.
Is a egg cooked a physical or chemical?
Depending on how you cook it it could be a little of both.
Is frying an egg a chemical or physical reaction?
Frying an egg is a chemical reaction because the heat changes the proteins and lipids in the egg, causing them to denature and form new compounds. This results in the cooked egg having different properties than when it was raw.
What is the difference between cooked and uncooked egg?
The difference between a cooked egg and a raw egg is that when a egg is cooked the clear/yellow gooey stuff turns white and turns into a solid. A raw egg doesn't have the white stuff because it has not been added to heat. This is an example of a chemical change.
Is scrambling an egg a physical or chemical change?
Scrambling an egg is considered a physical change because the eggs are still the same substance with the same chemical composition before and after cooking. The proteins in the egg are simply denatured and rearranged through the application of heat, without creating a new substance.
Why is it that the color of egg white is green?
The green color in egg whites is caused by a chemical reaction between sulfur compounds in the egg and iron in the eggshell. This reaction occurs when the egg is cooked for too long or at too high a temperature.
Why is a cooked egg a chemical reaction?
Because it is changing from it's original state and cannot be reversed. That is why you cannot reverse a cooked egg back into its normal state because it is a chemical change (cannot be reversed), but you can change a raw egg into another state.
