When you fry an egg it turns white and goes solid is this a chemical change and why?
No, it is a physical change. The proteins forming the substance of the egg "denature" above about 60 degrees Celsius. Proteins are complexly folded molecules and the vibration caused by the application of heat causes them to unravel - Once untraveled they tangle up to form a solid and the processes irreversible but because the change is a change in shape it is physical not chemical.
What else can I help you with?
Is this a chemical change or physical change silver nitrate solution is added to another solution producing a white solid?
it is a chemical change
Is frying an egg chemical or physical?
Frying an egg involves both chemical and physical changes. The heat from the pan causes the proteins in the egg white and yolk to denature and coagulate, which is a chemical change. The browning of the egg due to the Maillard reaction is also a chemical change, while the change in state of the egg from liquid to solid is a physical change.
Is the formation of a solid a chemical change?
Yes, if it occurs as the result of a chemical reaction. For example, if two clear colorless solutions form a white precipitate (solid) when mixed, that would be an example of a chemical change. The formation of a solid from freezing is a physical change.
When bromine reacts with sodium to form a white solid is it a physical or chemical change?
The reaction between bromine and sodium to form a white solid is a chemical change. This is because the atoms are rearranging to form new compounds with different properties, indicating a chemical reaction has occurred.
Does a physical or chemical change occur when aluminum foil is placed into liquid bromine and a white solid forms?
A chemical change occurs. When aluminum foil is placed in liquid bromine, the aluminum reacts with bromine to form aluminum bromide, which appears as a white solid. This reaction is a chemical change because the composition of the substances involved is altered.
Does cooking food causes chemical changes?
Protein becomes denatured at high temps- ie:egg turns to a solid white from clear
Is White phosphorous ignites easily a physical change?
Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.
When we place aluminium foil into liquid bromine and find a white solid is that chemical or physical property?
That would be a chemical property, specifically a chemical reaction. The formation of a white solid (aluminum bromide) indicates a chemical change has occurred as the aluminum has reacted with the bromine to form a new substance.
Why is there a chemical change when you roast a marshmallow?
There is a chemical change in a marshmallow when it is roasted because was once white and colder and than when it gets roasted it turns like a blackish-brown and burning hot.
Is it Chemical or Physical Frying an egg?
Frying an egg is a chemical change in which the protein in the egg white becomes denatured, which causes it to become white and solid. This condition is not reversible by physical means.
What is the color of zinc chloride when heated?
the chemical reaction is:Zn + 2 HCl = ZnCl2 + H2
Is chemical changes able to change?
No Chemical changes are not reversible. If you fry an egg, you will see the white change from a liquid to a solid. How ever, when you remove the egg from pan, the white does not change back to liquid on your plate. The substances present have reacted chemically preventing a physical change from occurring.
