Is mixing red and yellow paint to make orange a chemical or physical change?

Mixing red and yellow paint to make orange is a physical change because no new substances are formed. The individual red and yellow paint molecules are simply being physically combined to create a new color.


When two clear liquids are mixed and a yellow color forms is it a chemical change?

Yes, if two clear liquids are mixed and a yellow color forms, it is likely a chemical change. A color change is often an indicator of a chemical reaction taking place, indicating that new substances with different properties are being formed.


Is a salt forming a chemical change or physical change?

It is a chemical change because the sodium(Na) is a liquid that forms with a yellow gas, chlorine(Cl), which changes the physical state to a dickmuncher solid, but ultimately they reacted with each other chemically to form salt (NaCl). It does change the physical state, but it is more of a chemical reaction.


When sulfur is bright yellow solid is it chemical or physical change?

The transformation of sulfur from a bright yellow solid to a different colored solid would be considered a physical change because no new substances are formed. The change in color is due to the rearrangement of sulfur atoms, not a chemical reaction.

When paper turns yellow after a few weeks is it a chemical change or a physical?

Physical (I'm pretty sure). If there is no change in the formula/chemical makeup/etc. then the change is purely physical. If the newspaper ceased to be a newspaper and became something else, then it would be chemical.

This represents a chemical change, as the formation of a cloudy and yellow solution suggests the formation of a new substance with different properties from the original solutions.


Sulfur has a bright yellow color is this physical or cheimical property?

Its colour, its melting point, its boiling point, whether it is magnetic or not, whether it is an electrical conductor or not and its atomic mass are all physical properties.


Is salt forming a physical chance or chemical change?
