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.
Flour and milk mixed a chemical or physical change and why?
Mixing flour and milk creates a physical change because no new substances are formed. The flour and milk retain their individual chemical properties, and the mixture can be easily separated by physical means such as straining.
Is juice freezing and forming popsicles a physical or chemical change?
The process of juice freezing and forming popsicles is a physical change. This is because the change in state from liquid to solid is a physical change that can be easily reversed by allowing the popsicle to thaw back into liquid form.
Rusting iron is it physical or chemical change?
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
Is mixing acid with base a chemical or physical change?
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
Is a given change a chemical or a physical change?
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
Is something that burns easily a physical or chemical change?
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
What is the difference between a chemical and a physcial change?
chemical change is easily reversible whilst physical is not reversible
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
Is boiling a chemical or physical change?
When water boils, it is a physical change.
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.
Is frozen water a chemical or physical property?
physical. because you can easily change it back to water form and/or a gas.
What type of change is an eyeshadow physical or chemical?
it is chemical because it can not be reversed
What is chemical and physical reactions?
A physical reaction is were the current substance can be changed in state and then changed back easily to it's previous state, a chemical reaction is the opposite, it is difficult to change it back to its previous state.
Flour and milk mixed a chemical or physical change and why?
Mixing flour and milk creates a physical change because no new substances are formed. The flour and milk retain their individual chemical properties, and the mixture can be easily separated by physical means such as straining.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
Is juice freezing and forming popsicles a physical or chemical change?
