What else can I help you with?
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.
Is freezing an example of an exothermic chemical change?
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
Is microwave physical or chemical change?
Using a microwave is a physical change because it involves the application of electromagnetic radiation to heat and cook food. Chemical changes would involve alterations to the molecular structure of the food, which typically does not occur solely due to microwave heating.
Is evaporated gasoline a chemical change?
No, it would be a physical change. During a chemical change, substance(s) are changed into different substances. An example of a chemical change would be the rusting of iron but a physical change would be freezing water; or in this case, evaporation.
Is a cooked hot dog physical or chemical change?
CHEMICAL:)
Is movement a chemical change?
No, That would be a physical change....A chemical change would be for like example: Water Evaporting, Water Boiling, Water Freezing...etc
Is breaking wood example of chemical change?
no, breaking wood is a physical change.If the wood was burned, that would be chemical change
What is a non example of a chemical equation?
I suppose that would be a summary of a change which is not chemical. Perhaps it would be something like ice --> water
How would you cause a chemical change to vinegar?
For example adding a base.
How can you tell the difference between a chemical change and physical change in matter?
You can tell a chemical and a physical change apart because a physical change is any change in size, shape, form, or state where identity of the matter stays the same.Example of a physical: If you cut a watermelon into chunks, the watermelon has changed size and shape.If you put one of the chunks into your mouth and bite it you have changed the size and shape again.Chemical change occurs when one type of matter changes with different properties chemical change goes around you everyday.Signs of a chemical change are the formation of a gas.yes because i wrote it!
What is the total of original and new substances that are the same after a chemical change?
It would be called a physical change, and would not be a chemical change at all. In order for a chemical change to occur, the original substances (reactants) must have different physical and chemical properties than the new substances (products).
Is milk sours a example of physical change?
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.
Is adding phenolphthalein to sodium hydroxide a chemical change?
No, adding phenolphthalein to sodium hydroxide is a physical change because it only involves mixing two substances together. A chemical change would involve a new substance being formed through a chemical reaction, which does not occur in this case.
Why the rusting of an iron pole is not physical change?
The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.
Is giving off light a physical or chemical change?
I would think it to be a Physical Change. Not chemical.
Is it true that food is an example of chemical change?
Not exactly but food, like any gas, liquid or solid, is made up of one or more chemicals. Plants growing is 'chemical change'. Food rotting is 'chemical change' Cooking food is 'chemical change'. Without 'chemical change' or chemical reactions, plants would not exist. Human beings would not exist. Anything we eat would not exist. Planet Earth would not exist!
