What is the basic difference between physical change and chemical change?
Well a physical change is when you break something and you still have it like ripping a piece of paper. You still have the paper!! Then you have your chemical change .Which is when you do something to make it to the point were you cant keep it.(EX) Burning a piece of paper in the fire is a chemical change:) Because you cant get it back:)
What is an effect of a chemical change?
A chemical change is when substances become new substances that cant go back to its physical properties (the ability to participate in chemical reactions). Chemical changes usually absorb or let off heat. Often, a second chemical change is needed to reverse an initial chemical change. A chemical change is when substances become new substances that have different chemical properties (the ability to participate in chemical reactions). Chemical changes usually absorb or let off heat. Often, a second chemical change is needed to reverse an initial chemical change.
What is a chemical reaction is on the 5th grade level?
A chemical reaction is when two or more substances mix together and change to form new substances. It's like mixing ingredients to bake a cake – you can't go back to the original ingredients once the cake is baked.

Sodium carbonate is a compound. Until you react it with something, it cant have or be a chemical change.
Why can't some substances not go through chemical changes easily?
Some substances have stable chemical structures, making it difficult for them to undergo chemical changes. This can be due to strong bonds holding the atoms together or a lack of reactive sites for other substances to interact with. Additionally, factors such as temperature, pressure, and presence of catalysts can also influence the ease of chemical changes in a substance.
Is a riping fruit an example of chemical or physical change?
Chemical, because you cant undo it
Is burning a chemical physical or chemical change'?
Anything that is burning is a chemical change.It is also a physical change. So both!See the Related Questions for more information.Chemical Changeyes because when you burn something you cant have back the way it was before you burnt it so it is chemical changeIt is a physical change i believeBurning is a chemical change.Burning is a chemical change because it converts two or more chemical substances (usually oxygen and an organic compound) into another set of chemicals (usually water and carbon dioxide)
