Is Pancakes Cooking A Chemical Change

1. What is a chemical change?
A chemical change is a change that results in the formation of new substances. This can be accomplished by either breaking down or combining existing substances. In order for a chemical change to occur, there must be a rearrangement of atoms. This rearrangement can result in changes to the physical and chemical properties of the substances involved.
2. What are some examples of chemical changes?
There are many everyday examples of chemical changes. Some common examples include:
-Cooking food
-Digesting food
-Rust on iron
-Tarnish on silver
-Burning wood
3. What are the characteristics of a chemical change?
There are several characteristics that are often used to identify a chemical change. These include:
-The formation of new substances
-A change in physical or chemical properties
-A rearrangement of atoms
4. How can you tell if a chemical change has occurred?
One way to tell if a chemical change has occurred is to look for changes in physical or chemical properties. For example, cooked food is usually different in appearance, texture, and taste from raw food. Another way to tell if a chemical change has occurred is to look for evidence of new substances. For example, when wood is burned, it forms ashes and smoke, which are new substances not found in the original piece of wood.
5. What is the difference between a physical and chemical change?
A physical change is a change that does not result in the formation of new substances. This means that the atoms present before the change are still present after the change. Some common examples of physical changes include:
-Cutting paper
-Tearing paper
-Melting ice cream
A chemical change is a change that results in the formation of new substances. This means that atoms are rearranged during the course of the reaction to form new substances with different physical and chemical properties. Some common examples of chemical changes include:
-Cooking food
-Digesting food
-Rust on iron
-Tarnish on silver
6. What are some examples of physical changes?
As mentioned above, some common examples of physical changes include:
-Cutting paper
-Tearing paper
