Changing water to ice is an example of a chemical change true or false?

I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.

∙ 12y agoNo. If you melt anything it's a physical form because it just changed into liquid not into a butterfly or something like that

Is changing the size and shape of pieces of wood a chemical change true or false?
False. Changing the size and shape of pieces of wood is a physical change because the wood's composition does not change.
Is a tree that is cut into boards at a sawmill a chemical change?
Sawing a board in half is not an example of chemical change. It is an example of a physical change. Physical changes on a substance do not change the substance. When you saw a board in half, the two halves of the boards are still boards- they're not anything else.
How Chemical equations are balanced by changing the subscripts of the molecule true or false?
False. They are balanced by changing the coefficients.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
The chemical properties of the aluminum change as you cut the can?

A chemical reaction causes a chemical change true or false?
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
Is a physical change what happens when chemical bonds break and new bonds form?
NO, that's an example of a CHEMICAL change

Is this true or false in a chemical change other forms of energy cannot be changed to chemical energy?
False
True or False When a chemical reaction occurs the physical and chemical properties of the reactants are the same as the properties of the products.?
unnecessary will change physically depending on what type of reaction, sometime chemically change . For example physically change are ice to water (solid to liquid) Chemically change are HCl + NaOH = NaCl + H2O ( the content changed )
True or false food is an example of chemical energy?
It is true.
