What else can I help you with?
Is this statement true or false A chemical change is also called a chemical reaction.?
True. A chemical change refers to a process where substances transform into new substances through a chemical reaction, involving the breaking and forming of bonds. This transformation alters the chemical properties of the original substances.
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
Is breaking up concrete a physical change true or false?
True. Breaking up concrete is a physical change because it alters the size and shape of the material without changing its chemical composition. The concrete remains concrete, just in smaller pieces.
Is changing thesize and shape of pieces of wood a chemical change true or false?
false
Is combining hydrogen and oxygen to make it water is a physical change Is it true or false?
False. Combining hydrogen and oxygen to form water is a chemical change, not a physical change. During this process, the hydrogen and oxygen atoms chemically react to create new substances, resulting in the formation of water molecules. This transformation involves breaking and forming bonds, which is characteristic of chemical changes.

false
Is changing thesize and shape of pieces of wood a chemical change true or false?
false
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.
True or false .During a chemical change atoms are lost or gained to the new substance?
False
Is it true or false for A Change In State Is A Physical Change?
True. A change in state, such as from solid to liquid or gas, is a physical change because the substance's chemical composition remains the same and only its physical properties, like shape or state, change.
