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 changing thesize and shape of pieces of wood a chemical change true or false?
false
When a chemical change occur the product have a greater mass than the reactants true or false?
yes
Is this statement true Ice being broken into small bits is an example of a chemically change?
No it is not, as the ice will still retain its chemical properties. This is an example of a physical change. Remember that the indicators of a chemical change are a change in colour, a change in odour, a change in temperature, the formation of a precipitate, or a gas being given off.
What is the breaking of a glass window is a physical change is true or false?
True.

Is this true or false in a chemical change other forms of energy cannot be changed to chemical energy?
False
When substances are mixed it can result in physical or a chemical change true or false?
true
Is it true are false that a physical change of a substance changes its chemical makeup?
true
Dissolved salt in ocean water is an example of a chemical change true or false?
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.
Is this true or false in a chemiccal change other forms of energy cannot be changed to chemical energy?
False. In a chemical change, other forms of energy, such as heat or light, can be changed into chemical energy. This transformation can occur during reactions where energy is either absorbed or released as chemical bonds are broken or formed.
