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.

Why is a glowstick a chemical change?
A glowstick undergoes a chemical change when the chemicals inside mix, leading to a reaction that produces light. This change cannot be reversed, as the reaction permanently alters the composition of the chemicals inside the glowstick to create the glowing effect.
Is taking a photograph a permanent chemical change?
No, taking a photograph is not a permanent chemical change. It is a physical change where light is used to create an image on a photosensitive surface, but the chemical composition of the materials involved typically remains the same after the process is completed.
Does a chemical change effect mass?
Yes, a chemical change does affect mass. This is because during a chemical reaction, new bonds are formed or broken, leading to a rearrangement of atoms. This can result in either an increase or decrease in mass.
Is hammering gold until it becomes flat a physical change or chemical change?
Pounding a gold coin into a different shape would probably not effect a chemical change. If, however, the pounding produced enough heat to meal the coin, some chemical change could take place.
A change in matter that produces new substances is called?

How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
Is toasting bread a chemical change or a physical change?
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
Does temperature have an effect on the rate at a physical or chemical change?
Yes, temperature have generally an important effect.
Does temperature have an effect on chemical reaction?
Yes, because the temperature can change the state of the elements being chemical;y tested so yes it does have and effect
What are two effects caused by a chemical change?
Two effects that are caused by a chemical change are changes from one substance into another. Another effect that can be caused by a chemical change is a change in the temperature of the surrounding system and substance, or a change in color of the substance.

by exessive use of juices and cold drinks.
Does a nuclear change result from a chemical reaction?
Nope. (Well, the chemical reaction of the high explosives in an A- or H-bomb warhead result in high pressure that then results in a nuclear change (BOOM), but that's a side-effect, not a direct result of the chemical change.)
Is dissolving a drink mix in water a physical change or a chemical change?
i think physical and chemical because for physical u r mixing it with the water. And for chemical I think it is because mixing drink mix with water is goes the effect the outcome chemical produced with both so it can also become a chemical change.....................
What is the effect on a chemical change on the mass of matter?
chemical changes disturbs the structure of the substance and hence reduce the mass....thx...with best regards..
