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.

∙ 13y agochemical change can cause good effects to us because chemical change can produce new materials or objects that we can use by mixing chemicals like if you mix sodium and chlorine you can get sodium chloride or what we know as salt.

Does a chemical change effect mass?
Mass is a constant Quantity according to Newtonian Physics.
Is producing heat chemical or physical change?
Producing heat is caused by a chemical process which results in physical changes. The cause is chemical. The effect is physical. :) :D
What effect does aging have on a nickel?
tarnishing (a chemical change)Exposure to oxygen in the air or water causes a chemical change to occur on the surface of the nickel. This results in the nickel turning a black color.
Is taking a photograph a permanent chemical change?
Modern photography uses chemicals to generate the photographic effect of a camera.
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.
What are the good effects of physical change and chemical change?

How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
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.
What type of change will effect the state of matter but not its chemical makeup?

BAD EFFECTS:Acid RainBurning of Wood
Does a chemical change effect mass?
Mass is a constant Quantity according to Newtonian Physics.
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.)
