if during a change the chemical composition of the reactants change or any new products are formed then the reactant is said to undergo chemical change.
if the state, color, phase or any other physical properties of the reactant change without any change the chemical composition of the reactants or formation of any new substances then it is said to undergo physical change
What else can I help you with?
Is it a chemical or physical reaction?
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
What do physical changes do?
There are many different physical changes that can take place at any given time. To know what exactly these certain physical changes mean we would need to know what the changes are.
Is making a mixture a physical or chemical changehi?
yes it is because it is not changing the substance. EDIT: yes it is what? Is it chemical or physical? You probably mean it is a physical change.
Is the change of identity a physical or chemical property?
If you mean a change in chemical identity, that would be a chemical change.
Physical and chemical changes can be either exothermic or endothermic changes?
The two terms are probably used most often to describe chemical reactions - whether or not they absorb or require heat (endothermic) or create release heat (exothermic). However, since the terms simply mean "absorbing heat", and "giving off heat", they can be used to describe any such event, physical, chemical or nulear. Ray
What does reactants mean in science?
Reactants are the substances that participate in a chemical reaction and are consumed to produce products. They are the starting materials that undergo chemical changes during the reaction.
Is burning toast in the toaster physical or chemical?
Yes, it is. The process by which heat changes the molecules of the bread from white and soft to brown and crispy is a chemical change. A chemical change does NOT mean you have to add chemicals. It just means the chemicals (molecules) in the substance changed their chemistry. So slicing bread is a physical change, but toasting it is a chemical change.
Is slicing an apple is a chemical change or a physical change?
This is a physical change. You only change the shape and size of an apple by slicing it. Chemical changes would mean changing the molecular composition of the apple.
Is water dissolving in vinegar to give a solution a chemical or physical change?
chemical it never changes from liquid to gas or solid you know what i mean
What do you mean by an atom of a molecule?
the smallest particle of an element that maintains its chemical identity through all chemical and physical changes is called an atom
Why isn't the freezing point of a liquid a chemical property?
Because when something freezes, the atoms and molecules don't undergo a chemical change, they go through a physical change. By this, I mean that the individual atoms and molecules lose kinetic energy (energy that makes you move) in order to freeze. There is no chemical change here. Rather, the molecules and atoms are slowing down physically.
Is lighting a match physical change?
This is a little tricky. Striking a match is a physical act, but it does induce chemical changes. It depends on exactly what you mean by "lighting", ultimately. The end result is definitely a chemical change.
Is explosive a physical change?
By explosion, you mean combustion I presume. Because combustion is a type of reaction, explosions are chemical changes.
What do these physical changes mean?
There are many different physical changes that can take place at any given time. To know what exactly these certain physical changes mean we would need to know what the changes are.

What does it mean for someone to be dynamic?
Being dynamic means to undergo significant changes.
