What else can I help you with?
How can a chemical change help you tell the difference between a compound and an element?
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
A chemical property is a change in what?
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.
What does a word equation or a chemical reaction tell you?
I think that a chemical equation tells a chemist that substances you start with and substances you end with
How can you tell a chemicall reaction has happened?
You can tell a chemical reaction has occurred if there is a change in color, formation of a gas, production of heat or light, formation of a precipitate, or a change in properties of the substances involved. These are observable signs that a chemical change has taken place.
When ice melts why can you tell there is not a chemical change?
Melting is not a chemical change because the chemical formula of water remain unchanged.

Is it possible to tell whether a chemical change has occurred by watching atoms form new substances?
if the atoms form substances that are chemically different from the reactants, then a "chemical" change has occurred.
How can you tell by look at a chemical equation which substances are products?
In a chemical equation, the substances on the right side of the arrow are the products. These are the new substances that form as a result of the chemical reaction taking place.
How can you tell chemical change?
The consequence of a chemical change is the modification of the molecular nature.
A chemical property is a change in what?
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.
How you tell if matter has undergone a chemical change or a physical change?
If a chemical change has occurred, the chemical composition has changed and new products will have formed, different from the reactants. If a physical change has occurred, the chemical composition does not change and no new products will have formed.
What does a word equation or a chemical reaction tell you?
I think that a chemical equation tells a chemist that substances you start with and substances you end with
How do we know a chemical change has happened?
You can tell if something is a chemical changes or a physical change. Examples: Question 1) Ice melting. Answer 1) Physical change because nothing has changed just the shape of the ice. Reversing ice is easy. Question 2) Wick on a candle changes colour from white to black. Answer 2) Chemical change because it changes from clack to white and will be hard to reverse. So if it is a chemical change taking place it hard to convert back or reverse. You can also tell by the change of colour.
How can you tell there is a chemical reaction when iron rusts?
Because it is not a physical change it is a chemical change.
How can you tell a chemicall reaction has happened?
You can tell a chemical reaction has occurred if there is a change in color, formation of a gas, production of heat or light, formation of a precipitate, or a change in properties of the substances involved. These are observable signs that a chemical change has taken place.
Chemical properties tell you how something?
Chemical properties describe how a substance behaves in a chemical reaction, such as its reactivity, ability to react with other substances, and changes in composition. These properties are determined by the substance's chemical composition and structure.
When ice melts why can you tell there is not a chemical change?
Melting is not a chemical change because the chemical formula of water remain unchanged.
