In a chemical reaction, no atoms are lost. It is basically a mixture of two substances.
Below is an example. (Though I'm just using random letters -- the symbols don't actually make a substance)
AJK + JD = AJ2KD
In a chemical change, a completely new substance with new properties is created.
Here is another example. (Though, again, I'm just using random letters -- the symbols don't actually make up a substance)
AJK + JD = AJKD
What else can I help you with?
Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
A chemical change is also called a chemical reaction?
This is true.
Does the number of atoms entering the reaction stay the same as the number put out by the reaction?
In a balanced chemical reaction, the number of atoms entering the reaction as reactants is equal to the number of atoms leaving the reaction as products. This is because of the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
When a chemical reaction and it and reverse are occurring at the same time and at the same rate the reaction has achieved?
equilibrium
Is a chemical change the same as a chemical reaction?
They are just two different terms that mean the same thing.
Is a chemical change a chemical reaction?
Yes. The two terms mean the same thing. They are synonyms.
Can you call a chemical reaction a chemical change?
They are just two different terms that mean the same thing.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What is the word for a chemical change in a substance?
A chemical change is the same as a chemical reaction.
Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
Chemical change same as chemical reaction?
no because a chemical change is any process in which 1 or more substance is changed into 1 or more substances whereas a chemical reaction is a process that leads to a transformation of one set of chemical substances to another
A chemical change is also called a chemical reaction?
This is true.
How many atoms are in a chemical change?
the same as before the reaction
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
Freezing involves a chemical reaction?
No, freezing involves phase change, which is a physical change. There is no chemical reaction, as the basic chemistry is unchanged it is still the same material in a different physical state.
Is an indicator's reaction in acids and bases a chemical change?
No, an indicator's reaction in acids and bases is a physical change. Indicators change color based on the pH of the solution they are in, but the chemical composition of the indicator remains the same.
