Does a change of state always occur in a chemical change?
not always, like the change is in the display without change in composition then it is change of state, other then will be chemical change
Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
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.
What observations does not indicate that a chemical change has occurred a. change of state b. formation of a precipitate c. absorption of energy d. release of a gas?
Change of state does not necessarily indicate a chemical change. It could be a physical change, such as melting or freezing, where the substance remains the same chemically. On the other hand, the formation of a precipitate, absorption of energy, and release of a gas are all indicators that a chemical change has occurred.
Why are changes of state chemical changes?
They aren't; a change of state is a physical change
What happens to make a chemical reaction?
In A Chemical Reaction the following take place a) there is evolution of a gas b) change in colour c) change in state d) change in temperature
Is change of state a chemical change?
No, change of state is a physical change.
What is the difference between a chemical change and a change of state?
A chemical change involves a rearrangement of atoms to form new substances with different chemical properties, while a change of state is a physical change where a substance transitions between its solid, liquid, or gas state without changing its chemical composition.
Does a solution have a chemical change?
A solution does not have a chemical change, but it does have a physical change in state.
What makes a reaction to happen?
In A Chemical Reaction the following take place a) there is evolution of a gas b) change in colour c) change in state d) change in temperature
What is needed for a solid to sublime and what changes of state occur?
pressure and the change of state is chemical
Does a change of state always occur in a chemical change?

Is decaying a chemical or physical changes?
Better to state it a biochemical change if required can state it chemical change
Is the change of state a chemical or physical chenage?
A change of state is a physical change.
When bonds between atoms are broken or formed is the outcome A a physical change B an element increasing in size C a chemical change D a change of state?
C. a chemical change. When bonds between atoms are broken or formed, it involves a rearrangement of the atoms and results in the formation of new substances with different chemical properties. This is characteristic of a chemical change.

When Ethanol boils is that a chemical change or chemical property?
neither. it is a change of state.
