What are 4 signs that a chemical reaction took place?
to tell if a chemical reaction has occurred look for these four things: 1) color change 2) the formation of gas bubbles 3) formation of a precipitate 4) temperature change
If a piece of metal bubbles was place in acid is that a chemical change?
No, it is not a chemical change. For example, if you put gold bubbles into any single acid, no chemical change will take place.
Is corrosion of aluminium metal a physical change or a chemical change?
It is a chemical change. Through corrosion, a chemical reaction has taken place.
What identifies a chemical change has taken place?
Signs that a chemical change has taken place include the formation of a gas, the formation of a precipitate, a change in temperature, and a change in color.
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)
What are not clues that a chemical reaction has taken place?
Phase changes are one example of a non chemical change. If the substance reacts the same way chemically, it has the same properties such as melting point, there has not been a chemical change.
What is an example of a color change that does not indicate a chemical reaction?
Many materials can change colour according to the temperature without there being any chemical reaction taking place.
