when atoms are combined or taken away and form a different molecule the substance you started with can no longer re-take its original form...example wood to ash from fire or heat, NOT an example is water to steam, that is a physical change and you can condense steam to re-make water.
What else can I help you with?
Are Fizzing or foaming evidence that a chemical change may have occurred?
yes it s an evidence that a chemical change has been occurred
Is a smelly sock a chemical or physical change?
A smelly sock is a chemical change because the release of odor is a result of chemical reactions occurring within the sock.
When you mix a pink powdered substance in water and mix it is that a chemical change?
Mixing is not itself a chemical change. There could be one occurring as a result, but nothing you described indicated any kind of chemical change.
What does evidence chemical change mean?
Evidence of a chemical change refers to observable signs that a chemical reaction has occurred. This can include color change, formation of gas or precipitate, temperature change, or production of light. These changes indicate that the substances involved in the reaction have undergone a chemical transformation at the molecular level.
Is balls of wax forming when melted wax is poured into ice water a chemical change?
No, the formation of balls of wax when melted wax is poured into ice water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of the substance, which is not occurring in this case.
When magnesium is burning in the presence of oxygen what are some evidence that a chemical change is occurring?
Some evidence that a chemical change is occurring when magnesium is burning in the presence of oxygen include the formation of a white powdery substance (magnesium oxide), the emission of light and heat, and the change in physical properties of the magnesium (e.g., color change or formation of ash).

A smelly sock is a chemical change because the release of odor is a result of chemical reactions occurring within the sock.
What does friction occurring at an interface always produce?
chemical change
What are the three signs that a chemical change is occurring?
solid,liquid,or gas
When a solution is heated and a gas is formed is that a chemical change?
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.
What are advantage of chemical change?
The biggest advantage of chemical change is life. All organisms are alive because of the sum total of all the chemical reactions occurring in their cells.
What changes gives NO evidence that a chemical reaction has taken place?
Changes such as a change in state (solid to liquid), change in color, change in odor, change in solubility, or change in temperature do not provide direct evidence that a chemical reaction has occurred. These changes can be indicative of a physical change rather than a chemical change. To confirm a chemical reaction, additional evidence such as the formation of new substances, evolution of gas, or consumption of reactants is necessary.
Is freeze-drying a physical property or a chemical property?
i would think physical, unless there is a chemical change occurring..... :)

Is vigorous bubbling when two substances are mixed an indication that a chemical change is occurring?
Yes
