During a chemical change, matter is rearranged to produce new forms of matter. This is a result of either the sharing or transfer of electrons between different atoms. Observable evidence of a chemical change can be, but is not limited to, the formation of bubbles, a change in color or temperature, and the presence of a smell.

Why are volcanoes a chemical change?
volcanoes are a chemical change because when it hits land it dicinagrates every thing, or it burns
Every time you experience anger your body experiences a dramatic chemical change called?
Fight or flight
How does chemical change improve the quality of life?
Chemical changes improve the quality of life in many ways. Medicines created from combining chemicals save lives every day, for example. Cooking is a series of chemical changes, for another example.
Chemical reactions can be detected by changes in?
Temperature change. The fourth class of reactions is much more difficult to detect than the previous three. This fourth class is really the basis of the other three. Every chemical reaction involves energy in some form, because all chemical reactions involve the breaking of old bonds, the forming of new bonds, or both. We know that every chemical bond contains energy, or it would not exist. This result means that every chemical reaction involves an energy change because the bonds are changed. Energy tied up in the bonds of atoms, molecules, ions, and the rest of the chemical system is called enthalpy. The absolute amount of this energy cannot be measured, but the change in enthalpy from the reactants to products can be measured. If the energy is lost (given off), the reaction is exothermic; if energy is gained, the reaction is endothermic
Every chemical compound?
A good note is to remember a chemical substance is a pure form of matter. A chemical element is pure chemical substance consisting of once type of atom distinguished by it's atomic number (quantity of protons within an atom's nucleus.)Where as a chemical compound is a pure chemical substance consisting of two or more chemical element.
What happens during every chemical reaction?
all chemical reactions.....they burn and dissolve
What is the chemical reaction that happens in every cell to break down sugar?

What event happens every day?
Change.
Does every chemical or physical change in matter include energy?
no
Is energy involved in every physical and chemical change?
It is true.
Is energy transfer involved in every physical and chemical change?
No
What is a chemical change that you observe in your every day life?

True or false every chemical or physical change in matter includes a change in energy?
Every chemical or physical change in matter includes a change in energy.
Is iron left outside to rust a chemical or physical change?
both, every chemical change causes a physical change, or the effects would not be apparent or even noticeable.
Why do elements react during a chemical change?
Because every atom aspires for the lowest possible energetical state, reachable under the given circumstances.
