All chemical reactions cause the change of color and the Change in temperature. Chemical reactions also have the characteristic of releasing gas.
A different state of matter is provided.
some chemical changes can be reversed but they are hard to reverse usually
All are examples of chemical changes
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
all the changes to a system cancel out APEX
All physical and chemical reactions , see text book from A to z .
wala
This is a chemical change because it has all the characteristics of one. The color changes, the texture changes, new stuff is created, and you can't separate by physical means. It is chemical.
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
some chemical changes can be reversed but they are hard to reverse usually
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Irreversible changes are changes which can not be turned back yo normal. These are chemical changes because the particles of the material have changed completely.
All are examples of chemical changes
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
all the changes to a system cancel out APEX
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
All chemical reactions are chemical changes.
all physical changes are alike in which all of them changing without changing in chemical makeup of the matter we have
