Homework Help: chemistry

Posted by chemdummy on Friday, October 5, 2012 at 5:26pm.

When two solutions are mixed and a new color is observed, is this color change an indication that a chemical reaction has occurred? Explain.
It is not possible to directly observe chemical bonds breaking and forming during a reaction,
molecules and atoms are way too small. Instead we observe physical changes that may indicate
that a chemical reaction has occurred. Such changes can include the release/ absorption of energy
(heat and/or light), change in color or appearance, release of a gas, or the formation of a solid.Is this a right answer to this question? any wise comment will do
