Data Analysis: Write the balanced equations for any (10) reaction that you see any cloudiness or color change. For each of the reactions that happened make sure to identify the solubility of each product. Remember to balance at the end!

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.

How do you know when a chemical reaction has occurred
