Numbers of the Periodic Table and Bohr-Rutherford

For how to figure out a) the number of protons, electrons and neutrons and b) how to draw a Bohr-Rutherford diagram see this great site!

(The pictures here are good, but the site is even better!)

Also, if you click on the pictures, you can view the whole picture (it is a bit cropped in the blog)

ziploc chemical equation

For the observing changes lab (ziplock lab) we combined baking soda and calcium chloride. Use the internet to complete the chemical equation:


calcium chloride + sodium bicarbonate → _____________________

or

CaCl2 + 2 NaHCO3 → _________________________
