Physical Science

Remember, we will be finishing Chemistry on Wed. April 15 and we will begin Earth Science the next day.

The final quiz will include everything we have done since December (minus the whining).

Here are some balancing problems:

1.  H2 +  O2 --->  H2O            26.  N2   +   H2  --->   NH3

2.  S8 +  O2 --->  SO3            27.  N2   +   O2  --->   N2O

3.  HgO --->  Hg +  O2            28.  CO2   +   H2O  --->   C6H12O6   +   O2

4.  Zn +  HCl --->  ZnCl2 +  H2   29.  SiCl4   +   H2O  --->   H4SiO4   +   HCl
