We
will be studying how different chemicals
combine. Often there is energy given off as
heat and light.
You remember the burning of the magnesium
ribbon? The reaction was
Mg + O2 -> MgO
But there are 2 oxygen atoms on one side of the
equation and only one on the other side!
The law of mass conservation says you can't
create or destroy matter, so we will need to
learn how to balance the equation.
Here
is the PowerPoint presentation on Chemical
Reactions that we saw in class on Tuesday

Don't forget to get your report
outline checked before March 12th
