63 Balancing Equations Activity
10/15/2014
..
Starter:
Arrange molecules into an equation: 2 Ag, 2 AgCl, 2 Cl,
Application:
Balancing Act Ws
Turn in when complete
Connection:
How is balancing equations like something you have done in math?
Exit: 2 H + CO3 → H2O +2CO2 Draw out this equation in your journal. Draw the atoms. Is this balanced or unbalanced? What does this have to do with the conversation of mass?

AGENDA8.5 F.
I will be able to recognize whether a chemical equation
containing coefficients is balanced or not and
how that relates to the law of
conservation of mass by reading, and
writing while completing notes and
activity.
