Practice balancing chemical equations using colored atoms - from simple to complex equations. Check folders for materials. Test your skills with Quiz #2 on balancing equations. Evaluate and correct equations like 2Ca + Br2 = CaBr3.
E N D
Warm up • Use the colored atoms you made the other day to see if this is a balanced equation • MnO= Mn+ O2
Warm up answers • 2 Mn2O= 4 Mn+ 1O2
Correctly multiplying • H2O = 2 Hydrogens, 1 Oxygen • 2 H2O = 4 Hydrogens, 2 Oxygens • (OH)2 = 2 Oxygens, 2 Hydrogens
Todays activities • Folder check – all warm ups, notes, cool downs and worksheets from 04-11-14 through 04-30-14 • Quiz #2 on balancing chemical equations
Cool down • Is this a balanced chemical equation? If not, rewrite it so it is balanced • 2Ca + Br2= CaBr3
