Todays class we went over our homework, which was a small review of the Lab Safety Rules. Each student then received a green, yellow, and red card to let Mr. Doktor know if we were understanding what he was teaching throughout the lesson. (Green as in I fully understand, Yellow as in I need a few more examples, & Red as in I don't get it at all.)
First we learned what aqueous was (A solution dissolved in liquid) and some other few phase symbols. Ex: Al (s), H2O (l), AgNO3 (aq)
He then listed and explained the Diatomic Molecules: H2, N2, O2, F2, Cl2, Br2, I2
& Polyatomic (many) Molecules: P4, S8
Then Mr. D went through the colummns of the Periodic Table, & explained to us the noble gases, non-metals, and metals. We then took notes on Balancing & Word Equations & were taught an easier way to balance equations without drawing a chart.
An example would be balancing Double Replacement:
2AlCl3 + 3CO2 + 3H2O ---> Al2(CO3)3 + 6HCl
