Today we wrote a quick quiz on naming and writing formulas for ionic and covalent compounds. Next we took notes on how to determine the number of atoms in a chemical formula for chemical reactions. We did THIS worksheet (9 questions minimum) and checked our work with the key.

Biology 12
Today we worked on our biochemistry game and got the Module Questions for the digestive system. A and B in the module are due Tuesday.

This week we wrote our Quest on DNA and protein synthesis. Next we started the body systems unit on Digestive System. The notes are HERE and power point HERE.
Science 10
This week we practiced mixed ionic and covalent naming with a quiz on Friday on this topic. Remember that if you have a compound with two non-metals, DON"T look at the charges, just use the prefixes.
Call this: N2O5 dinitrogen pentoxide due to the number of each atom in the formula:
1) due this week: Text book reading Page 123-126. Due the purple questions on page 124 and 126 for marks.
2) Turn in lab Physical and Chemical Changes (handout) with the questions answered and a Conclusion
3) Complete lab: Law of Conservation of Mass. Page 136-137 in text. Complete all questions at the end of the lab. This includes a graph on graph paper.
We also took notes on the law of conservation of mass. Notes are found HERE and power point HERE. We also practiced word equations and skeleton equations. This is found HERE.
