when will we found out our midterm marks?
I don't know, it's out of my hands. Soon.
Find your grade here.
After getting 'A' grades on 2 practice midterms, as well as reviewing mastering chemistry homework questions, my poor midterm mark did not at all reflect my practice. I have talked to several other students saying the same. Is there any chance of marks being curved or 'unfair' questions? (As I heard this was the case last fall)...
I'm sorry to hear your hard work did not translate into success in the midterm. We don't grade to a curve. Several people scored 100% and the distribution of grades was normal, suggesting a fair midterm. You will have plenty of further opportunities to demonstrate your ability.
I will be going through the midterm in class briefly this coming week, and will be able to address any questions of unfairness there.
For the midterm when dealing with molecular shapes, do we have to know the several other shapes that can be produced from the 5 basic shapes? Should we know bent, trigonal pyramidal, seesaw...etc or just linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral?
LEARN ALL THE THINGS!
Ahem, yes. You need to know all 5 shapes and the shapes derived from them. Fortunately, all are entirely descriptive, so you should be OK.
Do we need to know the angles of each shape for the midterm? Trigonal planar is 120 degrees, tetrahedral is 109.5 degrees, etc.
Yes. But all of them are easily worked out by inspection except for tetrahedral.
