I definitely feel that the textbook has a lot of information that the finals and tests won't cover.

Practice problems in my opinion are the best to review.

Med school seems daunting right now but your advice is helping.

Sit, breathe, and tell yourself that you will do well! Even if you don't, I'm sure you tried your best.

Do every homework problem introduced, and the practice problems Dr. Lavelle posts are really good too.

The textbook does have a lot of extra information that may not be covered, but it's a good comprehensive guide and the practice problems it introduces are good to do before midterms and finals.

Your final answer needs to have correct sig figs for full points I believe, and I think there is partial credit for longer problems.

It is used for questions that involve wavelengths of light that are emitted when electrons change energy levels.

Often acids will contain either H or OH

When energy is absorbed by water, does it release heat?

How do you tell the difference between when it is an anode vs when it is cathode?

Wouldn't the difference from 720 to 700 make a significant enough difference?

Resonance: Movement of electrons within molecules.
Delocalization: Electrons ability to de localize, or spread out into more space.

Valence electrons for the non metals can basically be counted just by going across the periodic table, for example; Li:1, Be:2, B:3, C:4, N:5, O:6, F:7, and Ne:8. And that pattern follows down the columns. For non metals, count across the periodic table. Each corresponding element should have the sa...

It's just the energy that is released when oppositely charged gas ions form a solid

Electronegativity is the ability of an atom to attract electrons to itself when it is part of a compound. I think electronegativity decreases down a group and increases across a period. It is essentially how well an atom within a compound can attract electrons. Electronegativity decreases down group...

Always round at the end.

This is a pretty broad question. There are many different types of energy. Thermal, electrical, potential, kinetic, mechanical are all types of energy. They each have their different attributes, however, in terms of defining them as "energy." In other words, there are different factors tha...

The sun does not employ typical combustion reactions. Instead of oxygen, it uses hydrogen molecules to convert them into helium. The fusion reaction produces heat and light.

I recommend buying a 3D molecule model kit (there's also a free program that Professor Lavelle provides for us) It makes things a lot easier when learning shapes and arrangements.

bloodorangefield

Geometry means how both bond electrons and lone pairs are arranged, whereas shape only refers to the arrangement of the bond electrons.
