Should we memorize the strong and weak bases and acids for the final, or is this not of high importance?

longjump

Do compounds with carboxyl groups (-COOH) tend to turn into acids?

longjump

Are we required to know how to calculate the strength of an acid for the final?

Why is water left out of the Ka equation?

longjump

They are both the same, its just a different way of writing the compound.

longjump

Does anyone have a good quick synopsis or cheat sheet on naming compounds? I understand it for the most part, but I would like to make sure my notes are correct.

longjump

How do you know that something is an amphoteric compound?

longjump

DO we need to know the AXxEx equation that is mentioned in the textbook in regards to VESPR theory?

longjump

How will we be tested on bond lengths? Will it just be comparative or will we actually need to calculate bond sizes?

longjump

WIll understanding dipole moments be important for VSEPR theory?

longjump

Will we need to memorize the angles in VSEPR theory or just the shapes?

longjump

Is formal charge the best way to see if your lewis diagram is in the most likely arrangement, or is there another way to tell?

longjump

Which atoms MUST form an octet? Do these atoms always form one or does it depend on the molecule?

longjump

Does anyone know where to find past chem 14a midterm tests to use as a study reference?

longjump

Will periodicity be on the midterm?

longjump

What are all the exceptions for the building up principle?

longjump

If you are predicting which orbital an electron would be removed from to form a +1 ion, why would Mn get an electron removed from the 4s orbital and not the 3d orbital?

longjump

I know that it is hard to explain sketching online, but does anyone have any good ways to know which type of orbital to sketch?

longjump

Does anyone know if we will be quizzed on sketching the shapes of the orbitals on the test?

longjump

Can someone explain the answer to this question:

How many orbitals can have the following quantum numbers in an atom: (c) n=2

the answer is 4 but I'm not sure how to get there.

longjump

Can someone explain the meaning of psi^2? It was unclear what it meant in class to me.

longjump

WIll we need to know the different series' such as the Lyman and Balmer series' for the test?

longjump

Can someone explain uncertainty and indeterminacy in simpler terms? I'm just confused as to what it is a measurement of.

longjump

Does anyone have any good ways to memorize all the prefixes we need to know? Thanks

longjump

Can someone explain why light and photons and such are taught in chemistry instead of physics? It seems like beams of light don't have that much to do with chemicals because photons are not chemicals. A little clarification would be really nice, thanks.

longjump

If you wanted to find out if a wave was a UV wave, a visible light wave, or an X-ray wave, would you look at wavelength, wave frequency, or the energy of a wave to figure it out?

longjump

Does anyone have any good tips or tricks for solving balancing reaction questions? Writing the numbers out and calculating every guess works eventually but I feel like there is a faster way.

longjump

Will it be important to know all the different prefixes and their meanings such as G-giga-10^9 and n-nano-10^-9 for this course?

longjump

I'm not sure how to deal with the pentahydrate in the following example problem from section G.2: You are asked to prepare 250. mL of a solution that is approximately 0.0380 M CuSo4 (aq) from solid copper(II) sulfate pentahydrate, CuSO4x5H20. What mass of the solid do you need?
