What's the difference between amphiprotic and amphoteric?

Marykate Abad 3L

Know both. If you know the concept, you'll know the formula.

Marykate Abad 3L

We do not have to know that. It was just background information and stuff we will learn in 14B.

Marykate Abad 3L

In the syllabus it says we should be able to "explain why rain can be acidic and discuss possible options to reduce 'acid rain'."

The roman numeral represents the oxidation state of the metal.

Marykate Abad 3L

The oxidation state of the metal is the roman numeral.

Marykate Abad 3L

It is cumulative. Make sure you understand the topics in the outlines.

Marykate Abad 3L

The final could ask to name compounds either way. It’s best to know how to do both.

Marykate Abad 3L

We are expected to know how to name ligands.

Marykate Abad 3L

You don’t need to write the subscript 1.

Marykate Abad 3L

One or two lone pairs can form a bent molecule

Marykate Abad 3L

Yes. A triple bond has 1 sigma and 2 pi bonds.

Marykate Abad 3L

Bond order is a measurement of the number of electrons involved in bonds between two atoms in a molecule.

Marykate Abad 3L

A triple bond contains 1 sigma and 2 pi bonds. The order does not matter.

Marykate Abad 3L

We do not need to know hybridization for Test 2.

Marykate Abad 3L

Yes, but the name we use for our homework and exams will probably be seesaw.

Marykate Abad 3L

Why do lone pairs repel bonded electrons more than other bonded electrons do?

Marykate Abad 3L

Yes. There are charts online to help memorize them.

Marykate Abad 3L

Test 2 covers everything after the midterm, but not hybridization.

Marykate Abad 3L

An ionic bond is between a metal and nonmetal while a covalent bond is between two nonmetals.

Marykate Abad 3L

Electronegativity increases from left to right and up the periodic table.

Marykate Abad 3L

We will not be given an electronegativity chart. We should know the general trends for electronegativity.

Marykate Abad 3L

C-F has more ionic character than C-Br because C is more electronegative than Br.

Marykate Abad 3L

You can draw one structure unless the questions states to draw the resonance structures.

Marykate Abad 3L

Isoelectronic means having the same number of electrons.

Marykate Abad 3L

We will only be given the electronegativity table. We are expected to know the trends of the table.

Marykate Abad 3L

The longer the bond, the weaker the bond.

Marykate Abad 3L

Ionic bonds are between a metal and nonmetal. Covalent bonds are between two nonmetals.

Marykate Abad 3L

The atom with the least electronegativity is the middle atom.

Marykate Abad 3L

Cations are smaller because they have less electrons which causes less repulsion making the protons pull closer to the nucleus.

Marykate Abad 3L

I believe just focus on those two

Marykate Abad 3L

Their electrons fill and half-fill two subshells, with some electrons in the higher energy level shells

Marykate Abad 3L

f contains 7

Marykate Abad 3L

Electrons are filled parallel in each orbital first and then become paired after each orbital has an electron

Marykate Abad 3L

You can use the noble gas before it to substitute writing out the entire thing.

Marykate Abad 3L

1 J = 1 (kg*m^2)/s^2

Marykate Abad 3L

All of them increase

Marykate Abad 3L

That number is R, Rydberg's constant!

Marykate Abad 3L

I'm a visual learner so youtube always helps me. Depending on your learning style, try and find what works best for you! It goes a long way

Marykate Abad 3L

Vanadium

Marykate Abad 3L

Ionization energy increases from from left to right because elements are more likely to give up their electrons on the right side of the period table.

Marykate Abad 3L

De Broglie's equation can be used to solve for an object's wavelength given a mass.

Marykate Abad 3L

I feel that amplitude is focused more in physics and not in chemistry so I wouldn't worry too much about it.

Marykate Abad 3L

Depending on the problem given and values given, you can rearrange the equation to plug in what you are given/looking for.

Marykate Abad 3L

Your answer should be the least amount of sig figs given in the problem.

Marykate Abad 3L

All chemical reactions should be able to be balanced. If fractions are involved, multiple by the denominator to get rid of it.

Marykate Abad 3L

Combustion also means burning. In every combustion reaction, the reactant reacts with oxygen and produces water and carbon dioxide.

Marykate Abad 3L

I bought a scientific calculator for this class because the syllabus says non-programable calculator is required

Marykate Abad 3L

You would round to the least amount of sig figs given in the problem. For atomic mass, 3 decimal place is fine.
