Mainly caused by chemicals like SO4^2- and NO3- coming from burning fossil fuels, such as coal.

Magnesium ligands are in chlorophyll and critical for electron transport chain there.

Technically De Brogile equation can be used on anything with rest mass; however, the equation is not so helpful on macro objects since their wave property is not obvious.

Melting and boiling point depend on intermolecular forces. NH3 is polar with its two lone-pair electrons when CH4 is not. As a result, intermolecular forces between NH3 molecules are stronger.

The angle between two ligands need to be around 90˚.

Nitrogen is more electro negative since it has more protons than carbon does.

305127455

We just add an H+, and for determining the conjugate base, just subtract an H+.

305127455

Lewis acid has space for insertion of lone-pair electrons, like AlCl3 in which the Al has 6 bonded electrons and, thus, space for 2 more electrons. Lewis base has lone-pair electrons on the central atom. Brønsted acid donates H+ while Brønsted base accept H+.

Longer bonds are weaker, and, thus, easy to break. This means it is easier for H+ to be released, so acids with longer bonds on hydrogen are typically more acidic.

Water is "aqua", which starts with "A."

Taking H2O as another product of the reaction and filling the reactants should work.

305127455

Conjugate acids and bases exist in pairs, typically one on the left of the equation, and the other on the right of the equation. For example, in the equation H2SO4 + H2O → HSO4- + H3O+, H2SO4 donates an H+ and becomes HSO4-. In this case, We say H2SO4, relative to HSO4-, is conjugate acid since it d...

If the complex has a total negative charge, add -ate at the end of the metal name. If the complex has a negative charge while the metal name comes from Latin, use the Latin stem.

For example:
Fe: -ferrate

305127455

We can know it by looking at the valence shell of the central metal and the total charge of ligands. However, there should be more information most of the time.

305127455

Writing in OH2 instead of H2O illustrates that it is the oxygen actually binding to the metal, so we should write OH2.

305127455

In the scope of 14A, yes I think.

There are 8 common strong bases worth committing to memory. It consists of Alkali and Alkaline Earth metals paired with Hydroxide Ions. LiOH - lithium hydroxide NaOH - sodium hydroxide KOH - potassium hydroxide RbOH - rubidium hydroxide CsOH - cesium hydroxide Ca(OH)2 - calcium hydroxide Sr(OH)2 - ...

305127455

I don't think we need to know how to derive it since pH is just an invented representation of proton concentration. For acid it's (-log[H+]), for base it's 14 - (-log[OH-])

305127455

Looking at the formula and calculating bonds and valence electrons should do.

305127455

Long pairs does count, and memorizing this and "formula" of hybridization should be enough to solve most of the related problems.

305127455

I don' t think we need to remember that. Perhaps the question will give us a diagram and let us tell.

I think we only need to remember those basic ones, such as 109.5˚, and how change in structure (like adding lone-pair electrons) can affect them.

305127455

I guess it's better to memorize that since it may be included in questions.

305127455

I thinks the question will instruct you if it does want to test your understanding of resonance structure. Otherwise, just leave it.

305127455

It will require tons of calculation and some mathematic models to determine the exact angles. Also, electrons are not "solid" there since they are actually cloud. This perhaps makes stuff even more difficult.

Even though I guess becoming a Spiderman also requires a strong body that can endure such great acceleration.

Thank you Dr.Lavelle for this quarter's great lectures and other studying experiences such as The Online Community. Also, your music does make me feel more relaxed, which is important for high study efficiency.

The Psi here means the probability to find an electron in a certain space while the Psi in the photo electric effect means threshold energy.

305127455

So the reason why dipole force is always attractive is because molecules are always tend to be stable, and attracting each other to stay together is the way to do this?

305127455

So those won't be involved in the final either?
