Polar molecules can bond with each other via dipole-dipole interactions, which are generally stronger than van der Waals forces.

Pollution has a lot to do where the most acidic rain is, the more polluted a city the more the acidity the rain will be.

How about the chemical workers… are they unionized?

oxygen is the lowest ionization level, therefore, it is the central atom.

Covalent bonds are the bonds between the atoms within the same water molecule. Hydrogen bonds are the bonds between two water molecules.

Why does hamburger yield lower energy than steak?
Because it's in the ground state.

Hydrogen bonding is the third type of van der Waals' forces. It is exactly the same as dipole-dipole interaction, it just gets a special name.

404817859

One of a set of Lewis structures that differ only in the distribution of electrons in covalent bonds and lone pairs.

What happened to the man who was stopped for having sodium chloride and a nine-volt in his car?
He was booked for a salt and battery

What is the name of 007's Eskimo cousin?
Polar Bond.

Sigma bonds form bonding orbitals between the nucleus of the bonding atoms, greater overlap and strong sigma bond. Pi is a covalent bond between orbitals perpendicular to the bond direction.

404817859

that is correct ^

9c) I know the answer is sodium but why don't we put the positive 1 charge :)

404817859

in drawing the Lewis structure where do you put the formal charges?

404817859

can someone further explain number 6c? I'm not sure how the wavelengths correspond with lower frequency

404817859

It is pretty cool to believe nothing is faster than the speed of light

what kind of fish is made out of two atoms?
2 Na

404817859

understand the concepts but equation wise it does not relate to Schrodingers equation

404817859

wow thank you now I know to make sure to take excellent notes and to keep them on hand

404817859

I tell bad chemistry jokes because all the good ones are Argon

404817859

your answer should be around 1.1x10^-34 m

404817859

That is correct, atoms are constantly in vibration even in there lowest kinetic energy

404817859

I think it will be very helpful to understand the concept, hence it would facilitate working out problems, but to have it memorized would be a stretch. To make sure I would ask the TA

404817859

sig figs will give more of an precise answer, either way should work :)

404817859

I believe a formula unit is the empirical formula incase that makes it easier to understand

404817859

Don't trust atoms, they make up everything.

404817859

Also, make sure to practice dilution problems, hence I noticed more people struggle on those...
