Bronsted acid is a proton donor and a Bronsted base is a proton acceptor.
While a Lewis acid is an electron pair acceptor and a Lewis base is an electron pair donor.

Also, the conjugate acid of a base is the molecule formed when the base accepts the proton.

Salma Fawzi 4G

the conjugate base of an acid is the remaining molecule when the acid donates a proton (H+)

I also think that is a separate process, since hydrogen bonding is an intermolecular force.

you can use the reference on the class website to help you memorize

A complex is a species consisting of a central metal atom or an ion and a number of molecules or ions are attached by coordinate covalent bonds

a coordination compound is an electrically neural compound where at least one of the ions is present in the complex

the zero would be included in the sig fig in this example

Silver walks up to gold in a store and says, "Au, get out of here!"

Since lone pairs are still a part of the electron group, they will affect hybridization.

Salma Fawzi 4G

Sigma bonds have more overlap, while pi bonds have less overlap.

A proton and a neutron were walking down the street. The proton says, "Stop, I dropped an electron. Help me look for it." The neutron asks, "Are you sure?" The proton replies, "Yes, I'm positive."

A neutron walks into a shop and says, "I would like a coke."
The shopkeeper serves up the coke.
"How much will that be?" asks the neutron.
The shopkeeper replies, "For you? No charge."

Thank you!

An optimist sees the glass half full and a pessimist sees the glass half empty, but how does a chemist see it?...
A chemist sees it completely full: half with liquid and half with air!

most likely cumulative since its the final

Salma Fawzi 4G · Re: Final Yes its on December 8th at 11:30am to 2:30pm

Yes its on December 8th at 11:30am to 2:30pm

What time are the peer learning sessions in Covel tomorrow?

Salma Fawzi 4G

On the syllabus it mentions students need half the points to pass the class, so does that mean that the class is curved up?

Salma Fawzi 4G

I personally watch videos on Youtube whenever I don't understand a topic or need a quick refresher on the fundamentals (Khan Academy, Professor Dave Explains, and Bozeman Science are my favorites!). Aside from that, I find that solving many textbook problems with a study buddy and going back to re-...

Salma Fawzi 4G

Yes, the final exam is cumulative, and test 2 is only based on the information after the midterm.

Salma Fawzi 4G

Also, if you have a strong chemistry background then taking both Chem 14B and Chem 14BL may be a good choice since the material can overlap.

Salma Fawzi 4G

From what I've heard, taking both courses at the same time is doable, but Chem 14BL will take a lot of time and work. So make sure that you balance your workload based on the classes you are taking next quarter.

Salma Fawzi 4G

Also, on the syllabus there is information about the grading/points in the class that you can look at.

What did one charged atom say to the other.....
I got my ion you!

Salma Fawzi 4G

What sport was Avogadro best at?
Golf because he always got a mole-in-one!

Students ask: Why can you never trust atoms?
Someone's response: Because they make up everything

Salma Fawzi 4G

Oxygen, hydrogen, sulfur, sodium, and phosphorous walk into a store.... The cashier says "OH SNaP!"

Salma Fawzi 4G

Before it was mentioned that the class is not curved so I that means that there isn't a set about of grades to be given.

Salma Fawzi 4G

which topics will be covered on test 2?

Salma Fawzi 4G

also, is there an example that can clearly show the usage of hund's rule?

Salma Fawzi 4G

can someone explain hund's rule?

Salma Fawzi 4G

Does the ionic radius have the same periodic table trend as atomic radius?

Salma Fawzi 4G

And how can you find how many lone pairs are in a lewis structure?

Salma Fawzi 4G

What are lone pairs in a lewis structure?

Salma Fawzi 4G

Can someone give a few examples of resonance to clarify what it means?

Salma Fawzi 4G

@Haley thank you for the information!

Salma Fawzi 4G

Also, will this week's material be covered on the midterm as well?

Salma Fawzi 4G

Does anyone which topics will be covered on the midterm? Which topics will not be on this midterm?

Salma Fawzi 4G

What are the possible units for computing the wavelength?

Salma Fawzi 4G

What is the exact value for the speed of light and how was this number calculated?

Salma Fawzi 4G

What is the connection between frequency and velocity in wavelengths?

Salma Fawzi 4G

What is the relationship of wavelength and the intensity?

Salma Fawzi 4G

How is energy indirectly proportional to wavelength using the equation ?

Salma Fawzi 4G

how should we first approach limiting reactant problems? Also, how can you tell which molecule is or isn't the limiting reactant?

Salma Fawzi 4G

it's better to round your final answer so your calculation can be correct. If you round each step of your problem, then your sig figs might be incorrect towards the end.

Salma Fawzi 4G

The empirical formula should not have fractions or decimals. You can manipulate the numbers by multiply by a number that will result in whole numbers in the formula only.

Salma Fawzi 4G

Avogadro's number is 6.022*10^23 and it can be used to convert moles to atoms

Salma Fawzi 4G

keep your calculations precise and then round your final answer so you have an accurate calculation
