Yea, we are mostly focusing on s, p, and d.

205323697

What quantum number is independent from the others?

205323697

A photo with high energy would be able to eject electrons.

205323697

What are the steps to figure out the VSERP structure of a molecule?

205323697

Why are bronsted acids and bases important? what do they do

205323697

Isnt this why we draw a circle in Benzene?

205323697

How would we combine the two equations?

205323697

Would it take more energy to break a long or short bond length?

205323697

Would it be that the greater the difference in electronegativity, the more ionic a molecule can be?

205323697

Would most molecules have resonance structure?

205323697

Which SI units should we focus on memorizing?

205323697

What equation only uses nanometers to get an answer?

205323697

When we leave it in scientific notation, how many decimal places to we keep?

205323697

What will be asked in a problem in order to know that we have to use this constant?

205323697

What are some examples that we will have an -ate as the ending?

205323697

Just to clarify, when we do the spin state we have to first fill out all of the orbitals before putting two states together, right?

205323697

how do we use the atomic radius to calculate the bond length? what information would we need to know?

205323697

When we write the abbreviated form for an atom, what rules are good to remember when dealing with the d block?

205323697

what doe it actually mean to have a nodal plane?

205323697

Just to clarify, this only works with hydrogen or other atoms that have the same amount of electrons as Hydrogen, correct?

205323697

Would you be able to solve this if you were not given one of the variables to solve for either the delta p or delta x

205323697

I noticed that there are two different constants, why and when would we use both of them.

205323697

When would we prefer to use one of them instead of the other?

205323697

How do we know a molecule has multiple ligands

205323697

it could have multiple ligands.

205323697

How would we determine if a molecule is a cis/trans isomer based on its name?

205323697

How do we get from pH to pKa?

205323697

When do we know when one molecule is more acidic than another? if we are talking about the same atoms but the different amount of them, would it be safe to say that the one with more atoms tend to be more or less acidic?

205323697

How would we know the position of all the ligands?

205323697

By how much would an angle go up or down if we added a lone pair?

205323697

In what molecules would we usually see this behavior?

205323697

If a molecule is non-polar, would it still having these hydrogen bonding site if this is even possible?

205323697

If you do not draw the structure correctly, would you still be able to figure out if you have a negative and or positive pole?

205323697

When drawing the lewis structure of a molecule would we take into consideration of the atoms individual electronegativity? If so, how would that play into drawing the structure?

205323697

I notice that sometimes we will have a double bond instead of a single bond and in other cases we would keep all single bonds and draw out the other love pair electrons. I know that creating double bonds makes the molecule more stable, but how do we know when to do that?

205323697

Sometimes I saw an atom bonding with five other atoms, how does this happen and what other atoms have the same behavior where they have their octet of 10.

205323697

This may sound bad but sometimes you have to fake it till you make it in order to become it. So, by physically telling yourself out-loud that you know the content and that you're going to do good, you will actually do good.

205323697

Could we say that the bond lengths are the same when it comes to the changing of bond within the carbons? Or would they be changing every so often because they are rotating?

205323697

What is it shared space called when the two orbitals next to each other when there are two s orbitals, compared to having two p orbitals?

205323697

Does it matter if we have an ionic bond or covalent bond? Would we still calculate it the same way?

205323697

What would be the difference between a shell and an orbital?

205323697

What does it mean when we have two electrons that share the same quantum numbers? Does This even occur? Why or Why not?

205323697

What does it mean when we say that there are 5 d orbitals?

205323697

What can the threshold also be referred to if we are asked this on an exam?

205323697

How can we split this equation, if that is even possible?

205323697

Molecular mass deals with the sum of the amount of atoms in each element. if there are 8 Hydrogens then you want to multiply the mass of hydrogen by 8 since you have 8 Hydrogen atoms. You do this with all the other elements and at the end you add it all up to get your molecular mass.

205323697

Adding and subtracting have the same rule, after getting your answer you want to use the significant figure of the number that has the least set of numbers after the decimal. When you are multiplying or dividing you want to use the number with the least amount of significant figures.

205323697

In an example when you do have a fraction, you can always keep the numerator as the coefficient and whatever is the denominator, you can multiply both sides of the equation by that number so that both sides are balanced.

205323697

I have a little list that helps me with sig. figs.
1. All non-zero digits are significant
2. Zero's between non-zero numbers are significant
3. Leading zeros are not significant
4. Trailing zero's in a number showing a decimal point are significant

205323697

I usually write down the amount of atoms on both the reactants and the products and I balance the element that occurs the least and I continue to do this until the very end, if I am stuck on one element towards the end, I multiply both sides of the equation by a specific number and if you do that th...
