IS percent ionization measured by dividing the change in concentration of initial concentration or is it measured by dividing the final by the initial????

For one of the problems in the homework, we are supposed to take the given stoichometic coefficients which are fractions. Numbers raised to a fraction are then represented as roots. However, what confuses me is that in the solution manual it says to combine the sum of all those fractions (1 on numer...

Or do dipole moments not really affect whether something is an acid or base?

If the k value for a system in equilibrium is a number, will it's reverse reaction be the same number? I assume yes because the rate at which products and reactants "go" into another should be the same?

They follow a similar formula and are both dependent on the ratio of the molecules in the reaction, what is the main difference between the two? Is the quotient simply when the rxn is not in equilibrium???

Some structures have their roman numerals written after the name, but others have it in the middle of the name. Is there any particular reason for this?

Is it because bonds are more tightly held together than electrons traveling around the orbital?

From what i understand they seem to be the same thing, but other sources tell me they are distinctly different things that can sometimes be the same depending on the molecular structure? Could anyone clarify as to whether they are the same or not? And if they are different does one influence the oth...

An easy way to remember the general trend is that electronegativity increases across the period tables (left to right) and decreases as you go down.

welcometochillis

Another way to think about it is if the structure ends up having an odd number of valence electrons. or a single unpaired electron (which ever makes more sense to you) because of this it is more unstable and therefore radical.

Is formal charge indicated by a particular number or just a notiation of + or - ??

Are there any exceptions to carbon being in the center of a structure?

Test 3 will cover chapters 1.5- the end of chapter 2. Uncertainty, schrodinger's eq, electron configuration, lewis structures will all be on the test.

Do you go through the energy levels first or do you go through orbitals first. for examples ig writing a notion that is 3s3d3p or do you write it 1s2s3s1d2d3d4d??

The v's in the equations are different. in the c/v equation "v" is actually a greek letter nu which represents frequency of things with no mass. In the h/mv equation V represents velocity of a particle with mass. That's why mass is usually somewhere in the equation, you are usually calcula...

For future reference how does one deal with the hard to deal with negatives while showing work? Someone suggested just ignoring them, but I don't think a TA will accept the negatives just disappearing without any reason.

Hi all, I was wondering if it is essential to remember all the general cutoffs for frequency categories for test two or if it will appear on our given sheet with the constants and period table.

Hi everyone, I came upon a question that asked to determine the inital numbers in a series from the given spectral light number (the one that indicated whether it is visible or not, and what color it should be). Anyone know how to confront a problem like this?

In addition to lavell's video module on the topic, this video provided a very clear understanding of the basics of LR problems. Hope this serves you all well! [youtube]https://www.youtube.com/watch?v=Mlu_v8rE1TY[/youtube]

Is there anything that will be provided during the test such as a periodic table or a master list of the formulas we've learned thus far?
