To my understanding, if a product has low activation it is the kinetic product. Whereas if it had higher activation energy, it'd be the thermodynamic product and favored under thermodynamic control.

What do you call a tooth in water?

A molar solution.

I'm not sure how to mathematically prove it, but delta G is supposed to represent the maximum amount of work possible at constant pressure and temperature. Because G = H-TS = U+PV-TS.

If k is greater than 1, the products would be favored, while if k is less than 1, the reactants would be favored. That is because k is products/reactants.

To my understanding, the activated complex is referring to all possible intermediate molecules. The transition state is the intermediate with highest potential energy.

I'm not sure what you mean by energy coming from a reaction, but to my understanding when the volume is changing energy would be used in the expansion. So, less energy would be coming out from that.

Alexander Peter 1F

I believe you are correct, as to my understanding energy in this process is only transferred as work.

How I think this is done, is that you must first isolate [A], [B], and [C]. For example, starting with experiments 1 and 4, you see that the initial rate is the same, 2.0, and [A] and [B] remain the same between the experiments, however [C] changes and is independent of the initial rate. This means ...

To my understanding, half-life doesn't change because the rate it's getting rid of a substance is proportional to the amount. So, if there's more of a substance then it'll dissipate at a faster rate. Zero-order reaction, on the other hand, I think eliminates a given amount of a substance at interval...

Those are just two different ways of writing the same thing, to my understanding. You're still ending with 4s^1, one way is just summarized more at the beginning.

To my understanding, water is amphiprotic because it can donate a proton. It can also act like an acid or base making it amphoteric as well.

To my understanding, isoelectronic ions are ions with the same number of electrons. For example, F- and Na+ as they both have 10 electrons.

First off, assuming you had no problem creating the Lewis Structure, you'd see that Cl is the central atom with two double bonds to each O, and one lone e- pair. This shows that there are three e- densities around Cl, and they want to be as far apart as they can from one another. The shape that woul...

Coulombic Attraction is the attractive force between any two oppositely charged atoms. To determine which is the strongest, simply multiply the charges on the two atoms to see which is greater. For example, Ga^3+, O^2- would require multiplying 3 x 2 = 6. You can follow these steps with the other tw...

To my knowledge, having lone pairs does not change the sp3 hybridization as long as the intended shape is still tetrahedral. H2O, for example, is in a bent shape but has the electron pairs needed to attempt a tetrahedral shape, and it is sp3 hybridized.

To my understanding, KF is basic because F- is an exception, being the only halogen that can affect the pH of a solution. I believe this is because F- can form stronger bonds than say Br, even though they are in the same group. My knowledge ends here though, if anyone has a better explanation.

When you drew out the structure, you saw that there are 3 double-bonds between S and the O's. To my understanding, because these bonds are between atoms of different electronegativity, SO3 will act as a Lewis Acid. When exposed to an appropriate Lewis Base, one pi-electron pair should shift towards ...

To my understanding, when pressure increases then equilibrium shifts to the side with the least moles of gas. So, one mole of Cl2 versus two moles of Cl. Cl2 would be favored, I believe.

Alexander Peter 1F

When I attempted to draw this, I put two double bonds on a C, so it looked like C=C=N for that part of the structure. I was told a triple bond between the C and N would be preferred, removing the double bond between the C's. Is this a general rule that an atom doesn't want multiple double bonds to o...

To my understanding, for the first part of your question, the most stable state of an atom is indeed n=1 which is also called the ground state, when their energy level is lowest.
