DPatel_2L

If Q<K it would favor the products and vice versa.

DPatel_2L

G naught is under standard conditions.

DPatel_2L

When the reaction is reversable.

DPatel_2L

Use the one that matches the units.

DPatel_2L

Cp is heat capacity at a constant pressure while Cv is heat capacity at constant volume.

DPatel_2L

The log equation assumes 25 degrees.

DPatel_2L

Use Kelvin.

DPatel_2L

If the system does work then the value is negative.

DPatel_2L

It is calculated in the same way, but it is just not at equilibrium.

DPatel_2L

If the system is doing work then the sign is negative, but if work is being done then it is positive.

DPatel_2L

It can either stand for Kelvin or the constant.

DPatel_2L

Use the value with the same units in the problem.

DPatel_2L

It is favorable when delta G is negative meaning it is spontaneous.

DPatel_2L

G° is under standard conditions.

DPatel_2L

the reaction will be spontaneous when delta G is negative.

DPatel_2L

It is possible, but I do not think it is in the scope of this class.

DPatel_2L

A change in temp or an addition of a catalyst will change k.

DPatel_2L

It will only change due to a temperature change

DPatel_2L

It means that there is no heat transfer.

DPatel_2L

Thank you!

DPatel_2L

They are formed and used up in the reaction, so should not be included.

DPatel_2L

Thermodynamics

DPatel_2L

Yes it is possible, but likely would not be very big.

DPatel_2L

Kinetics refers to the rate while thermodynamics deals with stability.

DPatel_2L

The best ones have the highest reduction potential

DPatel_2L

Yes make sure to include states of matter

DPatel_2L

the problem will typically state which one it is.

DPatel_2L

N is the moles of electrons transfered

DPatel_2L

E naught is under standard conditions

DPatel_2L

Yes it is the same standard conditions for both

DPatel_2L

An isolated system is one in which there is no interaction with the outside environment.

DPatel_2L

A negative delta H denotes a release of heat so it would be exothermic and when delta H is positive it means it is endothermic.

DPatel_2L

Enthalpy is the amount of heat in the system, while entropy is the disorder of the system.

DPatel_2L

It can help determine which variables are constant within the equation.

DPatel_2L

because it depends on the path that it takes.

DPatel_2L

Closed systems do not allow for an exchange of matter.

DPatel_2L

Yes, you can rearrange the equations.

DPatel_2L

It means that no energy is lost in the system.

DPatel_2L

The change in temperature because as you increase by one kelvin celsius also increases by one.

DPatel_2L

It is because there is more energy involved in changing a gas to liquid and then cooling it.

DPatel_2L

When bonds are broken energy is required, and then they are made energy is released.

DPatel_2L

It says enthalpies are state functions and can be added,

DPatel_2L

I do not believe that we need to memorize any in particular

DPatel_2L

We can assume it is insignificant when x is less than 10^-4.

DPatel_2L

The gas does not react so the partial pressures do change.

DPatel_2L

you would do 10^-(pKa) to do the negative log.

DPatel_2L

Use the one that matches the units

DPatel_2L

You chose the one that matches the units of your other values

DPatel_2L

The value is only based on the initial and final value

DPatel_2L

Endothermic requires the addition of heat energy, while exothermic releases heat energy

DPatel_2L

The IMFs are stronger so it will flow slower.

DPatel_2L

Both melting and boiling points increase when IMFs are stronger.

DPatel_2L

the anion has to have more than one H

DPatel_2L

When it is able to donate multiple protons!

DPatel_2L

They are the same thing!

DPatel_2L

pH=-log[H+]

DPatel_2L

Both are the same thing

DPatel_2L

Yes it is.

DPatel_2L

Water can be either.

DPatel_2L

Both work but I think OH2 is preferred.

DPatel_2L

Exclude the prefix when you are arranging it.

DPatel_2L

thank you!

DPatel_2L

Cl because it is furthest to the right nearest to fluorine

DPatel_2L

Both increase across a period and decrease down a group.

DPatel_2L

Memorizing is most likely the easiest way of keeping track of them.

DPatel_2L

I don't think the order matters, as long as you state one sigma and two pi bonds

DPatel_2L

Yes, they are always present.

DPatel_2L

Yes that would make the most sense.

DPatel_2L

A single bond is a sigma bond while a double is one sigma and one pi

DPatel_2L

CO2 because the oxygen is more electronegative

DPatel_2L

It should say s02 instead.

DPatel_2L

A coordinate covalent bond is when one atom shares both of the elections needed

DPatel_2L

The lowest formal change would be the mots accurate so I would think so.

DPatel_2L

I don't believe we need to.

DPatel_2L

the least electronegative element would typically go in the center

DPatel_2L

Nitrogen cannot have an expanded octet.

DPatel_2L

It is due sunday night.

DPatel_2L

Yes for that series n1=1

DPatel_2L

The ones on Khan academy work for me!

DPatel_2L

Yes it would have 4 sig figs in this case.

DPatel_2L

To get this you would divide total energy by the threshold energy.

DPatel_2L

They have an inversely proportional relationship, so as one increases the other one decreases.

DPatel_2L

Yeah I had the same question hopefully not too long.

DPatel_2L

For our uses yes it is.

DPatel_2L

On the formula sheet, the italicized one is the frequency.

DPatel_2L

I would use the constants that are given on the sheet.

DPatel_2L

Each TA has their own policy so I would check with them.

DPatel_2L

I am watching the lectures and taking notes, and also going over the module and textbook questions.

DPatel_2L

False because and increase in frequency means and increase in energy.

DPatel_2L

Each question will be worth different amounts of points.

DPatel_2L

Yes they both are the same.

DPatel_2L

The fact that frequency has to be a positive value.

DPatel_2L

A higher frequency has a shorter wavelength and vice versa.

DPatel_2L

multiply by 1*10^-9

DPatel_2L

The test should specify what units the answer should be in. If not meters is most likely okay.

DPatel_2L

Extensive means that it depends on the amount or size of the substance (volume). Intensive remains the same regardless of the amount of matter there is (density).

DPatel_2L

They basically mean the same thing but have different units.

DPatel_2L

There is no one right way to balance, and it depends on the equation to determine the fastest way to balance.

DPatel_2L

It does not matter when balancing equations, but you should be writing the state of matter that they are in the equations.

DPatel_2L

Yes they can be the same. However the molecular cannot be smaller than the empirical.
