To add to this, "iso" and "neo" should be included when alphabetizing, while "sec" and "tert" are not.

In naming compounds, which takes priority for the lowest number: a double bond or a functional group?

On a quiz or the final, is it acceptable to leave out the hydrogens when drawing line structures?

If given the initial concentration at t=0, then you can calculate k by using the equation $[A]=-kt +[A]_{0}$

Otherwise, you can calculate k by plotting the concentrations you have vs time and determining the negative of the slope as the equation shows.

Are liquid and solid reactants excluded in the rate law?

On a quiz or exam, would a negative voltage be acceptable? Or should it always be positive since that would be the favorable reaction?

An extensive property is a property that depends on the size of the sample. Heat capacity is an example of an extensive property since heat required depends on the amount of substance you have. On the other hand, an intensive property doesn't change regardless of the sample size. For example, if you...

NO2 has more atoms in the molecule compared to NO, and thus a higher molecular complexity. Heat capacity increases with molecular complexity. This is because there are additional vibrational modes within more complex molecules, allowing more heat to be absorbed.

From my understanding, the phase change from water to steam requires more heat than the phase change from ice to water. How would this difference be represented in a heating curve?

The atom with the lowest ionization energy/electronegativity goes in the middle of the structure. In P4, all the atoms have the same ionization energy/electronegativity, so there is no tendency for one atom to be the central atom.

Electron heteronuclear covalent bonds are covalent bonds between two different types of atoms. For example, O2 is not heteronuclear because it contains two of the same atoms, whereas CO is heteronuclear because it contains two different atoms.

First of all, these are the values that the quantum numbers can take: n: any positive integer l: n-1 m(l): -l < m(l) < 1 -l \leq m_{l} \leq l m(s): -1/2 or 1/2 For part b, you are already given n, l, and m(l). This means that m(s) can either be -1/2 or 1/2. So, only 2 electrons can have the quantum ...

Orbitals with higher l values are NOT better at shielding than orbitals with lower l values. Since the electrons in atoms with lower l values are on average closer to the nucleus (like the s orbital compared to the p orbital), they cancel out the positive charge of the nucleus, making the effective ...

The energy of light for a single photon is E=hv, where h is planck's constant and v is the frequency of the light/photon. Since power is how much energy is transferred per second, the power must be proportional to the number of photons emitted per second, n. Since each of these photons has an energy...
