HCL has a greater bond length making it easier for H+ to disassociate making it a stronger acid.
Polarizing power has to do with a cations ability to distort an anions electron cloud. Smaller cations usually have a larger polarizing power.
F- is a Lewis base. Anions are usually bases.
It only applies to kinetic energy. For example the energy of a photon is measured by plank's constant times it's frequency.
For momentum, either velocity or mass will usually be given. A question might ask you to solve for a missing variable.
The Ph of a strong acid is lower than that of a weak acid, however the concentration of H+ is greater.
The bond angles of a seesaw would be less than 120 degrees between the equatorial bonds, and less than 90 degrees between the axial and equatorial bonds.
The hybridization orbital of a trigonal planar is sp^2 since it has three regions of electron density. A trigonal pyramidal would have a hybridization of sp3 since it has four regions of electron densities.
It says on the website that Bonding from 3.12 to the end of chapter 3 and Molecular shape and structure 4.1-4.7 will be included in the test. As for the number of questions, I'm not sure but I'd say anywhere from 5-8 if it's like the previous tests.
Pretty sure it'll be cumulative, but with more questions on recently learned topics.
I think it would be helpful to memorize the bond angles respective to the molecular shape.
A compound that is polar has a greater electronegativity difference (considered ionic) versus one that is nonpolar. These types of compounds form dipoles.
The radius increases down a group since the additional shells are further from the nucleus. It decreases down a period because as electrons start filling the same shell the increasing difference in charge causes electrons to be pulled closer to the nucleus.
it's pretty easy to count the difference by just looking at the structure.
The formula shows the there is a limit on the accuracy of our knowledge of an electron's position and momentum at the same time.
The atom with the lowest ionization level is at the center of the Lewis structure. These are usually the ones on the left of the periodic table.
You can eliminate B since the wavelength of the radiation would increase if frequency decreased, for D the energy of the radiation would decrease not increase if the frequency decreased. Since speed is a constant A can be ruled out as well. That leaves us with C.
Topic: Energy levels of orbitals?
Re: Energy levels of orbitals?
The energy of the orbitals goes according to their distance from the nucleus. So f would have the highest energy level and d,p, and s would follow.
Topic: What is the equation used for?
Re: What is the equation used for?
Heisenberg's equation measures the uncertainty in the position and momentum. When conducting an experiment, trying to measure the position of an electron can disrupt the outcome of the velocity, thus affecting momentum.
The moles are not equal but the number of atoms of each element in both the reactant and product side are. The moles indicate the amount of compounds that can be created from the given atoms.
There can only be one limiting reagent in a reaction. Since the limiting reagent determines the amount of product that can be created, once it has been used it would not make sense that another reactant could limit an already determined product.
rounding atomic weight/mass can lead to small discrepancies so it's best not to do so until you've reached your answer. Usually I try to include at least three numbers after the decimal for accuracy when rounding to find the number of moles.
