How do you determine conjugate acids and conjugate bases from a regular acid and base?

taiyeojeikere-3C

When transferring the name of a coordination compound to it's chemical formula name, does it matter if the anion is in the front or back of the equation(outside of the parentheses?)

taiyeojeikere-3C

When naming a coordination compound, how do we calculate the oxidation state for the compound when naming it?

taiyeojeikere-3C

To determine which molecule has the greater ionic character, are you supposed to base it off of the ionic radius? For example which has a greater ionic character between CH4 or CF4.

taiyeojeikere-3C

Are there any other molecules that are like N2O with N as the central atom?

taiyeojeikere-3C

What is the difference between sigma and pi bonds and what does it mean by component orbitals?

taiyeojeikere-3C

How can you determine the difference between intermolecular forces using shape and polarity?

taiyeojeikere-3C

How do you determine which forms of an isomers are polar and have the largest dipole moment?

taiyeojeikere-3C

Can you only determine bond angles by drawing the molecular shape of that molecule?

taiyeojeikere-3C

How do you determine the different bond angles in an OSCl molecule, and why does it not correspond to the bond angles in an SOCl2 molecule?

taiyeojeikere-3C

Are we only supposed to know the three molecular shapes we learned in lecture on Friday, or are there more?

taiyeojeikere-3C

How do you determine which bonds are which lengths and if they are shorter or longer?

taiyeojeikere-3C

When drawing Lewis Structures, would the structure be marked incorrect if you don't draw the bonds to have the correct angles like 120 degrees, etc.?

taiyeojeikere-3C

Would the calculations, En=-hR/n^2 and -hR((1/n-final^2)-(1/n-initial^2)) give the same results when calculating change in energy levels?

taiyeojeikere-3C

What exactly are radicals and how can we tell what species are radicals?

taiyeojeikere-3C

How do we calculate the electronegativity of an atom, or is it something that we have to estimate?

taiyeojeikere-3C

So when looking for the ground state and given a electron such as s2-, I remove two electrons from the last energy level to get the ground state configuration?

taiyeojeikere-3C

When trying to figure out the amount of valence e- in an atom, are we supposed to figure out the electron configuration first? And is the last shell the valence shell?

taiyeojeikere-3C

What are the different trends in the periodic table, and how would we be tested on them?

taiyeojeikere-3C

Can someone explain what the particle-in-a-box model is (for a hydrogen model and treating the atom as a one-dimensional box pf length 150 pm) , and how would I use it to predict the wavelength of radiation emitted from different energy levels ( a)falls from the level with n 5 to that of n 4 b)same ...

Does the Cartesian axes only refer to the axes of the orbitals in a 3D model?

taiyeojeikere-3C

Is there a calculation to solve the next number in a wavelength in a Balmer series or???
Question: Lines in the Balmer series of the hydrogen spectrum are observed at 656.3, 486.1, 434.0, and 410.2 nm. What is the wavelength of the next line in the series?

taiyeojeikere-3C

What's the difference between the photoelectric effect and atomic spectra. Both require light to shine on a metal and detect the motion of the electrons. The photoelectric effect tells if the wavelength is small enough to move the electron to the positively charged detector. And does the atomic spec...

taiyeojeikere-3C

How do I know how to write a chemical reaction from the name of a compound such as dimethanesulfonate (I looked this up for an example)? Do I focus on the prefix, or is this something that should be obvious from looking at a periodic table?

taiyeojeikere-3C

All you really need to know is how to balance an equation and how to write/balance a chemical equation from the name of the compound.

taiyeojeikere-3C

Can someone please explain to me why the answer for #3 When the frequency of electromagnetic radiation decreases... is C) the event of the change in the electrical field at a given point decreases?

taiyeojeikere-3C

Does solving a stoichiometry problem use the same steps as limiting reactant because my notes are a bit confusing on the topic?

taiyeojeikere-3C

On the problem for fundamental E.1, why does the radius , 144 pm, have to be doubled before I can complete the problem correctly?
