What is Garfield's favorite part of chemistry? Lanthanum-Sulfur-Silver-Sodium

Trigonal bipyramidal is a very symmetrical shape so individual dipole-dipole moments cancel and there is no net dipole moment.

The prefix is used when there is one ligand type in the complex ion. It would probably be best to include it to be as specific as possible.

H2O has a zero net charge because it has the same number of protons and electrons overall. However, it is highly polar at the hydrogen and oxygen ends.

Tyler Vu 4I

Resonance will increase the stability of the conjugate base so the acidity will be increased as well. A larger atom can accommodate a negative charge better so the base will be more stable and the acid will be stronger. If an atom has a larger electronegativity, it will be less inclined to share ele...

The number to the left of the decimal point does not affect significant figures. This is important for the log calculation.

Ligands with more than one bonded atom (central metal atom) are considered polydentate. The prefixes mentioned are used with composite ligand names to avoid confusion.

The oxidation number is the number of electrons gained or lost by an atom of an element.

Tyler Vu 4I

If you draw the ring structure for the molecule, it is not symmetrical. This means it is polar.

Tyler Vu 4I

Water completely dissociates Na and Cl in salt and surrounds the atoms. The water donates electron pairs to Ni in NiCl and forms coordinate compounds.

The formula for ice is H2O^cubed

What do you call a pawsitive kitten? A cation

Tyler Vu 4I

The cis or trans property of the molecule depends on its polarity. This means cis or trans is more beneficial to a molecule depending on its function.

Tyler Vu 4I

The total moles produced minus the total moles of reactants yields the net moles produced during the reaction.

The first part is drawing the full Lewis structure diagram. Then the bonds and lone pair electrons on the central atom determine electron density.

Tyler Vu 4I

The values of the angles will be close to the ones you mentioned, but lone pair electrons and electron repulsion can change them slightly.

Tyler Vu 4I

Bond strength, the size of the compounds, molecular weight, and looking at the boiling points of similar compounds can all help determine which has a higher boiling point.

Tyler Vu 4I

An example of dipole moments occurs in the water molecule. The unequal sharing of electrons creates slightly positive and negative ends of the molecule.

Tyler Vu 4I

An example of dispersion forces is the non polar carbon dioxide molecule. Dispersion forces are considered Van der Waals forces, which occur between molecules. Hydrogen bonding can be observed between water molecules or N,O,or F bonds with hydrogen. These are important to know because they help us b...

You can still calculate the amount of product that each reagent produces and then the lowest one or ones would be the limiting reagent.

It is hard to memorize the states of matter for every equation but there are a lot of easy ones to remember. Understanding the states of the reactants can let us know if there is a precipitate out of solution.

I heard that oxygen and magnesium were going out and I was like OMg

I would post another chemistry joke, but all the funny ones argon

During midterm szn try to be like a proton and stay positive

Tyler Vu 4I

Losing four electrons would require a large amount of energy. The ionization energies for 4 electron removals with the elements of the group 14 would be very high. This way it would be more likely for them to gain 4 electrons to reach a stable state.

Tyler Vu 4I

There needs to be enough energy to eject an electron and give it kinetic energy once ejected. This is obtained when a photon has enough energy and the light has surpassed the threshold frequency.

Tyler Vu 4I

The question will give a value or values of something with sig figs. The lowest number of sig figs in the given value(s) should be used for the answer.

Tyler Vu 4I

Since kg is the SI unit, we would want to use that over grams.
