Re: Short Hand

Refer to the previous noble gas and put the name of that in brackets and then continue to write the configuration. Basically we just act as if the noble gas in the brackets acts as the configuration for the noble gas, so we would continue writing configuration as if we wrote the configuration up til...

Re: Ordering of s and d orbitals

In what situation could we order the 4s orbital before the 3d? (just for my own knowledge because I know that we should order the 3d before the 4s in this class)

Re: Intensity, frequency, and wavelength

The number of photons and intensity are proportional, so I think that if the intensity increases, the number of photons will increase as well.

Re: Percentage Yield HW Question

Since the actual yield depends on the limiting reactant (in this case, the ammonia), we do not need to know the amount of excess reactant (the hypochlorite). First, find how many moles of ammonia are present in 35 grams. Use that to find the proportional amount of hydrazine that should be produced. ...

Re: Understanding how to get whole #s [ENDORSED]

If you are solving from grams to mols, you can leave the number as is (2.44 mols is fine, you do not have to round). Hope this helps!

Re: 2 Limiting Reagents

It's also important to remember that even though the amounts of the reactants may be the same, we have to compare how many moles of each reactant are present, not the actual masses of the reactants.

States of Matter in a Chemical Equation [ENDORSED]

When writing out chemical equations, should we always include the states of matter of each of the reactants and products?
