Descriptive Chemistry + Basic Inorganic Chemistry Educational Game

I'll first start

Why does Ti4+ not have color while Ti2+ and 3+ does have color?
How is this? I'm not really good with naming

well it's because the color is due to the spectrum formed in the d orbital. However, since Ti's electron configuration is [some noble gas] 3d2 4s2. When it loses four electrons it has no d orbital electrons so no spectrum of electrons. Thus no color.

What are the basic assumptions to the ideal gas law?

i think one is that the volume of each individual particle is negligible

It's just PV = nRT is the Ideal Gas Law but the assumptions? Hmmm.

Okay.. What is the Aufbau Principle?

Intermolecular forces are also negligible

what is the nernst equation at equilibrium?

is that Aufbau's principle?

electrons are placed in orbitals in increasing order.

Yea and the Polli (Sp) Exclusion Principle says that no two electrons can have the same quantum numbers.

nernst equation is basically playing around with G0=G+RTIn(q)
they changed it for electrochem.
I think
E0=E-RT/nF*InQ

Ok didn't mean to disparage anyone or anything.
anyways what's an ideal liquid?

well it's basically if you have liquids they have the same characteristics like bonding, polarity etc. It isn't that clear compared to the ideal gas. btw it's according to Rauolt's law

Q is the reaction quotient (tell me if i screwed up)

Explain why the addition of an electron to a chlorine atom is an exothermic process and the addition of an electron to a magnesium atom is an endothermic process.
