No it can be at any temperature. Only the Nernst Equation that is E=E(standard)- (.05916)/n)*logQ needs to be at 298K.

If volume increases and temperature decreases, pressure MUST decrease to satisfy the PV=nRT equation, so there's actually no way pressure would have been constant. With that said, the above post is correct.

On page 102 of the course reader, there are more IUPAC naming examples of alkenes. The third example is named 1,6-dichlorocyclohexene. Why is it not 1,2-dichlorocyclohexene?

When naming a cyclohexane that has 1 ethyl and 2 methyl substituent on either the 1st or 3rd carbon, would you put the 1 with the ethyl and the 3 with the methyl or the other way around? (Is it 1-ethyl-3,3-dimethyl-cyclohexane or 3-ethyl-1,1-dimethyl-cyclohexane?)

When comparing the K of two different reactions, does the larger K mean a faster or slower reaction?

Q: Why was the mole of oxygen molecules excited when he left the singles bar?
A: He got Avogadro's number!

An atom says, "I think I lost an electron." His friend asks, "Are you sure?" and the atom replies, "I'm positive."

From Chapter 8 Number 11: A piston confines 0.200 mol Ne(g) in 1.20 L at 25 degrees C. Two experiments are performed. (a) The gas is allowed to expand through an additional 1.20 L against a constant pressure of 1.00 atm (b) The gas is allowed to expand reversibly and isothermally to the same final v...

I have many chemistry jokes... I'm just afraid they won't get a good reaction.

Have you heard the one about a chemist who was reading a book about helium?

He just couldn't put it down

Eliza_Beglari_2L

Typically the units should be in Joules/atom.

Since polyprotic acids can donate more than one proton there is more than one reaction and more than one K_a value found. After finding each K_a of each reaction, why do you multiply the K_as together to get the overall K instead of adding them?

Eliza_Beglari_2L

yes because pH+pOH=14

What do you do with a sick chemist?
You can't helium, you can't curium, so you might as well barium.

Can someone please give the answer and explanation to the question below?

Arrange the cations Rb⁺, Be²⁺, Sr²⁺ in order of increasing polarizing power. Give an explanation of your arrangement.

Eliza_Beglari_2L

Yes, the angles are slightly less than 90 and 180 degrees

Why are Ionic bonds' Lewis structures look different from the normal molecules lewis structures? For example, in our course reader the lewis formula for potassium chloride on page 76. Usually the normal lewis structures do not have brackets, what do these brackets for the ionic bonds mean?

Eliza_Beglari_2L

Are spdf referred to as subshells or orbitals? Do orbitals mean m_ℓ?

Eliza_Beglari_2L

I dont trust atoms, I heard they make up everything.

I make horrible science puns too but only periodically.
