Isn’t ionization energy removing an electron from the gaseous state?

The first ionisation energy is the energy required to remove the most loosely held electron from one mole of gaseous (!) atoms to produce 1 mole of gaseous (!) ions each with a charge of 1+. So dont they both have to be gases…?

^That’s what I thought, and I think we’re right haha

What did y’all put for HCl tf question. It asked if HCl was a weak acid and if cl was very electronegative

F T @debate4ever

And for true false. In the first column I got no ttce and in second I got a couple. Anyone else did the same?

@debate4ever
FT

^FT

Does anyone remember how many TTCEs they got? I had 3.

there were no CEs in the first column, and i only put 2 in the second column but i think there are three (the one about Li, Na, and K i put TT but everyone is saying its TTCE).

@baller55 yeah I only got 2 CE. I only put TT for the Li one.

!!! @alldaboston you’re the first person to side with me!
I think that its not CE because i can refute the second statement as being an explanation of the first with Hydrogen bc it has the same number of valence electrons and doesn’t have the same chemical properties.

I think the whole T T CE section is sometimes subject to debate, since some may say that something is an explanation but something else may be more of an explanation but whatever

Can someone post what they think the curve is gonna be?

I think it’ll be something like this

85 - 800
84 - 800
83 - 800
82 - 800
81 - 790
80 - 790
79 - 790
78 - 780
77 - 780
76 - 770
75 - 770
74 - 760
73 - 760
73 - 750

is that too lenient?

@baller55 is that raw score or number correct?

Raw acore

What was the answer to the question with sig figs? and the one with enthalpy of formation

54 was the answer I think

Hmm, I got 54.3… But I don’t know my sig figs that well.

i think it was 54 because 2 sig figs

Aren’t sig figs different for adding though? And I think we were adding values right?

Edit: oh wait nvm
