Hi, I am doing a chemistry course through correspondence and am not sure what they want me to answer for this question.
The question states:
Answer the following questions using the information in the table below.
(Melting and boiling points are in Celsius)
Element Melting Point Boiling Point Molar Volume STP
A ====== -189 ====== -186 ====== 22.4 L
B ====== -100 ====== -35 ====== 22.4 L
C ====== -7 ====== 58 ====== 2.6*10-2
D ====== 30 ====== 2240 ====== 1.2*10-2
E ====== 44 ====== 280 ====== 1.7*10-2
F ====== 660 ====== 2450 ====== 1.0*10-2
G ====== 3410 ====== 5930 ====== 1.0*10-2
Here are the questions with my answers so far:
a)Which elements are likely to be metals?
b)Which elements are gases at STP?
For this I assume that elements A and B which have boiling points of less than 0 degrees celcius will be gases at STP.
c) Which element is most likely to be a non-metallic solid?
d) Which elements are liquid at 200 C?
Well for this I think it would be D and E as they are the only elements with a melting point of less than 200 that have not yet turned into gases(unlike A,B, and C which are already gases before hitting 200)
e) Which elements are likely to conduct well in the solid form?
I think that it would be the metals but since I don't know A (which elements are metals) I can't actually know which elements those are.
If someone could tell me if I got the ones I did right and explain to me how to find the others I would be very grateful.
