A.simple cubic and face-centred cubic parameters
B.cubic and rhombohedral
C.cubic and tetragonal
D.hexagonal and monoclinic
P.have these cell
Q.are two cell systems
R.have only two crystallo-graphic angles of 900
S.belong to same crystal system
answer:
A-P,S
B-P,Q
C-Q
D-Q,R
plz explain me all the answers

What does the P statement mean "have these cell''?????
Well, I am telling the other answers.
A-Yes, they belong to same cell system(cubic). So, Q. And they have more than 2 90 degree angles. SO it cant be R.
B- They are 2 different cell systems and I hope U know abt the angles in all the 7 cell systems.
C- Again, 2 different cell systems.
D- again 2 different cell systems. And U must know the angles in all the 7 crystal systems.

@kane
the question is incomplete,
option P is
these have cell parameters a=b=c
and alpha=beta=gamma.
CHEERS...!!!
|
PROGRESS ISN'T MADE BY EARLY RISERS OR HARD WORKERS, BUT BY LAZY PEOPLE TRYING TO FIND EASIER WAY TO DO THE SAME.....SO BE LAZZZZYY!!!! |
