Because it is a gas, it reacts with nearly everything (difficult to design and prepare a container for it), it is extremely corrosive and extremely poisonous.
It is not ever used in school chemistry laboratories (the word "normally" in the question is not quite right!)
No it has 9, I only know this from studying chemistry at school and from textbooks.
I believe but could be wrong, that LiCN is Lithium Cyanide.Source - Im a high school chemistry student
· Francium Sulfide (Fr2S) · Francium Phosphide (Fr3P) · Francium Bromide (FrBr) · Francium Sulfite (Fr2SO3) · Francium Hydrogen Oxalate (FrHC2­O4)
Because the school is to cheap to pay for heating
The Lewis diagram for chlorine fluoride (ClF) would show Cl as the central atom with one bond to F. Cl would also have 3 lone pairs around it to complete its octet, while F would have 3 lone pairs around it. This arrangement would satisfy the octet rule for both chlorine and fluorine.

The motto of Technological University of Pereira School of Chemistry is 'School of Chemistry'.
Chemistry is a learning discipline and is learned at school.
The complete subject is "The chemistry teacher at your school."
for school teacher Rs 28000 & for collage chemistry teacher 90000
because this is the right place to do an experiment
Chemistry.
Only in special controlled laboratories.
Technological University of Pereira School of Chemistry was created in 1968.

"The new chemistry teacher at your school is my friend's cousin?" Some people would say the complete subject to be "Chemistry teacher" or "new chemistry teacher", but it's not. The complete subject is just "teacher". "Chemistry" and "new" are both adjectives.
