Because its structure is drawn by dots which can't describ its structure.
Answer:
the covalent molecule has OA.A
From the ideal gas law
pv=nRT , n is therefore PV/RT
R is the
R is gas constant =62.364 torr/mol/k
P=500torr
V=4.00l
T=500+273=773k
n={(500 torr x 4.00l)/(62.364 x773k)}=0.041moles
the number of molecules=moles x avorgadro costant that is 6.022x10^23)
6.022 x 10^23) x0.041=2.469 x10^22molecules
The correct answer is internal.
A solid substance whose components like molecules, atoms, or ions are aligned in a highly ordered microscopic composition producing a crystal lattice, which extends in all the directions is known as a crystalline solid or a crystal.
On the other hand, the noncrystalline solid substance in which the atoms and molecules are not aligned in a definite lattice pattern is known as an amorphous solid. Such solids comprise plastic, glass, and gel.
1mile/13min * 1min/60sec * 63360in/1mil = 63360in/780sec = 81.23 in/sec
