The H₂O is the formula of the chemical specie while the (s), (l) and (g) tell us the state in which it is present, where s is solid, l is liquid and g is gas.
<span>the structure(s) of the product(s) you would expect when this ether is cleaved with hi can be Methyl propyl ether

N=1 shell contains 2 electrons.
n=2 shell contains 5 electrons.
n=2 is the outermost shell. Therefore there were 5 electrons before sharing.
6 electrons are being shared between 2 nitrogen atoms.
Pair of electrons form a covalent bond. Therefore 3 pair of electrons will form 3 bonds.
The rate of gas effusion or diffusion is inversely proportional to the square root of molar mass
molar mass of neon is 20
let the molar mass of unknown gas be y
155/76=sqrs of y/20
square both side to remove the square root sign
155^2/76^2 =y/20
by cross multiplication y={(24025 x 20)/5776}=83.18
the gas is krypton since 83 is one isotope of krypton
