The empirical formula of the above compound is CH2Cl. empirical formula mass is 12 + (1x2) + 35.5 = 49.5
n= molecular mass/ empirical formula mass =98.96/49.5 = 2
Hence molecular formula is C2H4Cl2

Orbit :
An orbit is a well defined circular path around the nucleus in which the electrons revolve.
It represents the planar motion of an electron around the nucleus.
Orbital :
1.An 39 orbital is the three dimension space around the nucleus within which the probability of finding an electron is maximum (upto 90%).
2.It 14 represents the three dimensional motion of an electron around the nucleus.

Answer : The amount of carbon dioxide formed is, 76.93 g
Solution : Given,
Mass of methane = 80 g
Molar mass of methane = 16.042 g/mole
Molar mass of carbon dioxide = 14.026 g/mole
First we have to calculate the moles of .
Now we have of calculate the moles of carbon dioxide.
The balanced chemical reaction is,
Form the reaction, we conclude that
1 mole of methane react to give 1 mole of carbon dioxide
5.485 moles of methane react to give 5.485 moles of carbon dioxide
Now we have to calculate the mass of carbon dioxide.
Mass of carbon dioxide = Moles of carbon dioxide × Molar mass of carbon dioxide
Mass of carbon dioxide = 5.485 moles × 14.026 g/mole = 76.93 g
Therefore, the amount of carbon dioxide formed is, 76.93 g

1 mole NaOH is equivalent to 40 gm of NaOH.
Molality can be defined as the number of moles of solute in 1000 gm of solution.
Thus 5 molal aqueous NaOH solution contains, [ (5 x 40) = 200 ] gm NaOH.
Thus water present in the solution = (1000 - 200) = 800 gm
Moles of water present = (800 / 18) = 44.45
Thus the mole fraction of NaOH = (moles of NaOH / Total moles in solution) = (5 / 5 + 44.45) = 0.101

Covalent bond: The bond formed by mutual sharing of valency electrons in order to get stable electronic configuration of nearest inert gas is called covalent bond. Generally this bond is formed between non metals.
Based on type of atoms participated in the bonding, covalent bond is classified into two types. They are (i) polar covalent bonding
(ii) Non-polar covalent bonding
(i) Polar covalent bond: The bond formed between atoms of different electronegativity is called polar covalent bond. Ex: HCl, HF, HBr, H₂O, NH₃…etc
(ii) Non –polar covalent bond: the bond formed between atoms of similar electronegativity is called non-polar covalent bond. Ex: H₂, O₂, N₂, Cl₂…etc.
In a covalent bond shared pair of electrons is known as Bond pair. Bond pair is represented by a line.
Based on number of electrons shared between the atoms the covalent bonds are classified into three types: Single covalent bond, Double covalent bond and Triple covalent Bond.
Examples of Covalent Bond:
Hydrogen molecule is formed by the sharing of one electron pair (single bond) between two hydrogen atoms.
Oxygen molecule is formed by the sharing two electron pairs (double bond) between two oxygen atoms.
Nitrogen molecule is formed by the sharing of three electron pairs (triple bond) between two nitrogen atoms.

Avogadro Law
- It states that equal volumes of all gases under the same conditions of temperature and pressure
contain equal number of molecules. Mathematically,
V ∞ n
V = k4n
- The number of molecules in one mole of a gas = 6.022 ×1023
- This is termed as Avogadro constant.

N2>N2->N2+.
Nitrogen is an electronegative atom. It can manage an added negative charge easily.
But N2 + will be highly unstable.
Obviously N2 is most stable in given options.
so above order is correct order of their stability.
