Oxygen cannot be broken down into a simpler substance by using chemicals :) Hope this helps and the other answer gets removed :)
Methane (CH4) forms the molecular solid.
<u>Explanation:</u>
- The molecules which are held together by intermolecular forces are called molecular solids. It is maintained by solids rather than bonds. The force which holds these solids are weaker than other solids.
- It consists of discrete molecules and the cohesive force which binds them together is Vanderwall's force, dipole-dipole interaction and hydrogen bonding. They are held together by an ionic bond or covalent bond.
- The weak intermolecular forces have relatively low melting points which are less than 300 degrees Celsius.
- Organic solvents dissolves Molecular solvents. Many of the molecular solids are soft electrical insulators with low density.
2 NaCl --------> 2 Na + Cl₂
2 mol * 23 g Na = 46 g
2*35,5 g Cl = 71
46 g Na --------- 71 g Cl₂
460 g Na -------- ?
mass ( Cl₂) = 460 . 71 / 46
Mass (Cl₂) = 32660 / 46
m= 710 g of Cl₂

Answer:
The correct answer is - option C. Law of superposition.
Explanation:
According to the law of superposition states that within a sequence of layers of natural sedimentary rock without any disturbance, the oldest layer is lies under the younger layers with ascending order in the sequence.
If a sedimentary rock has 4 layers as a, b, c and d where the younger layer d would be on top and the oldest layer a would be at the bottoms.
Thus, the correct answer is - option C.
