Answer:
The main reason that NO, has a higher boiling point than CO is that NO has a larger molar mass.
The main reason that NH3 has a higher boiling point than CH4 is that NH exhibits hydrogen bonding.
The main reason that CS2 has a higher boiling point than CO2 is that CS2 has a larger molar mass.
Explanation:
The larger the molecular mass, the greater the surface area of the molecule and the greater the magnitude of dispersion forces. Hence, among nonpolar molecules, increase in molecular mass leads to a higher boiling point due to stronger dispersion forces.
Though CO and NO possess dipole-dipole forces, NO has a greater molar mass than CO, hence it has a higher boiling point than CO.
NH3 exhibits intermolecular hydrogen bonding hence it has a much higher higher boiling point than CH4 irrespective of the fact that their molar masses are close in magnitude.
The organism was once a clam and most likely became a fossil after being buried by silt in its watery environment after death. Might need more clarification on what exact answer you need.

Answer:
6 stages
Explanation:
Given:
Copper ore contains:
4.3 wt% water
10.3 wt% CuSO₄
85.3 wt% rock
Feed rate = 11.7 tons per hour
solution produced is to be 10 wt% copper sulfate
90 wt% water
Now,
The CuSO₄ supplied through the feed = 10.3 wt% CuSO₄ × Feed rate
= 0.103 × 11.7
= 1.2051 tons per hour
also,
At each stage 2 tons of solution is collected
therefore,
The CuSO₄ collected in each stage
= weight of solution × 10 wt% copper sulfate
= 2 tons per hour × 0.1
= 0.2 tons per hour
also,
98% of the CuSO₄ is to be recovered
thus,
the amount of CuSO₄ to be recovered
= 0.98 × CuSO₄ supplied through the feed
= 0.98 × 1.2051 tons per hour
= 1.180998
Therefore,
The number of stages required = 
= 
= 5.90499 ≈ 6 stages
