Well since covalent bonds are strong and diamonds contains a lot of covalent bonds, it makes the diamond's melting point and boiling point very high.

Answer: 3M
Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
n = moles of solute 
= 0.6 moles
= volume of solution in ml= 200 ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution will be 3M.
Explanation:
Air borne pollutants are usually very light particles that are usually carried in the air in the atmosphere. Some of these pollutants can be carried far away and some are found close to their sources.
Some of the factors are:
- Wind pressure: if wind pressure is low, pollutants will not be carried far away. In this situation, the particles will be blown and carried over a short distance from their sources. When wind pressure is very high, pollutants will be carried extensively into farther areas.
- Pollutants can be trapped in snow. In a snowy area, when pollutants reach sky high and enters condensed water in the atmosphere, they can become super cooled into ice and fall back within the same area where they are formed.
- Rain water can also cause pollutants to be dispersed within a short area. Pollutants can mix with rain water and carrier back to the area where they were originally formed.

Alfred Wegener
proposed the continental drift theory in
four reasons. One, he hypothesized that the continents were once a giant
continent. Two, he observed that there are fossils found of the same kind in
the different locations. Three, he found that the edge of opposing continents
somehow fits if they are combined, almost like a puzzle. And four, there are
glacial scars that are left behind by a larger glacial continent. His greatest
weakness of Alfred Wegeners’ continental drift theory was he could not explain
what kind of force that caused this continents to move far from each other.
