Your question isn't quite clear, but if you're wondering if a chemical is polar or non-polar, you simply draw a VSEPR sketch and draw arrows where the bonds are. Only draw arrows between atoms, NOT between an atom and a lone pair of electrons. The arrow should point to the most electronegative atom (you should be given an electronegativity scale). Afterwards, you add up the arrows as vectors, and look at the sum of the vectors. If the sum is zero (CH4 is a good example), the chemical is non-polar. If the sum is a vector, the chemical is polar (H2O, or water, is polar).
Answer:
Frost Wedging - Hot and dry
Clay Formation - Cold and Wet
Dissolving - Cold, and dry
Explanation:
The frost wedging happen when the climatic condition is hot and dry. The dry weather compensates the heat and the rock wedging happens quickly. For clay formation the weather has to be cold and wet. The cold weather will make the sand indulge with rock particles resulting in the clay formation.

1 pound of coffee is said to yield 50 cups of coffee
So we need to find the pounds of coffee beans required to produce 250 cups
so if 50 cups need 1 pound of coffee beans
therefore 250 cups need - 1/50 x 250 = 5 pounds of coffee beans
since we have to find the amount of coffee beans needed in kg, we have to convert pounds to kg
1 pound = 0.45 kg
So if 1 pound is equivalent to 0.45 kg
then 5 pounds are equivalent to - 0.45 kg/pound x 5 pounds = 2.25 kg
therefore 2.25 kg of coffee beans are required
