Answer:
MgCl2 > C4H9OH > CH4 > C3H8.
Explanation:
Alkanes do not form hydrogen bonds and are insoluble in polar solvents e.g water. The hydrogen bonds between water molecules are move away from an alkane molecule and this worsens as their Carbon chain / molecular weight increases.
MgCl2 is soluble in water. Water essentially breaks down the ionic crystal lattice and the resulting solution is slightly basic.
Alcohols are generally soluble in water and this is because of the -OH group and its ability to form hydrogen bonds with water molecules. As applied to alkanes, as the carbon chain in the alkyl group increases, the solubility decreases.
From the most soluble to the least soluble,
MgCl2 > C4H9OH > CH4 > C3H8.
I believe the answer is D. loess. The loess soil is a predominantly silt-sized sediment formed by accumulation of wind blown dust. This soil is highly porous, homogeneous, pale yellow and friable. One way of forming loess is from glaciers and that is why they contain glacially ground flour like clay and silt.
Answer: so the answer would likely be

Answer:
The mass of ammonia (NH3) that contains 
hydrogen atoms is 
g.
Explanation:
As 
atoms of hydrogen = 1 mole of the hydrogen atom
Therefore, 
atoms of hydrogen 
moles of the hydrogen atom.
Now, there are 3 moles of hydrogen atoms in 1 mole of ammonia 
.
As the mass of 1 mole of ammonia is 17g, so
when there are 3 moles of hydrogen atoms, then the mass of ammonia = 17 g
Therefore, when there are 
moles of hydrogen atoms, then the mass of ammonia 
g.
Hence, the mass of ammonia that contains hydrogen atoms is g.
