Explanation:
It is known that like dissolves like which means a polar compound will be soluble in a polar solvent. And, a non-polar compound will be soluble in non-polar solvent.
Ionic compounds are soluble in polar solvent like water. For example, is an ionic compound and it is readily soluble in water.
2-butanol () is also a polar compound and it will also dissolve in water but to a lesser extent as compared to magnesium chloride.
Whereas both methane and propane are non-polar in nature. But as propane is larger in size as compared to methane so, it will be slightly more soluble in water as compared to methane.
Thus, we can conclude that the given substances are placed in order from most soluble in water to least soluble in water as follows.

Two things plants need to have in order to stay in orbit and rotate is speed and less velocity.
NaHCO3 is the right answer
Answer:- Atomic number for sulfur is 16 and it's electron configuration is 
. Here, there are total for electrons in 3p and the set of quantum numbers for these 4 electrons would be as..
For the first electron of 3p-
n = 3, l = 1, ml = -1 and ms = +(1/2)
for the second electron of 3p-
n = 3, l = 1, ml = 0 and ms = +(1/2)
for the third electron of 3p-
n = 3, l = 1, ml = +1 and ms = +(1/2)
and for the fourth electron of 3p-
n = 3, l = 1, ml = -1 and ms = -(1/2)
The element has 83 electrons
