Answer:
you should consider waterproofing. depending on the climate in your area, you need to apply multiple layers of waterproofing in the roof for it to support vegetation. you should also confused the types of plants. the types of plants is important for the success of your roof. if you live in a dry area, you don't want to choose plants that can live in dry areas without drying out.
Elemental sulfur occurs as octatomic molecules, 63.2 g F2 are needed to react completely with 17.8 g S8 to produce SF6 .
<h3>What is octatomic molecules?</h3>
When stable under normal temperature and pressure circumstances, an octatomic element is a chemical element that has eight atoms arranged in a group. Sulfur, symbol S8, is the classic example, but red selenium is also an octatomic element that is stable at ambient temperature.
A molecule with eight sulfur atoms has a puckered ring or crown structure. Sulfur is in an octet state when it contains two more electrons than the six in its outermost shell. Sulfur has an atomic number of 16 and an electrical configuration of 2, 8, 6.
Other elements (S, Se, and Te) exist as octatomic solids while oxygen is a diatomic gas at normal temperature.

Answer: Option (4) is the correct answer.
Explanation:
Heat of vaporization is defined as the heat energy which is necessarily added to a liquid substance in order to transform the quantity of the substance into a gas.
For example, in there will be presence of strong hydrogen bonding and in order to break this bond high amount of heat energy is required.
Whereas , and are all covalent compounds which are bonded together by Vander waal forces. As these forces are weak in nature hence, they require less amount of heat energy to convert into vapor state.
Hence, they have low value of . Also, Ar is a noble gas and it has only Vander waal forces. So, it will also have low value of .
Therefore, we can conclude that out of the given options have the highest .
