Answer: Option (5) is the correct answer.
Explanation:
It is known that more is the number of carbon atoms linearly present in a compound more will be its boiling point. This is because then more number of intermolecular forces are present within the atoms of a compound.
Hence, lesser is the number of carbon atoms present less will be the intermolecular forces present in it. Therefore, more readily the compound will evaporate into the atmosphere.
Thus, we can conclude that given compounds are ranked in increasing rate of evaporation as follows.

Answer:
The mass of reactants and products for the reaction is this:
- 92 g Na, 32 g O₂, 124 g Na₂O
which is not a choice from the list.
Explanation:
4 moles of Na reacts with 1 mol of oxygen to produce 2 moles of sodium oxide.
Na = 23 g/m
4 moles are (4 . 23) = 92 g
O₂ = 32 g/m
It's a diatomic molecule (each O is 16 g/m)
Na₂O = 62 g/m
2 mol of sodium oxide will be (2 .62) = 124 grams
The mass of reactants and products for the reaction is this:
- 92 g Na, 32 g O₂, 124 g Na₂O
which is not a choice from the list.

Please provide answer options. :)
Water with high levels of calcium ions is referred to as hard water. While hard water has health benefits, this type of water has economic implications in the industry and households too. In the industry, hard water can cause a breakdown of equipment such as boilers, over time. In the household, too much soap is used when washing with hard water than soft water. Therefore hard water requires to be softened before industrial use. Economically, this increases the cost of production.
