Answer:
In solving this question it is important to note that entropy is referred to as the degree of randomness in a compound or system.
Entropy is highest in gas and lowest in solids
The order is given as:
Gas > Liquid > Solid
Another criteria is the more the elements in a compound, the more the entropy.
For example: KO3 has more entropy than KO2 due to the presence of more elements.
The last criteria is calculating their masses , the one with a greater mass has the higher entropy.
The option with the least entropy will be a solid. Al(s) and NaF(s) are both solids. NaF(s) has more elements in a compound which makes it have a higher entropy than Al(s). This means NaF(s) > Al(s).
The next to consider are the gaseous compounds which are HF(g) , SiF4(g) and SiH4(g). The least entropy will be HF(g) . This is because it has the least number of elements of the 3 compounds.
SiF4(g) and SiH4(g) have equal number of elements in a compound but the one with the highest mass is SiF4(g) because fluorine has a higher mass when compared to hydrogen. This means the compound with the highest entropy is SiF4(g).
The order of increasing entropy is given below:
Al(s) < NaF(s) < HF(g) < SiH4(g) < SiF4(g)
For the constituents of a mixture, they retain their individual properties meaning iron remains magnetic and sulfur remains a non metal and non metallic.
