Answer:
Comets develop a fuzzy, cloud-like shell called a coma, as well as a tail.
Explanation:
This feature of a comet develops when the celestial body passes close to a star such as the sun. The ice around the nucleus of the comet sublimates forming the coma around the comment (when hit by light photons as observed from the earth). The tails are also formed by the ice being pushed a bit behind the comet by light pressure.

Answer:
The water of crystallization of the intermediate analyte is 5.
Seeing as the question does not provide the value for weight of the salt on further heating (at 120° C), you can apply the steps in this explanation to attain that value.
Explanation:
XSO4.7H2O → XSO4 + 7H2O
8.1g 4.9g
8.1 - 4.9 = 3.9g of water evaporated
The ration of water to salt is:
XSO4 : H2O
grams : 4.9 3.2
moles: 72 + 32 + (16×2)=136 (1×2)+ 16= 18
0.036 0.178 (divide both sides by smallest value)
1 4.93
∴ <u>water of crystallization of intermediate is 5.</u>
