Answer:

At equilibrium, solid iodine sublimes to give purple-coloured iodine vapour, which also condenses back to the solid iodine.

Explanation:

Sublimation is the process by which a solid changes state directly from the solid state to a gaseous state without going through the liquid state. Solid iodine is one of such solids that undergo sublimation.

  At equilibrium,            I₂ (solid)  ⇔  I₂(gaseous)

From the question,

As heat is gradually applied to the sealed container,  solid iodine begins to sublime and the purple-coloured vapour of iodine is observed.

As the heating continues, the intensity of the purple colour intensifies as more of the solid iodine undergoes sublimation.

At equilibrium however, it is observed that the intensity of the purple coloured iodine vapour remains the same.

This is so because at equilibrium, solid iodine sublimes to give purple-coloured iodine vapour, which also condenses back to the solid state

What is the empirical formula of a compound with 35.94% aluminum and 64.06% sulfur
Sunny_sXe [5.5K]

                        Al                                               S

    1)            <u>  35.94  </u>    =1.33111                     <u>  64.06 </u>     = 2.001875

                       27                                               32

    2)          =    <u> 1.33111 </u>                                 = <u>  2.001875  </u>

                     1.33111                                         1.33111

                 

    3)         =   ( 1 ) × 2                                     =    ( 1.5 ) ×2

    4)         =  2                                                =   3

                     Empirical Formula = Al2S3

1) Divide the percentage given in question by the Relative Atomic Mass (RAM)

of the given elements.

2) When you find the answers of the first part of question, divide these once again but this time, by the lowest number you found in part 1.

3) and 4) Write down the values. If you get a decimal which is in between 0.3-0.7 (including the 0.3 and 0.7), you cannot make it a whole number by rounding of. Therefore, multiply the decimal with a whole number until you get a whole number as your answer. In this question, when you multiply 1.5 by 2, the answer is 3 which is a whole number. Multiply the other whole number by the same number as that you multiplied for 1.5. And use these numbers in part 4 to make the empirical formula which is Aluminium Sulfide (Al2S3)

Hope this helps you :)))
