<h3>Answer:</h3>

           ΔE  =  2.18 × 10⁻²¹ kJ

<h3>Solution:</h3>

Using Bohr Energy Equation,

                                    ΔE  =  - R (1/nₐ² - 1/nₓ²)

Where;

           R  =  Rydberg's constant  =  2.18 × 10⁻¹⁸ J

           nₐ  =  Infinity  =  ∞   (electron removed from H atom)

           nₓ  =  1   (Ground state of H atom)

Putting Values in equation 1,

                                    ΔE  =  - 2.18 × 10⁻¹⁸ J × ( 1/∞² - 1/1²)

                                    ΔE  =  - 2.18 × 10⁻¹⁸ J × ( 0 - 1)

                                    ΔE  =  - 2.18 × 10⁻¹⁸ J × (-1)

                                    ΔE  =  2.18 × 10⁻¹⁸ J

                                    ΔE  = 2.18 × 10⁻²¹ kJ

baherus [9]

Answer:

camphor sublimates salt is soluble in water while sand does not sublime and does not dissolve in water you first heat the mixture in a beaker covered with a watch glass camphor will then accumulate on the watch glass then you dissolve the remaining mixture of sand and salt salt will dissolve forming a salt solution then you filter using a filter paper and a beaker the residue on the filter paper is sand while the filtrate is salt solution you then heat the salt solution so that it can evaporate leaving salt particles thus you will have obtained salt sand and camphor
