The destructive force of the wave is not felt while they are out at the sea but it is felt when they approach the shore.
<u>Explanation:</u>
When the waves are out in the ocean they are in deeper waters. Once they move towards the shore they approach shallow waters. This movement causes shoaling of the waves by which its amplitude increases.
When the wave reaches the shore its leading edge gets slowed down by coming in contact with the beach floor but its trailing edge which is still in deep water still moves rapidly. The wave thus gets compressed and its wavelength decreases. The amplitude of the wave then increases rapidly making the wave destructive.
Number of moles Aluminium sulfide
1 mole of sulfide contains 150 g
Therefore; 16.2/150
= 0.108 moles
The mole ratio of Al2S3 : Al(OH)3 is 1:2
Therefore; moles of Aluminium hydroxide will be;
= (0.108 × 2)
= 0.216 moles
But, 1 mole of Al(OH)3 contains 77 g
Therefore, the mass of aluminium hydroxide is
0.216 moles × 77
= 16.632 g
