The answer is option E. All of the above
Answer:
Explanation:
In S₈ , there are 8 single bonds which breaks up first . Energy absorbed
= 8 x 240 = 1920 kJ
In S₈ four double bonds of S₂ are formed . Let bond energy be x . In this process energy will be released . energy released in four S₂ molecules formed = 4 x
Given
1920 + 4x = 239
4x = 239 - 1920
x = - 420.25 kJ .
So bond energy of S₂ = 420.25 kJ .
Answer:
The correct answer is - at high pressure a huge amount of gases can be stored in less volume.
Explanation:
We already know that pressure is inversely proportional to the volume of gas which means if we increase the pressure the volume of gas becomes less.
P = 1/V
So in the scuba divers tank, the oxygen is filled at very high pressure so the high amount of the oxygen can be filled in less volume and which will last for longer than a normal pressure tank can last.
