Explanation:
,Answer:
kinetic energy, gamma decay, it becomes less stable by repositioning its particles
Explanation:
Answer:
The right solution is:
(a) 2459.74 J/degree C
(b) 3271.769 KJ/moles
Explanation:
According to the question,
(a)
The heat capacity of the calorimeter will be:
= 
= 
= 
(b)
The change in temperature will be:
= 
= 
The amount of heat released will be:
= 
= 
or,
= 
Moles of benzene combusted will be:
= 
= 
hence,
The heat combustion for 1 mol of benzene will be:
= 
= 
Both AM and FM radio signals have the same frequencies at times.
