Answer : The energy change for the reaction is CsCl is, 95 KJ/mole
Explanation :
The steps involved in the formation of :
(1) Conversion of gaseous potassium atoms into gaseous potassium ions.
= ionization energy of potassium = 419 kJ/mol
(2) Conversion of gaseous bromine atoms into gaseous bromine ions.
= electron affinity energy of bromine = -324 kJ/mol
The overall reaction will be:
To calculate the overall energy change the expression used is:
Now put all the given values in this equation, we get:
Therefore, the energy change for the reaction is CsCl is, 95 KJ/mole
Answer:
A hot air balloon floats because, the air inside of the balloon is more dense than the air outside the balloon. The air inside the balloon is a hotter temperature and has more kinetic energy as more molecules move faster. And has to be heated enough to carry the amount of passengers and it all depends on mass. The pressure of the outside air is supporting the hot air balloon by force and the fire uses its heat to makes the balloon air increase in temperature therefore making the balloon float up because heat rises. The air inside the balloon expands and has increased volume.
