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:
Because of the existence of isotopes.
Answer: 2
Explanation: Greenhouse gases are very important in keeping our planet just right. If we have too many Greenhouse gases it would be too hot, but we can't eliminate all of them or it will be too cold
