Calcium has valency 2 and cl is diatomic molecule and 2 elctron is transferred to cl2 from calcium.ionic bond generally ocuurs in between metal and non metal.so due to transfer of electron, there exist ionic bond between cacl2
Answer: 0.00488K
Explanation: using the general gas equation
(P1V1)/T1 =(P2V2)/T1
Substitute
2*6/273= 3*3/T
Simplify
T= 0.00488°K
When you need heat to make reaction happen it is endothermic.
If heat was on the right side then type of reaction would be exothermic.
An example of the substnce would be steel
Explanation:
Typically, only one element is present, so all atomic radii are the same. -Metallic bonding is not directional. -Nearest neighbor distances tend to be small in order to lower bond energy.
