Selenium falls in the same column with oxygen therefore it has the same number of valence electrons with oxygen which is 6. It fills the 3d orbital but only 4s and 4p are counted. The electronic configuration is [Ar]3d^10 4s^2.
SN1 is a substitution reaction
with n being the nucleophilic substitution an 1 represents a unimolecular
reaction. Because the given molecule on the central carbon is sterically
hindered, the rate of carbocation formation is increased dramatically. It will
make the OT (leaving group) to leave and a nucleophile (nucleophilic attack) will
react to the carbocation.
Q=m(c∆t +heat of fusion + heat of evaporation)
m= 44g
c= 4.186 J/g.C
∆t= 107-(-8) =115 C
heat of fusion= 333.55 J/g
heat of evaporation=2260 J/g
Q=44(4.186*115 + 333.55 + 2260)
Q= 135297.36 J
Answer:
Exothermic
Explanation:
Nuclear fission means splitting, so there is a lot of energy being <em>released</em>.
