<span>(6.36x10^25)/(6.02*10^23) is approximately 105.6 moles</span>
A and B only because O2 and CO2 do not have dipole moments
Hey there!:
β-decay:
Unstable nucleus undergo β-decay in which a neutron is converted into proton , so
¹₀ n ----> ₁¹p + ₋₁⁰e ( Z + 1 )
The complete reaction is as follows:
²²⁷₈₉AC -----> ²²⁷₉₀ Th + ₋₁⁰e
Therefore , the daughter nucleus is : ²²⁷₉₀ Th
Hope that helps!
Answer:
They form crystals, they have really high boiling points, They have higher enthalpies of fusion and vaporize than an molecular compound, the are brittle
