Answer:
Fraction-of-occurrences of 115In isotope
Explanation:
As we know weight of 113 In isotope is equal to the sum of product of fraction-of-occurrences of two constituents isotopes and their atomic weight
------(1)
As we know sum of fraction-of-occurrences of two constituents isotopes is equal to one.
---------(2)
Substituting the given values in equation 1, we get
Substituting this value in equation 2 we get -
The type of bond that forms between two water molecules is Hydrogen Bond
I think it's the first and second option but I could be wrong because I don't know much about deserts :)
