Answer: The isotopic abundance of Cl- 37 is 0.2424.
Explanation:
Mass of isotope - 35 = 34.96885 amu
% abundance of isotope -35= x% =
Mass of isotope - 37 = 36.9659 amu.
% abundance of isotope-37 = (100-x)% =
Formula used for average atomic mass of an element :
Therefore, the isotopic abundance of Cl- 37 is 0.2424.

Answer:
a: chemical change because the change cannot be reversed.
b: physical change because the action can be reversed.
c: chemical change.
d:chemical change.
any change that cannot be reversed is a chemical change and any change that can be reversed is a physical change.
