Magnesium has three isotopes. magnesium-24 has a percent abundance of 78.99% magnesium- 26 has a percent abundance of 11.01% what is the percent abundance of mangesium- 25?

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
