The element chlorine occurs in nature as a mixture of two isotopes. Chlorine-35 has an atomic mass of 34.969 amu and makes up 75.77% of chlorine atoms.
Chlorine-37 atoms make up the remaining 24.23% of all chlorine. The average
atomic mass of chlorine from the periodic table is 35.4527 amu. Calculate the
atomic mass of Cl-37 atoms.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

50.23 i believe is correct but don't quote me on that.
