Whichof the statement are ture about the law of chemical combination?
A. Potassium combines with two isotopes of chlorine `.^(35)Cl` and `.^(37)Cl`) to form two samples of `KCl`. Their formation follows the law of definite composition.
B. Different proportion of oxygen in the varius oxidies of sulphur prove the law of multiple proportiens.
C. `H_(2) O` and `H_(2)S` contains `11.11%` hydrogen and `5.88%` hydrogen, respectively, whereas `SO_(2)` contains 50% sulphur. The above data prove the law of reciprocal proportions.
D. In the decomposition of `NH_(3), 2NH_(3) overset(Delta)rarr N_(2) + 3H_(2)`, the ratio of volumes of `NH_(3),N_(2)` and `H_(2)` is `2 : 1 : 3` The above data proves the Gay Lussac law.
