Question

If A is true, write A. if B is true, write B. If both statements are true, write C. If both are false, write D. 

A. Ammonia has the same molecular and empirical formula

B. Ammonium has the same empirical formula as ammonia.

Answer 1

A is true because in the ammonia ratio of nitrogen to hydrgen is 1:3 so emipirical formula is NH$_3$ and same is the molecular formula.

B is false because in the ammonium ion ratio of nitrogen to hydrgen is 1:4 so emipirical formula is NH$_4^+$ which is defferent from ammonia.

So correct option is A
