Vedclass · Answer

(A) Mischmetal is an alloy consisting of a lanthanoid metal $(\approx 95\%)$,iron $(\approx 5\%)$,and traces of $S, C, Ca,$ and $Al$. Thus,statement $(a)$ is True $(T)$.
The symbol for Cerium is $Ce$,while $Cs$ is the symbol for Cesium. Thus,statement $(b)$ is False $(F)$.
The symbol for Cerium is $Ce$. Thus,statement $(c)$ is True $(T)$.
Therefore,the correct sequence is $(a)-T, (b)-F, (c)-T$.

Determine the correct $(T)$ and incorrect $(F)$ statements from the following:
$(a)$ Mischmetal contains lanthanoids and iron.
$(b)$ The symbol for Cerium is $Cs$.
$(c)$ The symbol for Cerium is $Ce$.
