1) True
2) No , Now it's RE language.
REC=Turing Computable
When we say some function f(x) is computable then we basically means that there exists an algorithm to do the computation of that function. And when there exists an algorithm then we have answer for YES as well as NO(for member and non-member of language)and in that way the language becomes REC(recursive).
RE=Turing Acceptable=Semi Decidable=Turing Recognizable=Turing Enumerable
If some language is accepted by Turing machine then
Members of the language will halt in final state and Non-members may halt in non-final state or hang.
