25. There is a problem solvable by Turing machines with two tapes but unsolvable by Turing machines with a single tape 26. The language L = {(M, w) | M halts on input w} is recursively enumerable 27. The language L = {(M,w) | M halts on input w is recursive ne language L = {a"o"c" | n 2 1} in linear time 24. Nondeterministic Turing machines have the same expres siveness as the standard...

(9 pts 3 pts each) For each of the following languages, name the least powerful type of machine that will accept it, and prove your answer. (Hint: a finite state automata is less powerful than a pushdown automata, which in turn is less powerful than a Turing Machine.) For example, to prove a language needs a PDA to accept it, you would use the Pumping Lemma to show it is not regular, and then build the PDA or CFG that...

Bonus. Let QA denote a new class of abstract machines that act just like PDAs, except that the stack is replaced with a queue. Argue informally that QAs are at least as powerful as PDAs, in the sense that any language accepted by a PDA is also accepted by some QA. Hint: show that you can simulate a stack by using a queue.

8. Which of the following statements justifies why LiAlHs is a more powerful reducing agent than its isoelectronic counterpart NaBH4? i. NaH is a strong nucleophile, meaning the direct attachment of the hydride to li. The dipole moment of LiAIHs is higher than that of NaBHa, making its hydride ii. NaBHs is just as much of a strong reducing agent, with the ability to reduce a the sodium ion will make the hydride more nucleophilic like LiAIH more nucleophilic. nitrile...
