I hope they also analyze Enrico Pallazo's performance during the Queen's visit.

Bleach breaks down to chlorine, which in turn reacts with ammonia to form chloramine. Mustard gas has sulfur and cannot be synthesized this way.

Chlorine based bleach is just one of the things that has the label "Bleach" in your household cleaning aisle.

The only sulfur containing bleaches in that list are potassium persulfate and sodium hydrosulfite. Neither contains chlorine.

Furthermore, the synthesis of mustard gas is non-trivial. Those two chemicals are not enough to put the sulfur on a carbon chain.

Turing machine has unbounded memory. There is a difference between unbounded and unlimited memory: You can extend the tape as needed, but at any given step of computation, the used space is finite.

A Turing machine with bounded memory is called linear bounded automaton. Although LBA is less powerful than a Turing machine in the absolute sense, it is not trivial to form a problem that a Turing machine could decide but a LBA could not.

The difference is that with LBA you can determine if the program will end or not, as you can check all of the finite states it can have.
