The first question is why.
The second question is also why,
The third is how far are you willing to go towards the Sun to detonate the explosion.
The fourth is like the second - why,
The fifth is how would you deliver the payload, as a central insertion would be impossible - it would disintegrate before it reached to core.
The sixth - What sort of megatons - TNT, Semtex, C4, Nuclear?
The Seventh - What sort of rocket will you use to extend the payload?
The Eighth - Where in the Sun do you intend to detonate this payload.
The Ninth - I assume you have a good lawyer, as if you do kill the Sun, there will be a billion law suites coming your way.
At the end of the day, whatever the payload you imagine, there is not enough stuff on Earth to destroy the Sun. However if you could find 5 times the mass of the Sun in hydrogen, then we could have a party
Matter
The explosion ejected at least 5 cubic miles of rock, ash and pumice and was the equivalent of 200 megatons of TNT
well it would take approximately 49 earth days
it would take 15 years, if going at 20,000 mph.

5 it would be very easy
One
Surprisingly few ! The 'super powers' have enough nuclear weapons between them - to destroy humanity many times over !
Vinegar can destroy almost anything within a certain time frame, to destroy a penny it will take up to a few milliseconds
It is difficult to answer how many nuclear bombs it would take to destroy England due to the fact that there are a variety of different nukes. It would most likely take around a couple of dozen.
To destroy metal you would need to put it in extreme heat (fire) or cut it with a crystal saw. :)
It took minutes to destroy but years to build
That would depend on yields. Also simply killing all humans would take much much less.
There hasn't been a test on that yet, it would also depend on how big the warheads carried were.
Just one.
about 26 to 50
