All the elements of the Periodic Table apart from hydrogen and helium are synthesised in the explosion of a supernova.
"explode as supernovae". These are called Type II supernovae and sometimes a neutron star is formed, not a black hole.
No. The most massive stars will leave behind a black hole.
No. The Big Bang was the origination of the universe; a black hole is the death of a star. Answer The big bang was an explosive expansion of space-time from a singularity, marking the beginning of time and space. Supernovae are exploding giant stars that form (and explode) millions or billions of years after such things as Big Bangs. The Big Bang was not a true explosion, but an enormous expansion. Supernovae are hugely closer akin to explosions.
Silver is an alloy consisting of gold and minerals including argentite and chlorargyrite. Copper, gold, lead and zinc are byproducts of silver.
It is common for a process that produces a desired product to also produce something that is not needed - and this is called a byproduct. If a byproduct has no use it may be pumped away, which may not a very environmentally friendly thing to do.
Shocks from supernovae are the explosions of massive stars.

no
supernovae are classified by the lines in their spectra (which indicate which elements are present). type I supernovae have no hydrogen lines, having been caused by the explosion of a star with no hydrogen envelope. type II supernovae have hydrogen lines, indicating that the exploding progenitor star had retained a significant amount of its hydrogen before its supernova. type I supernovae are further classified based on the presence of silicon lines, which are present in type Ia supernovae but not types Ib and Ic.
Black holes do not create supernovae. Black holes are created from a supernovae.
Supernovae are massive explosions that occur when a star uses up its gas and explodes so they will only occur once a star has died.
