Q1:
A quantity of KCN pellets are placed into a compartment placed below.
A quantity of concentrated H2SO4 is poured down a tube that leads to a
small holding tank directly below the compartment containing the KCN
pellets. A screen is opened. Following this, a switch activates the
KCN pellets to drop into the sulfuric acid, initiating a chemical
reaction as follows:
2KCN(s) + H2SO4(aq) → 2HCN(g) + K2SO4(aq)
What does this chemical reaction indicate?

Q9:
The use of the term which describes this method appears to be a
mockery of the concept of an actual "secular" marriage. At the time
Napoleon and Josephine were married in March of 1796, few people
considered the religious ceremony at all necessary, people got married
with so much facility, and in so simple a manner, that the
exaggeration is merely verbal which states that X was completed by
dancing round a tree of liberty, and that the divorce was effected by
dancing round the same tree of liberty backwards. Jean-Baptiste
Carrier is popularly cited as having devised this method. Name the
method.
