a)
Write a balanced equation for the reaction.
b)
Classify the reaction as either redox or metathesis.
c)
If 3.00 of pure sulfuric acid were added to 21.00 g of solid nickel (II) cyanide, how
many litres of hydrogen cyanide gas, measured at
742.0 mmHg and 22.0
o
C, would be produced? Assume the reaction goes
to 100 % completion.
