Thiazoles have anti-tumor and anti-viral
but most thiazole compounds are
flavourings. If it is combusted
air the products are carbon dioxide,
water, hydrogen sulphide (H2S) and nitrogen.
What is the balanced reaction? [8
What is the RMM of thiazole? [2
What is the fuel-air mass ratio? [5
What is the oxygen depletion? [4
What is the yield of CO2? [2
What is the yield of H2O? [2
What is the yield of N2? [1
For ideal combustion, what is the yield
of carbon-monoxide? [1 mark]
may assume the
composition of air is 21% O2 and 79 % N2. A periodic table is provided overleaf, should
you need one.
