CAIE IGCSE Chemistry 6.3.6 Sources of the Hydrogen Methane and Questions

Identify how nitrogen is separated from air and how hydrogen is produced from methane or natural gas for industrial ammonia manufacture.

Exam points

state that nitrogen is obtained from air, commonly by fractional distillation of liquid air
state that hydrogen is obtained industrially by reacting methane or natural gas with steam
identify the main raw-material sources for both Haber-process gases
select valid natural resources for each feedstock and reject unrelated sources
