Substances that have exactly the same molecular composition and molecular weight but different molecular structures, and thus different properties, are called ( ). 3. The general formula for alkane molecules is ( ), and the general formula for alkene molecules is ( ). 4.

1. The steam drum of the cracking furnace is located above the quench boiler; water flows through the quench boiler via thermosiphon action to generate saturated steam. 2. Substances that have exactly the same molecular composition and molecular weight but different molecular structures, and thus different properties, are called (isomers). 3. The general formula for alkane molecules is (CnH2n+2, where n>=1), while the general formula for alkene molecules is (CnH2n, where n>=2). 4. When increasing the production load of the pyrolyzer, the oil feed rate should not exceed (110%) of the design value; when reducing the production load, it must not be lower than (70%) of the design value. 5. The basic modes of heat transfer are (conduction), (convection), and (radiation).
4. When increasing the production load of the pyrolyzer, the oil feed rate should not exceed （ ） of the design value; when reducing the production load, it must not be lower than （ ） of the design value. 100% vs 70% – there is a slight difference; what is it? ? ? What happens if too much oil is injected?

Impressive, really:victory:
