Worked practice questions
Which reaction with hydrogen is explosive even in the dark and cold?
- Fluorine
- Chlorine
- Bromine
- Iodine
Show answer and solution
Correct answer: A. Fluorine
Fluorine is the most reactive halogen and reacts violently with H2 without light or heat.
Iodine reacts with hydrogen only partially, forming what?
- A strong acid
- An equilibrium
- A polymer
- An ionic solid
Show answer and solution
Correct answer: B. An equilibrium
HI splits back into H2 and I2, so the reaction reaches an equilibrium.
