There are 0.400 mol Br₂ in the sample..
Mass of Br₂ = 20.5 mL Br₂ × 3.12 g Br₂/1 mL Br₂ = 63.96 g Br₂.
Moles of Br₂ = 63.96 g Br₂ × (1 mol Br₂/159.81 mol Br₂) = 0.400 mol Br₂
Answer:
This question is so confusing, I'm sorry
Answer:
It is an example of Exothermic reaction.
Explanation:
It leads to release of HEAT as can be seen water is given in gaseous form.
