Answer:

Explanation:
At same temperature and same number of moles, Using Boyle's law
Given ,
V₁ = 10 mL
V₂ = 20 mL
P₁ = 5.85 kPa
P₂ = ?
Using above equation as:

Answer:
Low-energy reactants become high-energy products.
Explanation:
In electrolysis, you are forcing a reaction to occur that otherwise wouldn't happen.
You are pumping energy into the system and converting low-energy reactants into high-energy products.
B is wrong. Nature tends to run downhill energetically, so high-energy reactants tend to form low-energy products spontaneously.
C and D are wrong. If an element is unreactive, it stays unreactive, and vice versa. You can't change the nature of an element.
