Answer:This is what's known as a metal displacement reaction: the lead substitutes for the copper and ends up precipitating out of solution as insoluble lead (II) sulfate. ... The weight of copper deposited was 15.86gm.
Explanation:
The new volume of air trapper in the cylinder is determined as 116.56 mL.
<h3>
New volume of air in the cylinder</h3>
The volume of air trapper in the cylinder is determined from Boyle's law;
P₁V₁ = P₂V₂
where;
- P₁ is initial pressure = 1.08 atm
- V₁ is initial volume = 145.7 mL
- P₂ is new pressure = 1.25 x 1.08 atm = 1.35 atm
- V₂ is new volume = ?
V₂ = (P₁V₁)/P₂
V₂ = (1.08 x 145.7)/1.35
V₂ = 116.56 mL
Thus, the new volume of air trapper in the cylinder is determined as 116.56 mL.
