Answer:The purpose of the salt bridge in an electrochemical cell is to <u>maintain electrical neutrality in the half-cells via migration of ions </u>
Explanation:
A salt bridge is a u-shaped tube or filter paper bridge type laboratory device used to connect the oxidation and reduction half-cells of a galvanic/voltaic cell. it maintains electrical neutrality in the half cells thereby preventing the cell from having imbalance of charges in the flow of electrons moving from one half cell to another.
Answer:
A. Oxygen is an element because its most basic unit is a single type of atom.
Explanation:
Oxygen is the chemical element with the symbol O and atomic number 8.
How long does it take for the planet to revolve around the sun?
Answer:
D. 40 % increase
Step-by-step explanation:
r = k[A]²/[B]
The rate is inversely proportional to [B]. If [B] is doubled, the rate is halved.
We must double this rate to get back to the original.
The rate is directly proportional to [A]².
2 = [A]₂/[A]₁² Take the square root of each side
√2 = [A]₂/[A]₁ Multiply each side by [A]₁
[A]₂ = √2[A]₁
[A]₂ = 1.41[A]₁
We must increase [A] by 41 %.
To be honest I don’t even know
