Answer:
A. maintain electrical neutrality in the half-cells via migration of ions
Explanation:
Salt bridge -
For an electrochemical reaction , involving an anode and a cathode , both the electrodes are connect via a salt bridge to complete the circuit for the reaction .
One of the very important use of a salt bridge is to maintain the electrical neutrality of the respective half cells , which is achieved by the movement of ions .
Hence , from the given options , the correct option is ( a ) .

Answer:
n = 1.075 moles
Explanation:
Given that,
Mass of oxygen = 34.4 gram
The molar mass of oxygen gas = 32 g/mol
We need to find the number of moles of oxygen. We know that,
No. of moles = given mass/molar mass
So,
So, there are 1.075 moles in 34.4 g of Oxygen gas.
4x − 8x= −3
Step 1: Simplify both sides of the equation.
4x−8x = −3
4x + −8x= −3
(4x + −8x) = −3 (Combine Like Terms)
−4x = −3
Step 2: Divide both sides by -4.
−4x / −4
−3
- / −4
so your answer will be x= 3/4
