Answer:

Explanation:
Hello,
In this case, for the given molarity and volume of such solution, the moles of sodium sulfate are computed below:

Now, by using the Avogadro's number, the ions result:

Best regards.
Battery or electrochemical cell
Explanation:
A battery is a power source that directs electrons from oxidation - reduction reactions to flow through a device to give electrical power.
- A battery is an electrochemical cell.
- Electrochemical cells are devices in which chemical reactions produce an electric current that is, chemical energy is turned into electrical energy.
- The reactions here are spontaneous redox reactions, hence electrons flows on its own in an external circuit.

Answer:
n = 0.207 mole
Explanation:
We have,
P = 1 atm
V = 5 liter
R = 0.0821 L.atm/mol.K
T = 293 K
We need to find the value of n. The relation is as follows :
PV = nRT
Solving for n,

So, the value of n is 0.207 mol.
Answer:
Electron: A negatively charged particle found circling or orbiting an atomic nucleus. An electron, like a proton is a charged particle, although opposite in sign, but unlike a proton, an electron has negligible atomic mass. Electrons contribute no atomic mass units to the total atomic weight of an atom.
Explanation:
0.250 L*3M=0.250 L*3mol/L= 0.750 mol
