Answer: a) anode
b) positive
c) cathode
d) anode to cathode
Explanation:
Galvanic cell is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.
In the galvanic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode. Thus the electrons are produced at anode and travel towards cathode.
Due to loss of electrons at anode, positive charge in concentrated in anode and negative charge is concentrated in cathode. To balance these charges , positive ions or cations from salt bridge move towards cathode and negative ions or anions from salt bridge move towards anode.
The balanced two-half reactions will be:
Oxidation half reaction :
Reduction half reaction :
Thus the overall reaction will be,
![M(s)+X^{n+}(aq)\rightarrow M^{n+}(aq)+X(s)](https://tex.z-dn.net/?f=M%28s%29%2BX%5E%7Bn%2B%7D%28aq%29%5Crightarrow%20M%5E%7Bn%2B%7D%28aq%29%2BX%28s%29)
According to the <span>Le
Chatelier's Principle, if a condition of system is changed, then the system try
to become equilibrium again by correcting that change.
N2(g) + 3H2(g) ⇄<span> 2NH3(g)
If H2(g) is added, then the concentration of H2(g) is high in the system. So
the system tries to reduce it and become to equilibrium
state. Hence to reduce that H2(g) the forward reaction is promoted. Then
Concentration of product, NH3 gas
is increased.</span></span>
Atomic mass of sodium is 22.9 g/mol
atomic mass of chloride is 35.45 g/mol
sodium chloride is 22.99 + 35.45= 58.44 g/mol
Answer:
I think it's D one. Because all others are wrong
