Define a salt bridge.

a) a pathway composed of salt water, that ions pass through.
b) a pathway in which no ions flow.
c) a pathway between the cathode and anode in which ions are reduced.
d) a pathway between the cathode and anode in which ions are oxidized.
e) a pathway by which counterions can flow between the half-cells without the solutions in the half-cell totally mixing.

Answer : The correct option is, (E) A pathway by which counterions can flow between the half-cells without the solutions in the half-cell totally mixing.

Explanation :

Salt bridge : It is a type of laboratory device that is used to connect the reduction and oxidation half cell of a electrochemical cell.

The function of salt bridge in the cell is to maintain the electrical neutrality within the internal circuit because the electrons are moving from one half cell to another half cell.

It is made up with salt like

Hence, the correct option is, (E)

the answer is d : ) have a good da

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
