Swimming pool structures and structural _____ [680.26(B)(1) and (B)(2)] shall not be used as a grounding electrode.
leonid [27]

A grounding electrode is any object that directly links to the earth. They are most times used to divert electricity from the elements.

  • Swimming pool structures and structural <u>reinforcing steel. 250.52(B)(3)</u><u>,</u> [680.26(B)(1), and (B)(2)] shall not be used as a grounding electrode.

In code 250.52(B)(3) it is clearly specified that the bonding grid and reinforcing steel that is related to a pool should not be used as grounding electrodes.

This is essential because when a metal that lies beneath a swimming pool is used as a grounding electrode, current from nearby electrical systems can be introduced into the pool.

This could cause the electrocution of anybody in the swimming pool at that time.

Write the balanced molecular and net ionic equations for the reaction between aluminum metal and silver nitrate. identify the ox
asambeis [7]

Well in this case, silver nitrate is reduced:

Ag<span>+  </span><span>+  </span>e<span>−  </span>→ Ag(s) ↓

 

Meanwhile, the aluminum is oxidized forming a positive ion:

Al(s<span>)  →  </span>Al<span>3+  </span><span>+  3</span>e−

 

To get the overall reaction,  we add the half equations so that the electrons are eliminated:

Al(s<span>)  +   3</span>Ag<span>+  </span><span>→  </span>Al<span>3+  </span><span>+  3</span>Ag(s)

 

And similarly:

Al(s<span>)  +  3</span>AgNO3(aq<span>)  →  </span>Al(NO3)3(aq<span>)  +  3</span>Ag(s<span>)</span>

[ 1.3 ] What is the concentration (%) of solute in the RBC (i.e., what is the concentration of all solute molecules combined?) A
ch4aika [34]

Answer:

0.9%

Explanation:

At the instance where you add RBCs to a solution of 0.9% NaCl, they will maintain their shape as well as their size, this is simply to indicate an equilibrium. That entails that the solution is isotonic to the RBCs. This must mean that the concentration of solutes on each side must be equal otherwise osmotic pressure would force water either in or out of the membrane. Therefore, one can also safely assume that RBC's also have a solute concentration of 0.9%.
