Lightning rods are mounted on top of tall structures to protect them during thunderstorms. If lightning strikes, it will hit the rod and be directed to the ground through a wire, instead of passing through the structure. What type of substance should be used to make a lightning rod, and why?

Answers

Here we have to point out the necessary character of the substance needed which are used as lightning conductor.

The substance should have the following properties:

High electricity carrying capacity and less resistant.

High melting point

The substance should have high electricity carrying capacity or the resistance is less so that the electricity generated during the lightning easily conducted to the ground

The substance should have high melting point so that during lightning the generated high temperature cannot disrupt the material.

Answer:The lightning rod should be constructed of a metal, which is an inorganic substance.

Metals are good conductors of electricity.

Given the balanced ionic equation:3Pb2+ + 2Cr ==> 3Pb + 2Cr3+
What is the number of moles of electrons gained by 3.0 moles of lead ions?
(1) 5.0 mol (3)3.0 mol
(2) 2.0 mol (4) 6.0mol

Answers

Answer : The correct option is, (4) 6.0 mol

Explanation :

The given balanced ionic equation is,

$3Pb^(2+)+2Cr\rightarrow 3Pb+2Cr^(3+)$

In this reaction, lead undergoes reduction and chromium undergoes oxidation.

Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.

Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.

Half reactions of oxidation and reduction are :

Oxidation : $2Cr\rightarrow 2Cr^(3+)+6e^-$

Reduction : $3Pb^(2+)+6e^-\rightarrow 3Pb$

From the reduction reaction, we conclude that 6 moles of electrons gained by the 3 moles of lead ions.

Hence, the correct option is, (4) 6.0 mole

answer: 6......................
