Answer:
The minimum concentration of Cl⁻ that produces precipitation is 12.6M
Explanation:
The Ksp of PbCl₂ is expressed as:
PbCl₂(s) → Pb²⁺(aq) + 2Cl⁻(aq)
The Ksp is:
Ksp = 1.6 = [Pb²⁺] [Cl⁻]²
When Ksp = [Pb²⁺] [Cl⁻]² the solution begind precipiration.
A 0.010M Pb(NO₃)₂ is 0.010M Pb²⁺, thus:
1.6 = [0.010M] [Cl⁻]²
160 = [Cl⁻]²
12.6M = [Cl⁻]
<h3>The minimum concentration of Cl⁻ that produces precipitation is 12.6M</h3>
Oxidation of nitrogen to nitrogen oxide in the channel of a lightning:
N₂ + O₂ = 2NO
oxidation of natural nitrogen oxide and of nitrogen oxide of combustion gases to nitrogen dioxide:
2NO + O₂ = 2NO₂
nitrogen dioxide reaction with moisture of air or rain water:
4NO₂ + O₂ + 2H₂O = 4HNO₃
No because the light can only produce the color the manufacturer gave it and it is thin air unless the laser beam was able to make things on fire then the substance would be called a gas
