Answer:
N=+2
O=-2
Explanation:
The compound NO is electrically neutral.
Lets assign the oxidation number of nitrogen to be N. The oxidation number of oxygen (-2) is then used as a reference.
For the compound to have a zero charge, sum of the oxidation numbers equals zero.
N+ (-2)=0
N=+2
O=-2

Answer is (3) - Pb²⁺.
<em>Explanation;</em>
Among the given choices PbCl₂ is insoluble in water. But it can be soluble in hot water. It appears as white precipitate. The Ksp of PbCl₂ is very small. That's why it is insoluble in water.
Fe²⁺ + 2Cl⁻ → FeCl₂ (soluble in water. Forms pale green color solution)
Mg²⁺ + 2Cl⁻ → MgCl₂ (soluble in water. Forms clear colorless solution)
Pb²⁺ + 2Cl⁻ → PbCl₂ (poorly soluble in water. Forms white precipitation)
Zn²⁺ + 2Cl⁻ → ZnCl₂ (soluble in water. Forms clear colorless solution)
Wait a second...I am sorry I don't know the answer but I have something to tell you.
It is not necessary that in alcohols, OH should be at the end of a chain .
It can be anywhere in the chain..
