Answer:
<em>Zinc nitrate is an inorganic chemical compound with the formula Zn(NO3)2. This white, crystalline salt is highly deliquescent and is typically encountered as a hexahydrate Zn(NO3)2•6H2O. It is soluble in both water and alcohol.</em>

correct me if im wrong please
The hydronium ion concentration of a pH = 9.2 of solution is 6.3 × 10⁻¹⁰M.
<h3>How do we calculate pH?</h3>
pH of the solution is define as the negative logarithm of the concentration of the hydronium ion as:
pH = -log[H⁺]
Or [H⁺] = ![10^{-pH}](https://tex.z-dn.net/?f=10%5E%7B-pH%7D)
Given that pH value = 9.2
On putting values, we get
[H⁺] =
= 6.3 × 10⁻¹⁰M
Hence required concentration of hydronium ion is 6.3 × 10⁻¹⁰M.

Answer:
For CH3CH2OH the OH stretch between 3550-3200 cm-1
For CH3CH2NH2 a pair of bands at 3500 and 3400 cm-1 respectively corresponding to the N-H stretch
Explanation:
CH3CH2OH is ethanol. This is a primary alcohol characterized by the by the -OH (hydroxyl) group. A strong broad IR absorption in the 3550 - 3200 cm-1 corresponds to the O-H stretch and indicates that the compound could be an alcohol or it has an OH functional group.
CH3CH2NH2 is ethylamine. This is a primary amine characterized by the -NH2 (amino) group. The presence of a primary amine shows up as a pair of medium strength absorption features corresponding to the N-H stretch, one at around 3500 cm-1 and the other around 3400 cm-1.
the element hydrogen atom is made up of oxygen atoms.
