Answer:
³₂He
Explanation:
From the question given above, the following equation was obtained
²₁H + ²₁H —> ¹₀n + __
Let ᵇₐX be the missing part of the equation. Thus, the equation becomes:
²₁H + ²₁H —> ¹₀n + ᵇₐX
Next, we shall determine b, a, and X. This can be obtained as follow:
2 + 2 = 1 + b
4 = 1 + b
Collect like terms
b = 4 – 1
b = 3
1 + 1 = 0 + a
2 = 0 + a
a = 2
ᵇₐX => ³₂X => ³₂He
Thus the equation is:
²₁H + ²₁H —> ¹₀n + ᵇₐX
²₁H + ²₁H —> ¹₀n + ³₂He
The missing part is ³₂He
The formula for boiling point elevation is:
deltaT = (Kb)(m), where m is molality of moles solute per kilogram solvent
1.305 = 3.630m
m = 0.3595 = moles/kg solvent
Since we have 1 g of chloroform solvent, this is equivalent to 0.001 kg.
The number of moles is 103 mg or 0.103 g, divided by the molar mass (MM).
0.3595 = (0.103/MM) / 0.001
0.0003595 = 0.103/MM
MM = 286.51 g/mol
Therefore, the molar mass of retinol is 286.51 g/mol
Answer:
<h3>Since we know that carbon atoms tend to make four bonds, each carbon atom will have the number of hydrogen atoms that are required for four bonds. This compound contains 16 hydrogen atoms for a molecular formula of C8H16.</h3>

The chemical formula depends on the type of acids it is. Acidic rain is a complex mixture of nitrous, nitric, sulfurous and sulfuric acids which all combine to lower the pH.
