Mg²⁺ + 2Cl⁻ = MgCl₂
n(Mg²⁺)=0.25 mol
n(Cl⁻)=2n(Mg²⁺)
n(Cl⁻)=2*0.25=0.50 mol
Answer:
2–Ethyl–3–methlypentanal.
Explanation:
To name the compound given in the question above, we must observe the following:
1. The functional group of the compound is Alkanal i.e Aldehyde,
—CHO and it is located at carbon 1.
Note: the aldehyde functional group is always at carbon 1 and there will be no need to state it's position in the compound.
2. The longest continuous carbon chain is 5 i.e pentane. But the presence of the functional group will replace the –e at the end of pentane with –al, making the name to the pentanal.
3. The substituents attached are:
a. Ethyl, CH2CH3 at carbon 2.
b. Methyl, CH3 at carbon 3.
4. Combine the above to get the name of the compound.
Therefore, the name of the compound is:
2–Ethyl–3–methlypentanal.
Answer:
The ovaries and the testes
Explanation:
<em>The organs responsible for the development of secondary sex characteristics would be the ovaries and the testes.</em>
<u>Both ovary and testes are associated with the sex organs in the body and are responsible for the synthesis of hormones such as androgen and estrogen. While the latter (estrogen) is produced by the ovary, the former (androgen) is produced by the testes.</u>
More specifically, both androgen and estrogen are hormones responsible for the growth of hairs in areas such as the armpit and the pubic regions of the body.
<em>The correct options are </em><em>the ovaries</em><em> and </em><em>the testes</em><em>.</em>
I’m pretty sure the correct answer is D.
