Answer:

Explanation:

The correct answer is 19, 20 DHDP is more polar than DHA. This is as a result of the presence of two hydroxyl groups.

Calculate the mass of atoms of carbon and 3 molecules of hydrogen

PSYCHO15rus [73]

The mass of atoms of carbon and 3 molecules of hydrogen : 18 g/mol

<h3>Further explanation </h3>

An atomic mass unit ( amu or "u") is a relative atomic mass of 1/12 the mass of an atom of carbon-12.

The molar mass(molecular mass-formula mass-molecular weight(MW)) of a compound is the sum of the relative atomic mass (Ar) of the constituent elements of the compound

Can be formulated :

M AxBy = (x.Ar A + y. Ar B)

The mass of atom of Carbon(C)⇒Ar = 12 g/mol

The mass of 1 molecule of Hydrogen - H₂(MW) : 2 g/mol

The mass of 3 molecules of Hydrogen : 3 x 2 = 6 g/mol

So the mass of atoms of carbon and 3 molecules of hydrogen :

$\tt 12+6=18~g/mol$

Enter the electron configuration for the ion most likely formed by phosphorus. Express your answer in the order of orbital filli

Bingel [31]

Answer:

[Ne] 2s2 2p3

Explanation:

Phosphorus will most likely have an ion that will be 3- because it wants to have a full outer shell. Thus, the elctron configuration is: 1s2 2s2 2p6 3s2 3p3.
