Vermilion, a very rare and expensive solid natural pigment that has been used to print artists' signatures on works of art, is m

Anon25 [30]

To solve for moles use molar and volume:

M = mol/L

0.02700 m= mol/(.75 L)

mol = .036 mol of Hg(NO3)2

The proportion of Hg(NO3)2 to the Mercury that is used to create HgS is 1:1 so solve for the moles of Mercury used. So:

.036 * (1 Hg(NO3)2 / 1 Hg) = .036 moles of Hg used to make HgS

The proportion of Mercury to HgS is 1:1, as an alternative of doing the obvious math you can conclude that .036 moles of HgS will be produced because you're given .036 moles of Hg and an excess of S. Use the molar mass of HgS to determine how many grams will be produced.

.036 moles * 232.66 g/mol = 8.37576 grams of Vermilion is produced.

0.448 g of an unknown diprotic acid is dissolved in about 60 mL of water in a beaker. The solution is transferred to a 100.00 mL

liq [111]

According to the Question:

We initially had 0.448 grams of the unknown diprotic acid, which was added to about 60 mL of water and that solution was added to a 100 mL flask and filled to the 100 mL mark

The above is as mentioned in the question, our 0.448 grams of diprotic acid is basically diluted to 100 mL [it's volume has been increased to 100mL]

but the amount of the acid is still the same

Which means that we now have 0.448 grams of the diprotic acid in a 100mL solution

Percent of the diprotic acid that will be present in the Erlenmeyer Flask:

From this 100 mL solution, 25 mL is transferred to the Erlenmeyer Flask

Which means that (25/100) * 100 = 25 % of the 0.448 grams of diprotic acid is present in the 25 mL sample

Mass of di-protic acid in the 25 mL solution:

Since 25% of the initial amount remains in the final solution,

Mass of the diprotic acid in the final solution = 0.448 * 0.25

Mass in the final solution = 0.112 grams

Therefore, 0.112 grams of the di-protic acid will be present in the Erlenmeyer Flask

Where would electrons in the d sublevel be found? Only in the n = 3 energy level in energy levels 3 possibly in any energy level

oksano4ka [1.4K]

<h3>Answer;</h3>

only in the n = 3 energy level

<h3>Explanation;</h3>

The atom of a chemical element is made up of sub-atomic particles which are the neutrons, protons and electrons. The neutrons and protons occupies the nucleus of an atom while the electrons occupy the energy levels.
The first energy level (n=1) of an atom occupies a maximum of two electrons because it has only an S-orbital which can only have two electrons.
The second energy level (n=2) can have a maximum number of 8 electrons, since it contains, one S- orbital which can hold two electrons, and a p-orbital which can accommodate six electrons.
The third energy level (n=3) can have a maximum number of 18 electrons, because it has the S-orbitals which holds 2 electrons, the p-orbital which holds 6 electrons and the d-orbital which holds 10 electrons.
