Answer:

C. Fe in Fe₂O₃

Explanation:

<em>The sum of the oxidations states times the atomicity is equal to the charge of the molecule.</em>

A.

2.H + 1.P + 4.O = -1

2.(1+) + 1.P + 4.(2-) = -1

P = +5

B.

2.Cr + 7.O = -2

2.Cr + 7.(-2) = -2

2.Cr = 12

Cr = +6

C.

2.Fe + 3.O = 0

2.Fe + 3.(-2) = 0

2.Fe = 6

Fe = +3

Fe has the lowest oxidation state (+3).

How many grams of magnesium acetate are in 8.95x10^23 formula units?
Natasha_Volkova [10]

Answer:

211.63 g.

Explanation:

  • Particles could refer to atoms, molecules, formula units.
  • <em>Knowing that every one mole of a substance contains Avogadro's no. of molecules (NA = 6.022 x 10²³).</em>

<em><u>Using cross multiplication:  </u></em>

1.0 mole → 6.022 x 10²³ molecules.

??? mole → 8.95 x 10²³ molecules.

  • The no. of moles of magnesium acetate = (8.95 x 10²³ molecules) (1.0 mole) / (6.022 x 10²³ molecules) = 1.486 mol.

∴ The grams of magnesium acetate are in 8.95 x 10²³ formula units = n x molar mass = (1.486 mol)(142.394 g/mol) = 211.63 g.
