Answer:

Sm (Samarium) = [Xe] 4f6 6s2

Explanation:

Noble gas electron configuration of Sm (Samarium) = [Xe] 4f⁶ 6s²

Noble gas electron configuration of Os (Osmium) = [Xe] 4f¹⁴5d⁶6s²

Noble gas electron configuration of Ba (Barium) = [Xe] 6s²

Noble gas electron configuration of Bi (Bismuth) = [Xe] 4f¹⁴5d¹⁰6s²6p³

A completely filled s, p, d, and f orbitals have 2, 6, 10 and 14 electrons respectively. Half filled s, p, d, and f orbitals have 1, 3, 5 and 7 electrons respectively.  Bi and Os have completely filled f orbitals. Sm has partially filled f orbital.

Answer: 1. 3.23 m

2. 32.4

3. B  adding solvent  and C  removing solute

Explanation:

1. Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent

Molality=\frac{n}{W_s}

where,

n = moles of solute

W_s = weight of solvent

Now put all the given values in the formula of molality, we get

Molality=\frac{43.6mol}{13.5kg}=3.23mol/kg

2. Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

3.4=\frac{n}{9.54}

n=32.4

Therefore, the moles of Na_2CO_3 is 32.4

3. Molarity can be decreased by decreasing the moles of solute and by increasing the volume of solution.

Thus adding solvent  and removing solute will decrease the molarity.

A box contains identical balls of which 12 are red, 18 white and 8 blue. Three balls are drawn from the box one after the other
svet-max [94.6K]

Answer:

a) 12/323

b) 8/233

Explanation:

a) The probability of a red ball being drawn is 12/38, or in a simplified fraction, 6/19. To find the probability that 3 are red you would multiply the probability of the fraction for each, except subtracting one from the total each time as the drawn is done without replacement. This is done as follows: 6/19 × 6/18 × 6/17= 12/323

b) The probability of drawing a blue ball is 8/38, or 4/19. To find that the first one is blue and the rest are red, the equation is done as follows: 4/19 × 6/18 × 6/17 = 8/233

(hopefully I did this right)
