Complete the sentences to explain what a similar treatment would predict for the effective nuclear charge on boron valence elect

dsp73

Answer:

ZcH's electrons = 5-2 = +3.

ZcH for inner electrons = -5 - 0 = +5.

Explanation:

Boron 1s² 2s² 2p

As, 2s ⇒ 2.58.

2p ⇒ 2.42.

Electrons = +3.

Greater than 2 cm = 0.35

Slightly greater than +3 .

If I have one mole of sulfur, how many atoms would that be?

krok68 [10]

Answer:

Atoms of sulfur = 9.60⋅g32.06⋅g⋅mol−1×6.022×1023⋅mol−1

Explanation:

because the units all cancel out, the answer is clearly a number, ≅2×1023 as required.

The volume of air in a person’s lungs is 615 mL at a pressure of 760. mmHg. Inhalation occurs as the pressure in the lungs drops

chubhunter [2.5K]

<u>Answer:</u> The final volume of lungs is 621.5 mL

<u>Explanation:</u>

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

$P_1V_1=P_2V_2$

where,

$P_1\text{ and }V_1$ are initial pressure and volume.

$P_2\text{ and }V_2$ are final pressure and volume.

We are given:

$P_1=760mmHg\\V_1=615mL\\P_2=752mmHg\\V_2=?mL$

Putting values in above equation, we get:

$760mmHg\times 615mL=752mmHg\times V_2\\\\V_2=\frac{760\times 615}{752}=621.5mL$

Hence, the final volume of lungs is 621.5 mL
