Use the van der Waals equation to calculate the pressure exerted by 1.475 molmol of Cl2Cl2 in a volume of 4.635 LL at a temperature of 299.0 KK .

Answers

Answer 1

Answer:

7.812atm

Explanation:

Using Van der Waals equation, which goes as follows:

Pv = nRT

Where;

P is the pressure

V is the volume (4.635L)

n is the number of moles (1.475mol)

T is the temperature (299K)

R is the universal gas constant (0.082057 L atm mol-1K-1)

Pv = nRT

P = nRT/V

P = 1.475 × 0.0821 × 299/4.635

P = 36.2081/4.635

P = 7.812atm

Calculate the frequency of a wave with a wavelength of 5.62 x 1010 m. (first convert m to nm)

Answers

Answer:

f = 0.534×10⁻² Hz

Explanation:

Given data:

Frequency of wave= ?

Wavelength of wave = 5.62×10¹⁰ m

Solution:

Formula:

Speed of wave = wavelength × frequency

Speed of wave = 3×10¹⁷ nm/s

λ  = 5.62×10¹⁰m×10⁹  nm/1 m = 5.62×10¹⁹ nm

Now we will put the values in formula.

3×10¹⁷ nm/s = 5.62×10¹⁹ nm ×  f

f = 3×10¹⁷ nm/s  / 5.62×10¹⁹ nm

f = 0.534×10⁻² s⁻¹   or

f = 0.534×10⁻² Hz

What is the specific rotation of a sample of carvone that is an equal mixture of the R and S enantiomers

Answers

Answer:

Zero

Explanation:

An an equal mixture of the R and S enantiomers of carvone is called a racemic mixture.

In a racemic mixture, the R enantiomer rotates plane polarized light in one direction while the S enantiomer rotates plane polarized light in another direction.

This cancels out the rotation due to each enantiomer since they are equal in magnitude but opposite in direction leading to a specific rotation of zero for the racemic mixture.

The atomic masses of 20Ne (90.48 percent), 21Ne (0.27 percent), and 22Ne (9.25 percent) are 19.9924356, 20.9938428, and 21.9913831 amu, respectively. Calculate the average atomic mass of neon. The percentages in parentheses denote the relative abundance

Answers

Answer:

20.180042 amu

Explanation:

From the question given above, the following data were obtained:

Isotope A (20Ne)

Mass of A = 19.9924356 amu

Abundance (A%) = 90.48%

Isotope B (21Ne):

Mass of B = 20.9938428 amu

Abundance (B%) = 0.27%

Isotope C (22Ne):

Mass of C = 21.9913831 amu

Abundance (C%) = 9.25%

Average atomic mass of Neon =.?

The average atomic mass of Neon can be obtained as follow:

Average atomic mass = [(mass of A × A%)/100] + [(mass of B × B%)/100] + [(mass of C × C%)/100]

= [(19.9924356 × 90.48)/100] + [(20.9938428 × 0.27) /100] + [(21.9913831 × 9.25) /100]

= 18.0891557 + 0.05668338 + 2.03420294

= 20.180042 amu

Therefore, the average atomic mass of Neon is 20.180042 amu

A 7.28 g sample of chromium metal was heated to produce chromium oxide. The weight of the compound was 10.63 g. What is the percent chromium in this compound?

Answers

Answer:

68.48%

Explanation:

The percent mass of an element in a compound tells us about the amount of such element contributed to the total compound.

In this case, 7.28 g sample of chromium metal was heated to produce chromium oxide with weight of 10.63 g. The percent mass of chromium in chromium oxide can be calculated by using the formula:

%mass of Cr = mass of Cr/mass of Chromium oxide × 100%

%mass of Cr = 7.28/10.63 × 100

%mass of Cr = 0.6848 × 100

%mass of Cr = 68.48%

How many moles of H2SO4 are required to completely react with 7.20 mol of Al according to the balanced chemical reaction: 2Al(s) +3H2SO4(aq) → Al2(SO4)3(aq) +3H2(g)​

Answers

10.8

7.2mol*3/2=10.8mol.

10.8 moles of H₂SO₄ is required for the reaction.

The balanced equation for the reaction is given below:

2Al + 3H₂SO₄ —> Al₂(SO₄)₃ + 3H₂

From the balanced equation above,

2 moles of Al required 3 moles of H₂SO₄.

Finally, we shall determine the number of mole of H₂SO₄ required to react with 7.20 moles of Al.

This can be obtained as follow:

From the balanced equation above,

2 moles of Al required 3 moles of H₂SO₄.

Therefore,

7.20 moles of Al will require = [tex]\frac{7.2 X 3}{2} \\\\[/tex] = 10.8 moles of H₂SO₄

Thus, 10.8 moles of H₂SO₄ is required for the reaction.

D)

Answers

Answer:

B) . six electrons in the triple bond of diatomic nitrogen

Explanation:

The three line in this Lewis dot structure represents the six electrons in the triple bond of diatomic nitrogen.

Nitrogen is made up of 7 electrons with 5 valence ones.

 A lewis structure is made up of the symbol of the element surrounded by dot to represent the valence electrons.

  In this nitrogen molecule, both species share  6 electrons. This makes each nitrogen atom isoelectronic with neon.
