Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the eq
____ [38]

Answer:

The gas is decreasing at a rate of 50 cubic centimeters per minute.

Explanation:

The Boyle's Law is represented by the following expression:

P\cdot V = k (1)

Where:

P - Pressure, in kilopascals.

V - Volume, in cubic centimeters.

k - Proportionality constant, in kilopascal-cubic centimeters.

By definitions of rate of change and implicit differentiation, we derive the following differential equation:

\dot P \cdot V + P\cdot \dot V = 0 (2)

Where:

\dot P - Rate of change of the pressure, in kilopascals per minute.

\dot V - Rate of change of the volume, in cubic centimeters per minute.

Then, we clear the rate of change of the volume within (2):

P\cdot \dot V = -\dot P\cdot V

\dot V = -\left(\frac{\dot P}{P} \right) \cdot V

If we know that P = 180\,kPa, \dot P = 30\,\frac{kPa}{min} and V = 300\,cm^{3}, then the rate of change of the volume is:

\dot V = -\left(\frac{\dot P}{P} \right) \cdot V

\dot V = -50\,\frac{cm^{3}}{min}

The gas is decreasing at a rate of 50 cubic centimeters per minute.

What is the molecular formula of a compound with the empirical formula so and molecular weight 96.13?
garik1379 [7]
<h3>Answer:</h3>

                  Molecular Formula  =  S₂O₂  (Disulfur Dioxide)

<h3>Solution:</h3>

Molecular formula is calculated by using following formula,

                    Molecular Formula  =  n × Empirical Formula  ---- (1)

Also, n is given as,

                     n  =  Molecular Weight / Empirical Formula Weight

Molecular Weight  =  96.13 g.mol⁻¹

Empirical Formula Weight  =  32.06 (S) + 16.0 (O)  =  48.06 g.mol⁻¹

So,

                     n  =  96.13 g.mol⁻¹ ÷ 48.06 g.mol⁻¹

                     n  =  2.0002 ≈ 2

Putting Empirical Formula and value of "n" in equation 1,

                    Molecular Formula  = 2 × SO

                    Molecular Formula  =  S₂O₂  (Disulfur Dioxide)

If the pressure on a 1.04 L sample of gas is doubled at constant temperature, please compute the new volume of gas: __
natulia [17]

Answer:

0.52 L.

Explanation:

Let P be the initial pressure.

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

Initial pressure (P1) = P

Initial volume (V1) = 1.04 L

Final pressure (P2) = double the initial pressure = 2P

Final volume (V2) =?

The new volume (V2) of the gas can be obtained by using the the Boyle's law equation as shown below:

P1V1 = P2V2

P × 1.04 = 2P × V2

1.04P = 2P × V2

Divide both side by 2P

V2 = 1.04P /2P

V2 = 0.52 L

Thus, the new volume of the gas is 0.52 L.
