Which of the following gas samples would have the largest number of representative particles at STP? A. 0.520 L SO3 B. 0.10 L Xe
egoroff_w [7]

Answer: The correct option is D.

Explanation: To calculate the larges number of partivles of gas, we will use Avogadro's Law which says that volume of the gas is directly related to the number of moles of gas at constant pressure and temperature.

Mathematically,

\frac{V_1}{n_1}=\frac{V_2}{n_2}       ....(1)

The gas which has the largest number of moles, will have the largest number of particles.

We are provided to use STP conditions, which says that

1 mole of a gas occupies 22.4 L of volume.

Initial conditions:

n_1=1mole

V_1=22.4L

  • A. 0.520 L of SO_3

V_2=0.520L

Putting all the values, in equation 1, we get

\frac{22.4}{1}=\frac{0.520}{n_2}

n_2=0.0232moles

  • B. 0.10 L of Xe

V_2=0.10L

Putting all the values, in equation 1, we get

\frac{22.4}{1}=\frac{0.10}{n_2}

n_2=0.0044moles

  • C. 7.0 L of N_2

V_2=7.0L

Putting all the values, in equation 1, we get

\frac{22.4}{1}=\frac{7.0}{n_2}

n_2=0.3125moles

  • D. 12.0 L of Ne

V_2=12.0L

Putting all the values, in equation 1, we get

\frac{22.4}{1}=\frac{12.0}{n_2}

n_2=0.5357moles

Hence, from the above calculations, we see that option D has the largest amount of moles and hence, will have the largest amount of particles.

After James Chadwick discovered the neutron, atomic theory expanded to include isotopes. Isotopes have many practical uses. For
andrew-mc [135]

Answer:

The answer is C which is 8 neutrons

Explanation:

This is because all carbon isotopes have 6 protons in their nucleus. Carbon 14 have 2 extra neutron aside from only having 6. So 6 protons + 6 neutrons + 2 more extra makes 14 which makes it Carbon - 14. I hope this makes sense.
