If the pressure of a 2. 00 L sample of gas is 50. 0 kPa, what pressure does the gas exert if its volume is decreased to 20. 0 mL

N76 [4]

The equation used for the calculation is P subscript 1 V subscript 1 equals P subscript 2 V subscript 2. Thus, option B is correct.

The pressure of the gas with respect to volume is given with inverse proportion. The ideal gas equation is given as:

$PV=nRT$

<h3>Equation for relation between volume and pressure</h3>

The initial pressure of the gas has been given as, $P_1=50\;\rm kPa$

The initial volume of the gas has been, $V_1=2\;\rm L$

The final volume of the gas has been, $V_2=0.02\;\rm L$

The final pressure of the gas, $P_2$ is given as:

$P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}$

Thus, the equation used for the calculation is P subscript 1 V subscript 1 equals P subscript 2 V subscript 2. Thus, option B is correct.

D 14 3<br> N<br> 7<br> What is the number of protons, neutrons, and electrons?

Ann [662]

Answer:

Explanation:

For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146).

When two atoms collide, what determines whether they will react by transferring electrons or by sharing electrons?

Ivanshal [37]

If it is an ionic bond (metal with nonmetal) the electrons will be transferred. If it is a covalent bond (nonmetal with nonmetal) the electrons will be shared. It depends on the electronegativities; the closer the electronegativities of the two atoms, the more covalent the bond is, making the electrons more equally shared. But if the electronegativities are very different, one atom (the nonmetal) will pull the electrons from the other (the metal).

Which represents the balanced nuclear equation for the beta plus decay of C-11?

Nookie1986 [14]

Answer:

Superscript 11 subscript 6 upper C right arrow superscript 11 subscript 5 upper B plus superscript 0 subscript plus 1 e.

Explanation:

Beta decay:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle. In beta positive decay proton is converted into neutron and positron, thus the atomic number is decreased by one.

¹¹₆C → ¹¹₅B + ⁰₊₁e

In beta minus decay the one electron is ejected and neutron is converted into proton.

¹⁴₆C → ¹⁴₇N + ⁰₋₁e

Properties of beta radiations:

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation .
