molecular orbital theory correctly predicts paramagnetism according to mo theory, overlap of two p atomic orbitals produces .oxy
Mkey [24]

Overlap of two p atomic orbital produces oxygen gas ,o2 because it has two unpaired electron and explains paramagnetism.

O2 molecules have two unpaired electrons Materials in which all the electrons are paired are diamagnetic. It repel a magnetic field.Para magnetic and diamagnetic materials do not act as permanent magnets. Molecular orbital theory provides an explanation  of chemical bond that explains paramagnetism of the oxygen molecule. It also explains the bonding in a other molecule. O2 molecule has two unpaired electron.  Electrons creates magnetic field as it goes to the ground state and also spin.MO theory describes the distribution of electrons in molecules same as the distribution of electrons in atoms described using atomic orbital.

1.00 L of a gas at STP is compressed to 473mL. What is the new pressure of gas?
Ratling [72]

Hello!

1.00 L of a gas at STP is compressed to 473 mL. What is the new pressure of gas?

  • <u><em>We have the following data:</em></u>

Vo (initial volume) = 1.00 L  

V (final volume) = 473 mL → 0.473 L  

Po (initial pressure) = 1 atm (pressure exerted by the atmosphere - in STP)  

P (final pressure) = ? (in atm)

  • <u><em>We have an isothermal transformation, that is, its temperature remains constant, if the volume of the gas in the container decreases, so its pressure increases. Applying the data to the equation Boyle-Mariotte, we have:</em></u>

P_0*V_0 = P*V

1*1 = P*0.473

1 = 0.473\:P

0.473\:P = 1

P = \dfrac{1}{0.473}

\boxed{\boxed{P \approx 2.11\:atm}}\:\:\:\:\:\:\bf\green{\checkmark}

<u><em>Answer:  </em></u>

<u><em>The new pressure of the gas is 2.11 atm  </em></u>

The water pressure on Mustafa as he dives is increasing at a rate of 0.9920.9920, point, 992 atmospheres (\text{atm})(atm)left p
pantera1 [17]

Based on the given scenario, the rate of increase in water pressure in atm/km is known to be 992 atm/km.

<h3>What is water pressure?</h3>

Pressure is known to be that kind of force that is known to often pushes water via pipes.

Note that Water pressure is a tool that is often used to know or identify the flow of water from any given tap. The amount of pressure at one's tap is said to be often dependent on how high the service tank or water tower is above one's home.

Therefore since 1 atm/m  = 1000 atm/km

Hence 0.992 atm/m  :

           = 0.992 x 1000

          = 992 atm/km.

Therefore, Based on the given scenario, the rate of increase in water pressure in atm/km is known to be 992 atm/km.
