Explanation:
During the formation of BeCl2, the beryllium atom bonds with two chlorine atoms via single covalent bonds. The number of electron pairs around the central atom will be two. No lone pair is found in the molecule. If we analyse this information then we can conclude that BeCl2 has sp hybridization.

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](https://tex.z-dn.net/?f=P_0%2AV_0%20%3D%20P%2AV)
![1*1 = P*0.473](https://tex.z-dn.net/?f=1%2A1%20%3D%20P%2A0.473)
![1 = 0.473\:P](https://tex.z-dn.net/?f=1%20%3D%200.473%5C%3AP)
![0.473\:P = 1](https://tex.z-dn.net/?f=0.473%5C%3AP%20%3D%201)
![P = \dfrac{1}{0.473}](https://tex.z-dn.net/?f=P%20%3D%20%5Cdfrac%7B1%7D%7B0.473%7D)
![\boxed{\boxed{P \approx 2.11\:atm}}\:\:\:\:\:\:\bf\green{\checkmark}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7BP%20%5Capprox%202.11%5C%3Aatm%7D%7D%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5Cbf%5Cgreen%7B%5Ccheckmark%7D)
<u><em>Answer: </em></u>
<u><em>The new pressure of the gas is 2.11 atm </em></u>

Answer: C. Convection currents in the asthenosphere.
Explanation: Most geologists think that the movement of Earth's plates is caused by convection currents in the asthenosphere.
