1. Air suspension is used in cars to provide adjustability of ride height without taking your car into the shop. It works using air pumped into a cylinder under each wheel. A
2017 WRX sits 4.9 inches off the ground. In order to maintain this height, under each
wheel is a cylinder with a radius of 1.5 inches filled to a volume of 1.80L at 55psi. In
I
order to lower the ride height by 2 inches, what would the new pressure in each cylinder
need to be?

The real answer is keeping the world healthy so we won’t die

Answer: 1s²  2s²  2p⁶explanation: from the periodic table, we can note that the neutral fluorine  has 9 electrons (symbol is shown in the attached image)therefore, the configuration of neutral fluorine  is: 1s²  2s²  2p⁵now, f⁻  means that the neutral fluorine  gained one extra electron. this means that f⁻  has 10 electrons.the extra electron will occupy the 2p level to make it complete.the configuration now  is: 1s²  2s²  2p⁶comparing between both f and f⁻, we can note that f⁻  has now complete orbitals which means that it is more stable than f based on lewis postulatehope this : )
