A sample of gas at 15 Cati atm) has a volume of 2.58 L. The temperature is then raised to 38°C (at 1 atm)
a. Does the volume of the gas increase or decrease?
b. Calculate the new volume,

I'm sorry i cant you if you don't list the elements : (

The answer is b. because when it leaves the bat, its bringing motion on where its going.

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 : )
