Please provide short answers as to what they should do or why they have these observations. a) 'I think my separatory funnel is broken. I opened the stopcock to drain the layers and nothing happened.' b) 'I added a second volume of ether to the separatory funnel for my second extraction, but I see only one layer.' c) 'I forgot which layer is ether and which is H2O.' or 'I can't figure out which layer is aqueous.'

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

the answer is either b or c

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
