The Lewis structure of an oxygen atom should have Choose... dots drawn around the symbol O. The Lewis structure of a calcium atom should have Choose... dots drawn around the symbol Ca. The Lewis structure of a nitrogen atom should have Choose... dots drawn around the symbol N. The Lewis structure of an aluminum atom should have Choose... dots drawn around the symbol Al. The Lewis structure of a fluorine atom should have Choose... dots drawn around the symbol F.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
