Nh4no3, whose heat of solution is 25.7 kj/mol, is one substance that can be used in cold pack. if the goal is to decrease the temperature from 25.0 °c to 5.0 °c, how many grams of nh4no3 should we use for every 100.0 g of water in the cold pack? assume no heat was lost outside of cold pack, and the specific heat of the resulted solution was the same as water, or 4.184 j/(g•°c).

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
