gases like carbon dioxide,carbon monoxide,oxides of sulphur,oxides of nitrogen etc r not abundant in r atmosphere..however these react with water to form acids..like the mild carbonic acid..but the much more harmfull nitrous,nitric,sulphurous,sulphuric acids..pollution basically increases the amount of these gases in r atmsphere..thus when it rains..water chemically reacts with these gases etc to create a liquid which is mainly water but has the resulting acids in it too..thus its pH shifts below 7..acidic…hmm…thats acid rain…we can mainly reduce it by controlling pollution…especially automobile pollution which results is most of the sulphur n nitrogen oxides…carbon monoxide n dioxide also need to be kept within limits..using scrubbers is vehicles..aforestation..greener surroundings..proper disposal of waste in factories etc can form the main preventive measures..chemical equations:::

(CO,CO2)+(O2,H20)===>H2CO3

(SO2,SO3)+(O2,H20)===>H2SO3,H2SO4

(NO,NO2)+(O2,H20)===>H2NO2,H2NO3

etc etc.

Just tell him you’re a lose girl who does not want a boyfriend. Tell him that you are shallow and see guys as objects and not people, and he would be nothing more than one of your common idiotic “toys”, as you are incapable of committing to one person, because the world will end if you do. You would be being honest and giving him the heads up about someone who means him no good(you)! Or you could just try growing up and learning how to treat guys. No man deserves this. Men are people and not “toys”! How would you like to be treated this way! Two wrongs don’t make a right!

Acid rain is caused by pollutants in the air. Pollute less.
