2problems of acid rain?
kill aquatic life
can erode buildings
what element from soil caused harm to aquatic life?
aluminium
how are nitrous oxides made in engines?
temp of engine forces nitrogen+oxygen to react
how can acid rain affect human life?
trees killed
vegetation killed
how can acid rain affect food chains in lakes?
organisms cant feed/reproduce
whats the test for hydrogen?
lit splint over test tube,if pops hydrogen is present
process of salt?
reacting metal compound with acid
test for carbon dioxide?
limewater,if goes cloudy then carbondioxide is present
effects acid has on rocks
deteriate+weather rocks away making the edges rigged
neutralisation reaction
base+acid->metal salt+water
definition of neutralisation
chemical reaction where the acid+base react with an equal quantity of eachother
