VA ROG URGENT dau coroana si 20 de puncte URGENT si va rog rezolvati o corect... :*



Răspuns :

CaO + H2O = Ca(OH)2 

MCaO=56g/mol

MCa(OH)2=74g/mol

MH2O=18g/mol


56g CaO.................18g H2O
xg,,,,,,,,,,,,,,,,,,,,,,,,,,,900g H2O

x=900*56/18=Calculeaza!!

18gH2O.....................74g Ca(OH)2
900g H2O...................xg

x=74*900/18=Calculeaza!!!
