Question

Se cere finisati ecuatia reactiilor si egaleazale a)H2+O2_>t° b)CH4+O2_>t°?+? c)CaCO3_>t°CaO+? d)P+?_>t°P2O5 e)Al(OH)3_>t°?+? f)?+O2_>t°SO2In care dintre aceste reactii se formeaza concomitent oxizi acizi si oxizii bazici

Answer 1

a)2H2+O2=2H2O(caracter amfoter).
b)CH4+2O2=CO2(caracter acid)+2H2O
c)CaCO3=CaO(caracter bazic)
+CO2(caracter acid )-aici se formeaza oxid bazic si oxid acid
d)P4+5O2=2P2O5(caracter acid)
e)2Al(OH)3=Al2O3(caracter bazic)+3H2O
f)S+O2=SO2(caracter acid)
