Explicación:
•Al2O3 + H2SO4=Al2(SO4)3 + H2O
Al2O3+3H2SO4=Al2(SO4)3+3H2O
•NaOH + CuCl2=Cu(OH)2 + NaCl
2NaOH+CuCl2=Cu(OH)2+2NaCl
•Cu + HNO3 = Cu(NO3)2 + H2O +NO2
Cu+4HNO3=Cu(NO3)2+2H2O+2NO2
•Al + H2SO4 = Al2(SO4)3 + H2
2Al+3H2SO4=Al2(SO4)3+3H2
•Cu + HNO3 = Cu(NO3)2 + H2O +NO
3Cu+8HNO3=3Cu(NO3)2+4H2O+2NO
Espero que te sirva....;)
