Question

Va rog frumos ajutati-ma!!!
Completeaza ecuatiile reactiilor:
a)Al+?-->Al2S3
b)Al+?-->AlCl3
c)*Al+N2-->?
d)*Al+?-->Al4Cl3
e)Al+Ng(NO3)2-->?+?
f)Al+?-->Al(OH)3|+?
g)Al+HCl-->AlCl3+?
*h)Al+NaOh+H2O-->NaAlO2+?

Answer 1

a) A2l + 3S = Al2S3

b) 2Al + 3Cl2 = 2AlCl3

c) 2Al + N2 = 2AlN

d)  4Al + 3Cl = Al4Cl3

e) 2Al + 3Hg(NO3)2 = 2Al(NO3)3 + 3Hg

f)  2Al + 6H2O =2Al(OH)2 + 3H2

g) 2Al + 6HCl =2AlCl3 +3H2

h)  2Al + 2NaOH + 2H2O = 2NaAlO2 + 3H2

Answer 2

2Al +3 S=Al2S3

2Al +3 Cl2 =2AlCl3

2Al + N2=2AlN

4Al +3 C =Al4 C3                      [ aici este C  nu  Cl]

2Al +3Hg(NO3)2 =2Al ( NO3)3 +3 Hg

2Al +6H20=2Al ( OH )3 + 3H2

2Al +6HCl =2AlCl3 +3 H2

2Al +2NaOH +6H2O=2Na [Al (OH)4] +3H2
