Question

Am nevoie de ajutor!Se da sirul transformărilor:
NaCl-->Na+g
Na+a-->b+H2
b+CO2-->c+a
b+ H2SO4-->d+a
b+ CuSO4-->d+ f
g+H2-->h
h+ Mg-->j+H2
Identificati Substanțele corespunzătoare literelor!dau coronita pt raspuns corect✋

Answer 1

2Na---->2Na+Cl2(g)
2Na+2H2O(a)--> 2NaOH(b)+H2
2NaOH+CO2--> Na2CO3(c)+H2O(a)
2NaOH+H2SO4-->Na2SO4(d)+H2O
2NaOH+CuSO4--> Na2SO4+Cu(OH)2(f)
Cl2+H2--> 2HCl(h)
2HCl+Mg--> MgCl2(j)+H2
