Question

Осуществите превращение Na →NaOH→NaCl

Answer 1

2Na+H2=2NaH

2NaH+O2=2NaOH

2NaOH+H2SO4=Na2SO4+H2O

Na2SO4+2KOH=K2SO4+2NaOH

NaOH+HCl=NaCl+H2O

Na+1+OH-+H+1+Cl-=Na+1+Cl-+H+1+OH-

H+1+OH-=H2O

2NaCl+H2=2HCl+2Na

Answer 2

Объясни вот это - Na+1+OH-+H+1+Cl-=Na+1+Cl-+H+1+OH-

H+1+OH-=H2O

Answer 3

Na+OH=NaOH

NaOH+HCl+H2O

Answer 4

2Na + 2H2O = 2NaOH + H2
