Question

NaOH+ZnBr2= Na3PO4+HgCl= Ba(OH)2+HNO3= K2SiO3+H2SO4= Na2S+AgCl= Cr(NO3)3+NaOH= Срочно!!!!

Answer 1

Ответ:

2NaOhZBr

7NaPOHgCl

5BanH

5KSiO+6HSO

2NaSCl

6CrNOaOh

Answer 2

NaOH + ZnBr2 = NaBr + Zn(OH)2 (double replacement reaction)

Na3PO4 + HgCl = Hg3(PO4)2 + 3NaCl (double replacement reaction)

Ba(OH)2 + HNO3 = Ba(NO3)2 + 2H2O (double replacement reaction)

K2SiO3 + H2SO4 = K2SO4 + H4SiO4 (double replacement reaction)

Na2S + AgCl = 2NaCl + Ag2S (double replacement reaction)

Cr(NO3)3 + NaOH = Cr(OH)3 + 3NaNO3 (double replacement reaction)
