Question

1,Al + HNO₃ =>Al ( NO₃)₃+NH₄NO₃+H₂O

2,HNO₂+H₂S+NO+S+H₂O

3,Cl₂+KOH=>KCl+KClO +H₂O

4,K₂C₂O₇+HCl=>KCl+CrCl₃+Cl₂+H₂O

Al+HNO₃=>Al(NO₃)₂+NO+NO₂+H₂O

Answer 1

1, 8Al + 30HNO3 = 8Al(NO3)3 + 3NH4NO3 + 9H2O 2, 2HNO2 + H2S = 2NO + S + 2H2O 3, Cl2 + 2KOH = KCl + KClO + H2O 4, K2Cr2O7 + 14HCl = 2KCl + 2CrCl3 + 3Cl2 + 7H2O 5, Bạn xem lại pt sai r

Answer 2

8Al + 30HNO₃ \(\rightarrow\) 8Al(NO₃)₃ + 3NH₄NO₃ + 9H₂O

2HNO₂ + H₂S \(\rightarrow\) 2NO + S + 2H₂O

Cl₂ + 2KOH \(\rightarrow\) KCl + KClO + H₂O

K₂Cr₂O₇ + 14HCl \(\rightarrow\) 2KCl + 2CrCl₃ + 3Cl₂ + 7H₂O

Al + 6HNO₃ \(\rightarrow\) Al(NO₃)₃ + 3NO₂ + 3H₂O
