Answer 1

[kudo shinichi]

a) 2Na + 2H₂O -> 2NaOH + H₂

b)2C_xH_y + (2x + y)O₂ -> 2xCO₂ + yH₂O

c) MnO₂ + 4HCl -> MnCl₂ + Cl₂ + 2H₂O

d) N₂O₅ + H₂O -> 2HNO₃

e) 2KMnO₄ + 16HCl -> 2KCl + 2MnCl₂ + 5Cl₂ + 8H₂O

Answer 2

[Buddy]

a) 2Na + 2H2O --> 2NaOH + H2

b)2CxHy + (2x + y)O2 ---> 2xCO2 + yH2O

c) MnO2 + 4HCl-- -> MnCl2 + Cl2 + 2H2O

d) N2O5 + H2O-- -> 2HNO3

e) 2KMnO4 + 16HCl----> 2KCl + 2MnCl2 + 5Cl2 + 8H2O
