11. Zinc metal reacts with aqueous silver nitrate to produce solid silver and an aqueous solution of zinc nitrate.

Balanced Equation:

Answer 1

1. 2 Na + 2 H2O ---> 2 NaOH + H2
SD, if anything.
2. 2 CO + O2 ----> 2 CO2
C
3. FeS + 2 HCl ---> FeCl2 + H2S
DD
4. 2 NaNO3 ---> 2 NaNO2 + O2
D
5. CH4 + 2 O2 -----> CO2 + 2 H2O
C
6. Fe + 2 CuNO3 ---> Fe (NO3)2 + Cu
SD
7. 2 KI + Cl2 -------> 2 KCl + I2
SD
8. 2 Al + 3 S ---> Al2S3
S
9. 2 KClO3 ----> 2 KCl + 3 O2
D
10. 2 C4H10 + 18 O2 ----> 8 CO2 + 10 H2O
C
11. Zn (s) + 2 AgNO3 (aq) ----> 2 Ag (s) + Zn(NO3)2 (aq)
SD
