1. Zn+AgNO3= 2. Zn+Mg= 3. Zn+O2= 4. NaOH+AgNO3= 5. Mg+H2O= 6. Mg+O2=

Question

1. Zn+AgNO3=
2. Zn+Mg=
3. Zn+O2=
4. NaOH+AgNO3=
5. Mg+H2O=
6. Mg+O2=

Answer 1

Zn + 2AgNO3 = Zn(NO3)2 + 2Ag

2. Zn + Mg = реакции не будет
3. 2Zn + O2 = 2Zn0
4.NaOH + AgNO3 = NaNO3 + AgOH
5. 2Mg +2 H2O = 2Mg(OH)2
6.2Mg + O2 = 2MgO
