Make up the reaction equations according to the schemes a) Zn + O2- ZnO b) Fe + CI2-; FeCI3

Make up the reaction equations according to the schemes a) Zn + O2- ZnO b) Fe + CI2-; FeCI3 c) Ag + S- Ag2S d) Na + CI2- NaCI e) Mg + O2- MgO f) Al + CI2- AL2CI3 g) AL + S- AL2S3 h) Ca + O2- CaO

Let’s compose the reaction equations:
a) 2Zn + O2 = 2ZnO;
b) 2Fe + 3Cl2 = 2FeCl3;
c) 2Ag + S = AgS;
d) 2Na + Cl2 = 2NaCl;
e) 2Mg + O2 = 2MgO;
f) 2Al + 3Cl2 = 2AlCl3;
g) 2Al + 3S = Al2S3;
h) 2Ca + O2 = 2CaO.
Metals interact with non-metals to form salts. Non-metals – oxygen, sulfur and chlorine exhibit oxidizing properties. Metals such as zinc, iron, silver, sodium, magnesium, aluminum and calcium confirm the properties of reducing agents. The reactions are classified as oxidative – reduction.
