Answer 1

Объяснение:

1. 2K+S→. K2S

3. K+O2→ KO2 (надпероксид калия)

5. 2K+ 2HCl→ 2KCl + H2↑

2.Mg+ Cl2→ MgCl2

4. 2Mg+ O2→ 2MgO

6. Mg+ H2 SO4 → MgSO4 + H2↑

Answer 2

1. K + S -> K2S This equation represents the reaction between potassium (K) and sulfur (S) to form potassium sulfide (K2S). One atom of potassium reacts with one atom of sulfur to produce one molecule of potassium sulfide.

2. K + O2 -> KO2 This equation represents the reaction between potassium (K) and oxygen (O2) to form potassium superoxide (KO2). One atom of potassium reacts with one molecule of oxygen to produce one molecule of potassium superoxide.

3. K + HCl -> KCl + H2 This equation represents the reaction between potassium (K) and hydrochloric acid (HCl) to form potassium chloride (KCl) and hydrogen gas (H2). One atom of potassium reacts with one molecule of hydrochloric acid to produce one molecule of potassium chloride and one molecule of hydrogen gas.

4. Mg + Cl2 -> MgCl2 This equation represents the reaction between magnesium (Mg) and chlorine (Cl2) to form magnesium chloride (MgCl2). One atom of magnesium reacts with one molecule of chlorine to produce one molecule of magnesium chloride.

5. Mg + O2 -> MgO This equation represents the reaction between magnesium (Mg) and oxygen (O2) to form magnesium oxide (MgO). One atom of magnesium reacts with one molecule of oxygen to produce one molecule of magnesium oxide.

6. Mg + H2SO4 -> MgSO4 + H2 This equation represents the reaction between magnesium (Mg) and sulfuric acid (H2SO4) to form magnesium sulfate (MgSO4) and hydrogen gas (H2). One atom of magnesium reacts with one molecule of sulfuric acid to produce one molecule of magnesium sulfate and one molecule of hydrogen gas.
