Question

P + O2 = P2 O5 Fe + Cl2 = FeCl3 Zn + HCl = ZnCl2 + H2 HgO == Hg + O2 Mg + O2 = MgO Ag2O= Ag+ O2 Al + S= Al2S3 Ca+ HCl= CaCl2 + H2 Al + S = Al2S3 Zn + HCl = ZnCl2 + H2 Au2O3 = Au + O2 P2O5 + H2O = H3PO4

Answer 1

2Fe + 3Cl2 = 2FeCl3
Zn + 2HCl = ZnCl2 + H2
2HgO = 2Hg + O2
2Mg + O2 = 2MgO
2Ag2O= 4Ag+ O2
2Al + 3S= Al2S3
Ca+ 2HCl= CaCl2 + H2
2Al + 3S = Al2S3
Zn + 2HCl = ZnCl2 + H2
2Au2O3 = 4Au + 3O2
P2O5 + 3H2O = 2H3PO4
4P + 2O5 = 2P2O5

Answer 2

The given equation represents a series of chemical reactions. Let's break it down step by step:

1. P + O2 = P2O5: - Phosphorus (P) reacts with oxygen (O2) to form diphosphorus pentoxide (P2O5) [[1]].

2. Fe + Cl2 = FeCl3: - Iron (Fe) reacts with chlorine (Cl2) to form iron(III) chloride (FeCl3) [[2]].

3. Zn + HCl = ZnCl2 + H2: - Zinc (Zn) reacts with hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2) [[3]].

4. HgO = Hg + O2: - Mercury(II) oxide (HgO) decomposes into mercury (Hg) and oxygen gas (O2) [[4]].

5. Mg + O2 = MgO: - Magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO) [[5]].

6. Ag2O = Ag + O2: - Silver(I) oxide (Ag2O) decomposes into silver (Ag) and oxygen gas (O2) [[6]].

7. Al + S = Al2S3: - Aluminum (Al) reacts with sulfur (S) to form aluminum sulfide (Al2S3) [[7]].

8. Ca + HCl = CaCl2 + H2: - Calcium (Ca) reacts with hydrochloric acid (HCl) to form calcium chloride (CaCl2) and hydrogen gas (H2) [[8]].

9. Al + S = Al2S3: - Aluminum (Al) reacts with sulfur (S) to form aluminum sulfide (Al2S3) [[7]].

10. Zn + HCl = ZnCl2 + H2: - Zinc (Zn) reacts with hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2) [[3]].

11. Au2O3 = Au + O2: - Gold(III) oxide (Au2O3) decomposes into gold (Au) and oxygen gas (O2) [[9]].

12. P2O5 + H2O = H3PO4: - Diphosphorus pentoxide (P2O5) reacts with water (H2O) to form phosphoric acid (H3PO4) [[10]].
