Question

P+S=P2S3 CuO+Al= Al2O3+Cu HCl+CaCO3= CaCL2+H2O+CO2 KClO3=KCl+O2

Answer 1

Объяснение:

2P + 3S = P2S3

3CuO + 2Al = Al2O3 + 3Cu

2HCl + CaCO3 = CaCL2 + H2O + CO2↑

2KClO3 = 2KCl + 3O2↑

Answer 2

The chemical equations you provided are balanced chemical equations, representing various chemical reactions. Here's an explanation of each equation:

1. P + S = P2S3: This equation represents the reaction between phosphorus (P) and sulfur (S) to form diphosphorus trisulfide (P2S3). The equation is already balanced.

2. CuO + Al = Al2O3 + Cu: This equation represents the reaction between copper(II) oxide (CuO) and aluminum (Al) to form aluminum oxide (Al2O3) and copper (Cu). The equation is already balanced.

3. HCl + CaCO3 = CaCl2 + H2O + CO2: This equation represents the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) to form calcium chloride (CaCl2), water (H2O), and carbon dioxide (CO2). The equation is already balanced.

4. KClO3 = KCl + O2: This equation represents the decomposition of potassium chlorate (KClO3) into potassium chloride (KCl) and oxygen gas (O2). The equation is already balanced.

These equations demonstrate different types of chemical reactions, including synthesis, decomposition, and displacement reactions.
