Answer 2

Chemical Equations

Chemical equations represent the reactions between different substances. Let's break down the equations you provided and explain what each one represents.

1. Na + S = Na2S - This equation represents the reaction between sodium (Na) and sulfur (S) to form sodium sulfide (Na2S) [[1]].

2. Al2O3 + H2 = Al + H2O - This equation represents the reaction between aluminum oxide (Al2O3) and hydrogen gas (H2) to form aluminum (Al) and water (H2O) [[2]].

3. HCl = H2 + Cl2 - This equation represents the decomposition of hydrochloric acid (HCl) into hydrogen gas (H2) and chlorine gas (Cl2) [[3]].

4. C + O2 = CO2 - This equation represents the combustion reaction between carbon (C) and oxygen gas (O2) to form carbon dioxide (CO2) [[4]].

5. Ca + Al2O3 = CaO + Al - This equation represents the reaction between calcium (Ca) and aluminum oxide (Al2O3) to form calcium oxide (CaO) and aluminum (Al) [[5]].

6. HCl + Al2O3 = AlCl3 + H2O - This equation represents the reaction between hydrochloric acid (HCl) and aluminum oxide (Al2O3) to form aluminum chloride (AlCl3) and water (H2O) [[6]].
