Answer 2

Here are the balanced chemical equations for the reactions you've listed:

1. HCl + KOH → H2O + KCl This is a neutralization reaction where an acid (HCl) reacts with a base (KOH) to produce water (H2O) and a salt (KCl).

2. H2SO4 + Cr(OH)3 → Cr2(SO4)3 + 3H2O This is a double displacement reaction where sulfuric acid (H2SO4) reacts with chromium(III) hydroxide (Cr(OH)3) to produce chromium(III) sulfate (Cr2(SO4)3) and water (H2O).

3. SiO2 + 2NaOH → Na2SiO3 + H2O This is a reaction where silicon dioxide (SiO2) reacts with sodium hydroxide (NaOH) to produce sodium silicate (Na2SiO3) and water (H2O).

4. SO2 + 2LiOH → Li2SO3 + H2O This is a reaction where sulfur dioxide (SO2) reacts with lithium hydroxide (LiOH) to produce lithium sulfite (Li2SO3) and water (H2O).

5. Mg(OH)2 → MgO + H2O This is a decomposition reaction where magnesium hydroxide (Mg(OH)2) breaks down into magnesium oxide (MgO) and water (H2O).

6. FeCl2 + 2KOH → Fe(OH)2 + 2KCl This is a double displacement reaction where ferrous chloride (FeCl2) reacts with potassium hydroxide (KOH) to produce ferrous hydroxide (Fe(OH)2) and potassium chloride (KCl).
