Answer 2

Reaction 1: Na2O + H2O → NaOH

The reaction between sodium oxide (Na2O) and water (H2O) produces sodium hydroxide (NaOH) as the product. This is a type of reaction known as a base-oxide reaction or a base-water reaction. Sodium oxide is a basic oxide, and when it reacts with water, it forms a strong base, sodium hydroxide. The balanced chemical equation for this reaction is:

2 Na2O + 2 H2O → 4 NaOH

Reaction 2: Fe + HCl → FeCl2 + H2

The reaction between iron (Fe) and hydrochloric acid (HCl) produces iron(II) chloride (FeCl2) and hydrogen gas (H2) as the products. This is a type of reaction known as a single displacement reaction or a redox reaction. Iron displaces hydrogen from hydrochloric acid to form iron(II) chloride and hydrogen gas. The balanced chemical equation for this reaction is:

Fe + 2 HCl → FeCl2 + H2

Reaction 3: KOH + H2SO4 → K2SO4 + H2O

The reaction between potassium hydroxide (KOH) and sulfuric acid (H2SO4) produces potassium sulfate (K2SO4) and water (H2O) as the products. This is a type of reaction known as a neutralization reaction. Potassium hydroxide, a strong base, reacts with sulfuric acid, a strong acid, to form potassium sulfate and water. The balanced chemical equation for this reaction is:

2 KOH + H2SO4 → K2SO4 + 2 H2O

Reaction 4: CaO + HNO3 → Ca(NO3)2 + H2O

The reaction between calcium oxide (CaO) and nitric acid (HNO3) produces calcium nitrate (Ca(NO3)2) and water (H2O) as the products. This is a type of reaction known as an acid-base reaction or a neutralization reaction. Calcium oxide, a basic oxide, reacts with nitric acid, an acid, to form calcium nitrate and water. The balanced chemical equation for this reaction is:

CaO + 2 HNO3 → Ca(NO3)2 + H2O

Reaction 5: KClO3 → KCl + O2

The reaction of potassium chlorate (KClO3) decomposes to form potassium chloride (KCl) and oxygen gas (O2) as the products. This is a type of reaction known as a decomposition reaction. Potassium chlorate breaks down into potassium chloride and oxygen gas when heated. The balanced chemical equation for this reaction is:

2 KClO3 → 2 KCl + 3 O2

Reaction 6: P2O5 + H2O → H3PO4

The reaction between diphosphorus pentoxide (P2O5) and water (H2O) produces phosphoric acid (H3PO4) as the product. This is a type of reaction known as a hydration reaction. Diphosphorus pentoxide reacts with water to form phosphoric acid. The balanced chemical equation for this reaction is:

P2O5 + 3 H2O → 2 H3PO4
