SECTION A: ANSWER TWO(2) QUESTIONS ONLY

(1)
(i) To provide essential services: Public corporations are created to supply important services like water, electricity, transport, and postal services which private individuals may not want to provide. These services are necessary for daily living and national development.

(ii) To avoid exploitation: The government sets them up to prevent private companies from charging very high prices for important services needed by the public. This ensures that citizens can afford basic amenities.

(iii) To ensure even development: Public corporations help to provide services to both urban and rural areas, so that development is spread across the country. This reduces inequality between different parts of the nation.

(iv) To control key sectors of the economy: They allow the government to supervise important industries like power, oil, and communication, ensuring they work in the interest of the nation. This control helps to maintain stability in the economy.

(v) To create employment: Public corporations employ many people, helping to reduce unemployment in the country. This improves the standard of living for many families.

(vi) To generate revenue: Some public corporations make money from their operations, which helps the government to get additional income. This revenue can be used for development projects and public welfare.

An unwritten constitution is a constitution that is not contained in a single formal document but is based on customs, conventions, court decisions, and historical practices. It is therefore not codified in one book but scattered across many sources.

(2b)
(i) Lack of clarity: An unwritten constitution creates ambiguity in legal interpretation since rules are scattered across multiple sources. This often l

*NECO GCE 2025 CHEMISTRY ANSWERS (ESSAY)*

_INSTRUCTION: ANSWER FOUR(4) QUESTIONS ONLY_

(1ai)
Activation energy is the minimum energy required to activate atoms or molecules for a chemical reaction to occur.

(1aii)
The balanced chemical equation for the reaction is:
Zn(s) + H₂SO₄(aq) -> ZnSO₄(aq) + H₂(g)

(1aiii)
Convert temperature to kelvin = 100 + 273.15= 373.15K
Entropy change = 318.2 J K⁻¹ mol⁻¹
ΔH = T × ΔS
∆H = 373 × 318.2
= 118,736.33J mol⁻¹

Convert to kJ mol⁻¹;
∆H = 118.74 kJ mol⁻¹

(1bi)
(i) Magnetic separation: use a magnet to remove the iron filings.
(ii) Sublimation: gently heat the mixture; iodine sublimes leaving iron behind.

(1bii)
A physical change alters only physical properties like shape without forming new substances, while a chemical change forms new substances with altered composition.

(1biii)
I. Physical changes: melting of ice; dissolving sugar in water.
II. Chemical changes: rusting of iron; combustion of methane.

(1ci)
The periodic law states that the properties of elements are periodic functions of their atomic numbers.

(1cii)
Molar mass of Mg(NO₃)₂ = 24 + 2(14) + 6(16) = 148gmol⁻¹
Mass of nitrogen = 2 × 14 = 28g

% N = (28/148) × 100 = 18.92%

(1ciii)
(i) Calcium chloride (CaCl₂)
(ii) Calcium oxide (quicklime, CaO)

(1civ)
(i) Phenolphthalein
(ii) Methyl orange
===========================

(2ai)
Nitrogen is chemically inert due to its strong triple covalent bond in N₂ molecules.

(2aii)
(i) Used in the manufacture of ammonia for fertilizers via the Haber process.
(ii) Employed as an inert atmosphere to prevent oxidation in food preservation and welding.

(2aiii)
Butan-1-ol

(2aiv)
(i) Amino group (-NH₂).
(ii) Carboxyl group (-COOH).

(2bi)
A standard solution is a solution of accurately known concentration used in titrations for quantitative analysis.

(2bii)
(i) Rinse burette with the solution to be used before filling.
(ii) Read the meniscus at eye level against a white background to avoid parallax error.
(iii) Ensure n
