Correct Answer: C. labour

Correct Answer: D. reserved capital

Explanation

A company may reserve a portion of its uncalled capital to be called only in the event of winding up of the company. Such uncalled amount is called 'Reserve Capital' of the company. It is available only for the creditors on winding up of the company.

Correct Answer: D. Temperature increases with height

Explanation

Chairman, Panel of Judges, Co-debaters, Ladies and Gentlemen, I am here to speak against the motion which states that education is not as important as riches. Education is a process of acquiring learning and knowledge which equips an individual for the challenges of life. It makes an individual to be adequately fit into the society in which he finds himself. Education as against ignorance, brings out the best in every individual. Riches, on the other hand, has to do with acquiring wealth and opulence which may be difficult to maintain without adequate knowledge.

There is a common saying that if education is expensive, try ignorance. This is true as education has to do with acquiring knowledge with which riches can be adequately administered and controlled. What is riches without education? It is useless and unworthy without education. A rich man without education will definitely discover that something i substantial and great is missing in his life. He feels the yawning gap n his life. He may have the money to throw around but he may fritter away his money if he lacks good education to administer his wealth. He may hire educated people to assist him in the company or business he establishes but the fact is that he lacks the knowledge to adequately control his enormous wealth. He has to depend on educated people around him for the successful administration of his wealth.

Apart from this, an uneducated rich person is already restricted and limited in the society. His experience is not complete if he has not attended any school as there is giving to be a yawning gap between him and those who are educated. He cannot be trusted with positions where education is a Prerequisite. He cannot aspire to become a governor of a state or the president of a country.

Education has the capacity to transform from being ignorant to being informed. Riches, no matter how enormous it is, cannot do this. It is a mind opener as it makes a person not to be narrow-minded. Education is a liberator of the mind in a way that riches deformed mind. Riches can't do this; cannot be. An informed person is already liberated and he cannot have a person to be self-assuming. s, it can only make a person to be arrogant and proud because wealth can make a person self-assuming.

Definitely, education is the most important factor in determining a successful life. Even education is essential in one's life and it could be a pathway to riches. Chairman, Panels of Judges, I hope that with these few points of mine, I have been able to convince you that education is as important as riches.

Correct Answer: C. Metals ionize by electron gain while non-metals form ions by electron loss

Explanation

Let's analyze each statement:

A. Metals high up in the redox series are usually extracted by electrolysis.

• The redox series (or reactivity series) places highly reactive metals (like K, Na, Ca, Mg, Al) at the top.

• These metals form very stable compounds and cannot be easily reduced by common reducing agents like carbon.

• Electrolysis of their molten salts (e.g., Al from Al₂O₃, Na from NaCl) is the primary method to extract them due to its strong reducing power.

• This statement is correct.

B. Lead is less reactive than magnesium therefore it is lower in the redox series.

• The redox series arranges metals in order of decreasing reactivity. More reactive metals are higher in the series.

• Magnesium (Mg) is a highly reactive Group 2 metal. Lead (Pb) is a much less reactive Group 14 metal.

• Therefore, magnesium is indeed higher in the redox series than lead, meaning lead is lower because it is less reactive.

• This statement is correct.

C. Metals ionize by electron gain while non-metals form ions by electron loss.

• Metals (e.g., Na, Mg, Al) tend to *lose* valence electrons to form positive ions (cations) to achieve a stable electron configuration. For example, Na → Na⁺ + e⁻.

• Non-metals (e.g., Cl, O, S) tend to *gain* electrons to form negative ions (anions) to achieve a stable electron configuration. For example, Cl + e⁻ → Cl⁻.

• The statement incorrectly swaps the processes: it says metals gain electrons and non-metals lose electrons.

• This statement is not correct.

D. An amphoteric oxide exhibits both acidic and basic properties.

• An amphoteric substance is one that can react as both an acid and a base.

• Amphoteric oxides (e.g., Al₂O₃, ZnO, PbO) react with acids to form salt and water (acting as a base) and react with bases to form salt and water (acting as an acid).

• This statement is correct.

Therefore, the statement that is not correct is C.

The final answer is C

Correct Answer: A. III and VI

Explanation

The major reasons some countries are termed developing resulted from Political apathy (III) and Responsible parenting (VI). Political apathy refers to the indifference towards political activities, which can hinder the development of a country. Responsible parenting, on the other hand, is crucial for the upbringing of responsible citizens who contribute to the development of the country.

Correct Answer: D) ethanoic acid
