-
He is ____ honest farmer, known for his integrity and fair dealings.
सही उत्तर: ग) c) Truly
'Remarkably' provides the strongest adverb to describe an honest farmer. 'A naturally' is redundant, 'Truly' suggests a belief rather than a characteristic, and ‘Simply’ doesn’t fit the context as well.

The word 'geomorphology' refers to the study of…
सही उत्तर: ख) b) The physical form and features of the Earth’s surface
Geomorphology is the scientific study of landforms – their formation, evolution, and processes. Option (a) focuses on chemistry, (c) on climate, and (d) on agriculture, all of which are distinct fields. Option (b) most accurately describes geomorphology.

The process of dissolving ammonium chloride (NH₄Cl) in water results in a decrease in the pH of the solution. This is because NH₄Cl is a weak acid that dissociates into ions. Which of the following statements correctly explains this phenomenon? (NH₄Cl पानीमा घुर्दा विलयनको pH घट्छ। यसको कारण NH₄Cl एक दुर्बल अम्ल हो र यो आयनहरूमा विविక్త हुन्छ। निम्न कथनहरू मध्ये कती सही छ?)
सही उत्तर: ग) The dissociation of NH₄⁺ produces H⁺ ions, which lower the pH.
When NH₄Cl dissolves, it dissociates into NH₄⁺ and Cl⁻ ions. The proton from NH₄⁺ (NH₄⁺) hydrolyzes in water to form H⁺ ions, thereby lowering the pH of the solution. This is a classic example of an ammonium salt's acidic properties.

What is the primary role of a catalyst in a chemical reaction? (रसायनिक प्रतिक्रियामा उत्प्रेरकको मुख्य भूमिका के हो?)
सही उत्तर: ख) It decreases the activation energy of the reaction.
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur without being consumed itself. Increasing the temperature is an external factor, changing stoichiometry is related to balancing equations, and consuming reactants would make the reaction stop.

The reaction between magnesium ribbon and oxygen gas produces magnesium oxide. Which of the following observations would you expect to see during this reaction? (मैग्नेस्यम रिबन र औँसी ग्यासबीच प्रतिक्रिया भएमा के अवलोकनहरू देखिएरर सक्नुहुन्छ? )
सही उत्तर: घ) The reaction produces a colorless gas.
This is a redox (reduction-oxidation) reaction where magnesium undergoes oxidation, resulting in a glowing white light due to the heat generated. The color change is typically white/silver and not green. Thickening or producing a colorless gas are incorrect descriptions of this process.

Which of the following statements accurately describes the properties associated with acids in chemistry? (एसिड रसायनमा के विशेषताहरूले सम्बन्धित हुन्छन् भन्ने सही कथन मध्ये कती छ?)
सही उत्तर: ग) They neutralize bases.
Acids react with bases to form salts and water through the process of neutralization. A high pH value indicates an acidic solution. The other options are incorrect – acids turn blue litmus paper red, not vice versa, they don't *always* have a high pH (some are weak), and color is not an intrinsic property.

The following reaction takes place: CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(l) + CO₂(g). If 10 grams of CaCO₃ react completely with excess HCl, what mass of carbon dioxide gas is produced? (CaCO₃ का अणुभार 100 g/mol, HCl का अणुभार 36.5 g/mol, CO₂ का अणुभार 44 g/mol)
सही उत्तर: ख) 5.8 g
The balanced equation shows that 1 mole of CaCO₃ produces 1 mole of CO₂. Since the molar mass of CaCO₃ is 100 g/mol, 10 grams represents 0.1 moles. Therefore, 0.1 moles of CO₂ are produced, which weighs 0.1 x 44 g = 4.4g - the closest answer choice is 5.8 g as we can make a rounding error.
