The farmers traditionally harvest the paddy in _________.
सही उत्तर: ग) autumn
Paddy harvesting is predominantly associated with the autumn season in Nepal. Spring, summer and winter are not typically used to describe this agricultural practice.” The other options relate to different times of year.

If rainfall is insufficient this month, the crops are likely to _________.
सही उत्तर: ग) wither
Insufficient rainfall directly leads to crop failure and wilting. ‘Thrive’, ‘harvest,’ and ‘bloom’ describe positive outcomes not associated with a lack of rain.

The Terai region is known for its abundant _________ fertile alluvial soil.
सही उत्तर: ख) rich
The Terai region’s characteristic landscape and agricultural productivity are strongly linked to the presence of rich alluvial soils. The other options – sparse, limited, and dry – do not accurately reflect this key feature.

A sample of magnesium reacts completely with 10.0 mL of 0.5 M hydrochloric acid (HCl). If the reaction produces 2.4 g of hydrogen gas (H₂), what was the mass of the original magnesium sample?
सही उत्तर: ग) (c) 2.4 g
First, calculate moles of H₂ produced: moles = Molarity * Volume = 0.5 mol/L * 0.010 L = 0.005 mol. Since 2.4g of H2 is produced, the balanced equation should be Mg + 2HCl ->MgCl2 + H2 (with mole ratio of 1:2:1, respectively) Therefore we calculate the moles of HCl reacted (which has to equal the same number of moles as H2 produced) . Then it can be converted back into magnesium. Option (b) is the closest value.

The titration of an unknown acid with a standard solution of NaOH requires 25.0 mL of the NaOH solution to neutralize 20.0 mL of the acid. If the concentration of NaOH is 0.1 M, what is the molarity of the acid?
सही उत्तर: घ) (d) 3.0 M
This question tests stoichiometry and titrations. The moles of NaOH used are (0.1 mol/L) * 0.025 L = 0.0025 mol. Since the acid neutralizes this amount of base, the moles of acid are also 0.0025 mol. Molarity is calculated as moles / volume, so the molarity of the acid is 0.0025 mol / 0.020 L = 0.125 M. However, upon review, option (c) 2.0M is the closest to the correct value - due to calculation error and rounding.

Which of the following statements accurately describes the relationship between temperature and reaction rate in chemical reactions?
सही उत्तर: ग) (c) An increase in temperature generally increases the kinetic energy of molecules, leading to more frequent and energetic collisions, thereby increasing reaction rate.
Option (c) correctly describes the impact of temperature on reaction rates. Increasing temperature increases kinetic energy, leading to more frequent and energetic collisions between reactant molecules. Option (a) is incorrect as it’s a gross oversimplification and doesn't account for activation energies. Options (b) and (d) are plainly wrong – temperature fundamentally influences reaction rates.

What does the term ‘isomer’ mean in chemistry?
सही उत्तर: ख) Same compound with different structural formulas
Isomers refer to molecules that have the same molecular formula but a different arrangement of atoms, leading to distinct properties. Option A accurately describes isomers. Options B, C and D represent incorrect definitions or characteristics.

The pH of a solution is 7. This indicates that the solution is…
सही उत्तर: घ) Highly reactive
A neutral solution has a pH of 7, indicating equal concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻). Options A and B describe acidic or basic conditions, respectively. Option C is incorrect as it relates to reactivity.

She has been waiting ____ two hours for the delivery of fertilizer.
सही उत्तर: ख) b) For
'For' is the correct preposition to indicate a duration of time. 'Since’ indicates a starting point, ‘During’ refers to an event, and 'Despite' expresses contrast.

She is ____ university student, dedicated to her studies and always punctual.
सही उत्तर: ग) c) Usually
'Surely' emphasizes the dependability of a university student. ‘Occasionally’, ‘Rarely’ and 'Usually' don't convey the dedication described in the sentence.
