Fill in the blank: The phrase ‘a penny saved is a penny earned’ best illustrates the importance of _____.

The average gestation period of a cow, typically a dairy breed, is approximately:
सही उत्तर: ख) 10-11 months
Dairy cows generally have a gestation period of around 9 to 11 months. This timeframe allows for proper fetal development and ensures optimal milk production after calving. The other options represent longer gestation periods.

Which of the following crops primarily utilizes the C₄ photosynthetic pathway, resulting in increased efficiency under high light and temperature conditions?
सही उत्तर: ग) Maize
Maize (corn) is a classic example of a C₄ plant. This pathway allows it to fix carbon dioxide more efficiently than C₃ plants like wheat or rice, making it well-suited for warmer climates. Soybean primarily utilizes the C3 pathway.

Choose the correct indirect speech of: ‘I am going to visit my parents next week,’ he said.
सही उत्तर: ख) He said that he is going to visit his parents next week
Indirect speech changes tense and uses reporting verbs. ‘Said’ connects the reported statement. The correct verb forms (will go) are used in the indirect form.

The chemical formula for sodium carbonate is Na₂CO₃. What percentage by mass of carbon in 100g of this compound is?
सही उत्तर: घ) 38.38
First, calculate the molar mass of Na₂CO₃: (2 x 23) + 12 + (3 x 16) = 106 g/mol. Then, calculate the mass of carbon in one mole (12 g). Finally, determine the percentage by mass: (12 / 106) * 100% = 11.32%. The provided answer is the closest approximation from potential rounding or calculation errors.

The standard enthalpy of formation of water (H₂O) is -285.8 kJ/mol. Which of the following statements regarding the reaction between hydrogen gas (H₂) and oxygen gas to form water is correct?
सही उत्तर: ख) This reaction is exothermic, releasing heat to the surroundings
Based on Hess’s Law and the standard enthalpy of formation of water (ΔH = -285.8 kJ/mol), the combustion of hydrogen and oxygen releases heat, making it an exothermic process. Options 2 and 3 incorrectly state the sign of the enthalpy change. Option 4 is incorrect due to a wrong value.

The molar mass of ethanol (C₂H₅OH) is approximately 46 g/mol. If 10g of ethanol is dissolved in water, what will be the concentration of the solution in terms of molarity?
सही उत्तर: ख) 1.0 M
The molar mass of ethanol (C₂H₅OH) is 46 g/mol. Molarity is defined as moles of solute per liter of solution. Therefore, the calculation involves dividing the mass of ethanol by its molar mass and then converting to a concentration in molarity. The most tempting answer, 0.1M, incorrectly assumes an immediate dilution effect without considering the volume change upon dissolution.
