C. Earth's gravitational force is stronger than the Moon's.
Since Earth has a far larger mass than the Moon, its gravitational force is also higher.
Due to its higher oxygen content and based on its structure dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.
<h3>What is the calorific value of a fuel?</h3>
The calorific value of a fuel is the amount of heat energy released from the combustion of the fuel under standard conditions.
Dietheylene glycol, isopropanol and paraffin wax are all used as fuels.
However, due to it higher oxygen content and based on its structure, diethethylene glycol has a higher calorific value than either isopropanol or paraffin wax.
Therefore, dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.

A gram of NaOH required to neutralize 700 ml HCL is <u>84 grams.</u>
Neutralization or neutralization is a chemical response in which an acid and a base react quantitatively with each different. I
Moles of solute = Molarity × Liters of solution
= 3 × 0.7 L
= 2.1 mole
The molar mass of NaOH = 40
mass of NaOH = 40 × 2.1 g
=<u> 84 gram.</u>
A neutralization response may be described as a chemical reaction in which an acid and base quantitatively react together to shape salt and water as products. In a neutralization response, there's a combination of H+ ions and OH– ions that form water.
A neutralization response is when an acid and a base react to shape water and salt and includes the mixture of H+ ions and OH- ions to generate water. The neutralization of a sturdy acid and robust base has a pH equal to 7.
