Answer:
The answer is D. Hydroelectric
Answer is: 31,45%.
mrs₁(C₉H₁₆O₄-<span>azelaic acid) = 12g.
mr</span>₂(C₉H₁₆O₄) = 50g.
ω₂(C₉H₁₆O₄) = 15% = 0,15.
mrs₂(C₉H₁₆O₄) = mr₂·ω₂ = 50g·0,15 = 7,5g.
mrs₃(C₉H₁₆O₄) = mrs₁ + mr₂ = 12g + 7,5g = 19,5g.
mr₃ = mr₂ + mr₂ = 50g + 12g = 62g.
ω₃ = mrs₃÷mr₃ = 19,5g ÷ 62g = 31,45% = 0,3145.
The relationship between the surface area of a molecule and the strength of the intermolecular forces states that the larger the surface area, the weaker the intermolecular forces; Correct answer is True.
<h3>What are intermolecular forces?</h3>
Intermolecular forces are the forces that exist between the molecules of a substance.
The intermolecular forces present in a substance depends on the nature of the substance.
Also, the surface area of a substance affects the intermolecular forces present in the substances.
The greater the surface area, the stronger the intermolecular forces.
In conclusion, intermolecular forces exists between molecules of a substance.

When a block of ice is placed in a frying pan, it is first in a solid state, meaning that the particles are moving slowly and are tightly compacted together as well as vibrating. As the the temperature of the pan increases, the state of matter will go from a solid to a liquid, which will cause the thermal energy in the ice cube to increase and the particles will go from a vibrating state, to sliding state. By this time the ice will now be water. As the temperature of the pan continues to increase, the water will eventually become water vapor and turn into a gas because as the particles are heated, they will move faster causing them to expand.
Is B. The number of the atomic mass can increase or decrease because the number of neutrons is different.
