Explanation:
Adding heat can cause ice (a solid) to melt to form water (a liquid). Removing heat causes water (a liquid) to freeze to form ice (a solid). When water changes to a solid or a gas, we say it changes to a different state of matter. Even though the water's physical form changes, its molecules stay the same.
Answer:
energy that is transmitted in the form of electromagnetic waves.
Explanation:
Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum.
<span> If the solution is 95% by weight, that means that in 100 grams of solution you have 5 grams of water and 95 grams of ethanol.
Convert each of these masses to moles by dividing each mass by the molar mass of the compound.
5 g/18 g/mol = 0.278 mol water
95 g / 46g/mol = 2.065 mol ethanol
Mole fraction water:
= mol water / total moles
= 0.278/ (0.278 + 2.065)
= 0.119 </span>
