Answer:
Entropy change is favorable when a nonpolar molecule is transferred from water to a nonpolar solvent.
Explanation:
A nonpolar molecule is not miscible in water (polar solvent). Therefore, when mixed together, each specie will cluster together and solvation will not happen.
However, when you tranfer the nonpolar molecule to a nonpolar solvent, the solvent molecules will interact with the nonpolar molecule. This will increase entropy as the level of disorder will increase with solvation.
Answer: Metals are shiny and lustrous with a high density. They have very high melting and boiling points because metallic bonding is very strong, so the atoms are reluctant to break apart into a liquid or gas.

<span>They follow mostly from pleistocene climate and topography, so are in general less tightly controlled by bedrock than others. Most terrestrial fossil remains are found either in ponds dating from the receding of previous glaciers or isolated teeth or bone fragments in glacial till. Some important faunas, however, are preserved in pleistocene caves.

Answer:
Mass = 6.79 g
Explanation:
Molarity = 0.155
Volume = 0.75L
Mass = ?
The relationship between these quantities is given as;
Molarity = Number of moles / Volume
Number of moles = Volume * Molarity
Number of moles = 0.75 * 0.155 = 0.11625 moles
Number of moles = Mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 58.44277 g/mol * 0.11625 mol
Mass = 6.79 g
Answer:
0.954
Explanation:
1000 grams is 1 kg
954 grams is 954/1000 kg or 0.954
