Propanone is more soluble in water compared to propane mainly because propanone cannot hydrogen bond with themselves but can hydrogen bond with water molecules. One of the slightly positive hydrogen atoms in a water molecule can be sufficiently attracted to one of the lone pairs on the oxygen atom of propanone. In order for 3-hexanol to bond with water, the van der Waals forces must be broken and also the stronger hydrogen bonds of water molecules and it needs a great amount of energy.
Answer:
The sand has a higher specific heat
Explanation:
The answer is that the sand would have a higher specific heat than water because water requires a lot of heat to raise its temperature while sand needs less heat to change it as water has a high heat capacity that allows it to maintain its temperature within a range.
These are usually added to a solution as they contain trappedair which
helps in the reflux process.
The high surface area ensures it acts as nucleation sites and the best time
to dd is when the temperature of the solution is still low for best results.

635 g
635 g/cm3
634.5 ml
Answer:
JUST B
Explanation:
The mass of 235 cm³ of aluminum, which has a density of 2.70 g/cm³, is calculated to be 634.5 g using the formula Mass = Density × Volume.
To find the mass of a given volume of a substance, you can use the formula: Mass = Density × Volume. In this case, the density of aluminum is given as 2.70 g/cm³ and you need to find the mass of 235 cm³ of aluminum.
Substitute the given values into the formula:
Mass = 2.70 g/cm³ × 235 cm³ = 634.5 g
Therefore, the mass of 235 cm³ of aluminum is 634.5 g.

b. churning, or mixing, food
c. opening and closing the stomach
d. absorbing nutrients
The muscles in the stomach aid in digestion by churning, or mixing, food. Hence, option C is the correct answer.
Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive.
The stomach is a muscular sac that lies between theesophagus and the small intestine in the upper abdomen.
The stomach is not the only part of your digestive system that absorbs food but rather is a part of the digestive system and important for churning food into a consistency that is easier to digest for the rest of your intestines.
Hence, option C is the correct answer.
