3) The following compounds are nonelectrolytes that are soluble in water. Which statement below is true of the colligative properties of these compounds?
acetic acid CH3COOH
glycerol C3H5(OH)3
sucrose C12H22011
urea CH4N20
Acetic Acid would have the greatest boiling point of elevation because is an acid.
Sucrose would have the highest freezing-point of depression because it has the highest
molar mass.
Sucrose would have the highest freezing-point of depression because it has the highest
number of hydrogens.
Each compound would have the same colligative properties.
O Glycerol would have the highest osmotic pressure because is highly viscous.

Which of the following are good traits of a hypothesis? it will be able to be testedit can predict an outcomeit will explain the observationsall of these

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

When the chemicals iron sulfide (fes) and hydrochloric acid (hcl) are combined, bubbles appear from the mixture. 1. does the appearance of bubbles indicate a physical or chemical change? 2. why do the bubbles indicate this change? 3. what property is this?
