Ethylene glycol (OH—CH2—CH2—OH) is used as an antifreeze. (Its boiling point is 197 ◦C and freezing point is –17.4 ◦C.)(a) Look up the density of ethylene glycol in the CRC Handbook or other tables and write a general formula for the freezing point of a mixture of X mL of ethylene glycol in 1.00 L of water for X in the range 0–100 mL.(b) If the lowest expected temperature is about –10 ◦C, what is the minimum amount of ethylene glycol (milliliters ethylene glycol per liter of H2O) you need in your coolant?(c) What is the boiling point of the coolant that contains 300 mL of ethylene glycol per liter of water?

What is the molarity of 60.0 grams of naoh dissolved in 750 milliliters of water? a) 1.1 m b) 2.0 m c) 12 m d) 75 m

How do temperature and salinity affect deepwater currents? 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.
