How many grams of ethylene glycol automobile antifreeze C2H6O2 dissolved in 3.80kg of water is needed to lower the freezing point of water in an automobile radiator to 21.0C?

None. The freezing point of pure water is already lower than that.

What is the freezing point of 100 percent Antifreeze?
Original Answer: 100 percent coolant freezing point -60 celcius This is baldly incorrect. 100% solution of ethylene glycol-based antifreeze is approximately -12 degrees celcius, higher for many of the lower quality products (which have a lower concentration of ethylene glycol). The optimum solution is about 60% antifreeze and 40% water. The reason for this is that the two molecule types (ethylene glycol and water) interfere with each other's ability to attract like molecules and crystalize, or freeze. A higher concentration of either liquid will reduce this affect and raise the freezing point. For warmer climates, 20% antifreeze is probably enough - water has a higher capacity for heat than antifreeze does. Running 100% water is not a good idea though, even in the hottest of temperatures. There are (usually) additives in antifreeze that serve to condition and lubricate the cooling system, primarily the water pump. Pure ethylene glycol actually freezes at about 8 degrees fahrenheit.. The key is in the mix.
What does ethylene glycol do to the solution in a vehicles radiator?
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
What is a sentence for the word antifreeze?
A sentence for the word antifreeze may be, " What is the best antifreeze to use in drinking water?" Antifreeze is a liquid which is used to lower the freezing point.
What colligative property is responsible for antifreeze?
Freezing point depression. When a solution is formed the molecules of the solute prevent the solution from freezing at its normal freezing point, it must be colder.
What is the freezing point of a solution made by dissolving 352 g of ethylene glycol in 648 g of water?
-16.3C
What are physical changes of antifreeze when dissolved in water?
will change the boiling and freezing point of the water
How does antifreeze work?
Antifreeze is a liquid added to the cooling system of an automobile to ensure that the water within it does not freeze solid.
Does antifreeze boil at a lower temperatures than pure water?
The mixture of the two liquids (water and antifreeze ethylene glycol))has a higher boiling point and lower freezing point than water alone.

Which compound can be used as the antifreeze in cars radiators by mixing with water?
Any substance that lowers the freezing point of water such as ethylene glycol or propylene glycol which are commonly added to water
State two quantitative physical proparties that change when antifreeze is dissolved in water?
It chances the boiling point of the water, and it changes the freezing point of the water
The hazardous component in most antifreeze is?
Methanol(otherwise known as wood alcohol) and ethylene glycol are the two toxic components in antifreeze. Methanol and ethylene glycol are both acted upon by alcohol dehydrogenase in the cell cytoplasm. This converts these molecules into toxic compounds like formaldehyde and formic acid. Before the advent of fomepizole (an alcohol dehydrogenase blocker), alcohol was given as a treatment for antifreeze ingestion because it competed with methanol and ethylene glycol for alcohol dehydrogenase. Methanol can cause blindness and death. Ethylene glycol crystallizes within the kidney and can cause renal failure and death. Hope that helps.
What is antifreeze made of?
Gasline antifreeze is usually just isopropyl alcohol. Many drugstores sell 97-percent isopropanol, and if you put six ounces of it in a 20-gallon gas tank it will do the same thing as Heet (or whatever brand you like) for less money.
What is the common name that stuff is used to prevent cars from freezing?
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound widely used as an automotive antifreeze and a precursor to polymers.
What are two properties that make ethylene glycol an ideal antifreeze?
Well, when mixed in an ideal solution with water, it has a relatively high boiling point and low freezing point. Also, it doesn't cause rust/corrosion.
Is dry ice capable of freezing antifreeze?
Yes it is capable of antifreeze
Which facts about the use of antifreeze illustrates a rule that governs the physical world?
Antifreeze keeps water from freezing when it is cold out. The antifreeze liquid lowers the freezing point of the water. Even when freezing (to a slurry) it does not form solid ice that can rupture the radiator. The antifreeze combines the water to form a liquid with a lower freezing point than water alone.
