<u>Answer:</u>
The freezing point of a 1.7 mole aqueous ethylene glycol solution is 3.2°C
<u>Explanation:</u>
Moles present in aqueous ethylene glycol solution= m=1.7
Depression constant for water = = 1.8 deg C/m
According to formula
=1.8* 1.7
=3.2
Hence the freezing point of aqueous ethylene glycol solution is 3.2°C

Scientists are able to understand Earth's interior by studying seismic waves. These are waves of energy that travel through Earth, and they move similarly to other types of waves, like sound waves, light waves, and water waves.
Your final answer would be 5. You would divide 200 by 40.
Answer:
Element: Sulfur ; S
Compound: Water ; H2O
Mixture: Gunpowder ; 2 KNO3 + S + 3 C -> K2S + N2 + 3 CO2
Explanation:
An element is a pure substance that cannot be broken down into simpler substances. A periodic table for example has elements.
A compound is a chemical substance that's made of multiple elements held together by chemical bonds. All elements from the periodic table can be combined to make a compound but they have to bond a specific way in order for them to actually make something. Water is the easiest to remember.
A mixture is two or more substances that are physically combined. They are not chemically combined though. There are a few types of mixtures including homogeneous, heterogeneous, etc. Gunpowder is actually a mixture. It contains sulfur, carbon and potassium nitrate.
