Why is the melting point of ethane much lower than the melting point of methane?
The melting point of ethane and methane is almost the same.Ethane - mp = -183 oCMethane - mp = -182 oCHowever, the boiling point of ethane is higher at -88.6 oC compared to methane at -162 oC.Generally, the larger the molecule the higher the boiling point. This trend can be seen in the hydrocarbon series.Methane (molar mass, Mr = 16) bp = -162 oCEthane (Mr = 30) bp = -88.6 oCPropane (Mr = 44) bp = -42.2 oCButane (58) bp = -0.5 oCPentane (72) bp = 36.3 oCand so on.The trend is that boiling points increase as size of molecule increases. The intermolecular bonds are stronger as the larger molecules can form temporary electrostatic interaction areas. These intermolecular forces are called van der Waal forces or dispersion forces.
What is the molecular formula of a substance that has an empirical formula of C2H5 and a molecular mass of 58 grams per mole?
If C2H5 was the molecular formula its molecular mass would be 29 ( 12 x 2 + 5 x 1) However, 29 x 2 = 58 the actual molecular mass. So we double up the atoms in C2H5 to C4H10 . C4H10 is the molecular formula.
What city is at 23 degrees N and 58 degrees E?
There's no city there. That point is in northern Oman, about 56 miles southwest of Muscat.
What city is 23 north latitude 58 east longitude?
Ad Dakhiliyah ‍Governorate, Oman
What is 2000 times 58?
2000 * 58 = 116,000
What would be the boiling point of methylene chloride at 670 mm Hg?
53o CIt will be somewhat lower than 329 K (57oC), the boiling point at standard 760 mmHg, but it is not calculable. Some suggest -3 K, lower, so about 54oC but this couldn't be verified.
What is cerium's boiling point?
Cerium's boiling point is 6,229 degrees Fahrenheit. Cerium is classified as a rare earth element, and its atomic number is 58. Its melting point is 1,463 degrees Fahrenheit.
How does molecule size affect boiling point?
With a bigger size there are stronger London forces. London forces are also known as Dispersion forces and van der Waal forces. These forces become stronger as the size of the molecule increases. Butane, C4H10, is a gas with a relative size of 58 and a boiling point of ~ -1 ºC. Octane, C8H18, is a liquid with a relative size of 114 and a boiling point of 125 ºC. The two molecules differ in size only but as octane is bigger it has a higher boiling point due to the dispersion forces.
What is the halfway point between 57 and 58?
The halfway point between 57 and 57 is (57 + 58) ÷ 2 = 57.5
Is butane gas less volatile than propane?
Yes, the molecular mass of propane is 44 while that of butane is 58, higher is the molecular mass of an alkane higher would be the boiling point therefore less would be the volatility.
If a substance freezes aat -58 c then what would it melt at?
The temperature of freezing and melting is the same. It depends on whether heat is being taken away (freezing) or added (melting).
Where is the melting point for gypsum?
58 degrees Celsius
What liquid metal has a 800 celsius melting point?
Cerium (58) has a melting point of 799 deg C.
What country is 22 n degrees 58 degree w?
There is no country on that point. That point is in the middle of the atlantic ocean.
How change 0.58 dollars to cents?
multiply by 100 so it will be 0.58x100=58 so 0.58 dollars is 58 cents.
What are the forces of two charges of 58 c and 2 point 1c if they are separated by a distance of 3 point 2m?
multiply charges divide by disatance squared. 58*2.1=121.8 121.8/3.2^2=11.8945
