Gas is released by addition of the tablet into water. It is possible to capture the gas emitted and test it - it will be carbon dioxide.

Do the ch3f molecules appear to attract each other much? briefly describe their interaction.
suter [353]

Neither attract much nor allows it be free.

How the molecules behave in such way?

Because fluorine has a higher electronegativity than carbon and hydrogen, CH3F possesses a non-zero dipole moment. As a result, fluorine draws a partial negative charge whereas other atoms (such as carbon or hydrogen) draw a partial positive charge, leading to a non-zero dipole moment in CH3F. Lewis' structure, CH3F, is made up of one carbon atom, three hydrogen atoms, and one fluorine atom. Carbon is the key atom in the CH3F lewis structure because it is the least electronegative. The CH3F lewis dot structure consists of 3 lone pairs and a total of 4 bound pairs.

Properties of CH3F

  • It molar mass is 34.03 g/mol.
  • The density of CH3F is 1.4397 g/L and 0.557 g/cm³ at saturated pressure and temperature.
  • The melting point of CH3F is -137.8ºC and the Boiling point is -78.4ºC.
  • Its vapor pressure is 3.3 MPa.
  • Its IUPAC name is Fluoromethane.

A gas has an empirical formula CH4. 0.16g of the gas occupies a volume of 240cm^3 What is the molecular formula of the gas???.
yulyashka [42]

Explanation and answer:

The molar volume of a gas is 22.4 L at 0 deg. C.

So the molar mass of the gas is, by proportion,

0.16 g * (22400 mL)/(240 mL) = 14.93 g

The molar mass of (CH4)n = 12+4(1) = 16.

So n = 15.93/16 = 1, or the molecular formula is CH4.

Note: The temperature at which the volume was observed was not given.  If 240 cm^3 was observed at 20 deg.C, then the volume at 0 deg.C would be

V=240*(273+0)/(273+20) = 223.6

The molar mass = 0.16*22400/(223.6) = 16.03

which gives n = 16/16.03 = 1 again, but more accurately.
