The amount of energy required to remove an electron from an atom. 2 ionization energy

A bond where electrons are shared unequally, resulting in a positively charged end and a negatively charged end of the molecule, 4 polar covalent bond

The tendency of an atom to attract a pair of electrons and bond with another atom; increases from bottom-left toward top-right of the periodic table. 3. Electronegativity

A bond where electrons are shared equally, or polar bonds in the molecule cancel each other out. 5. Non polar covalent bond

Shell or energy level where electrons are found. 1. Orbital

A sample of gas occupies a volume of 73.7 mL. As it expands, it does 133.7 J of work on its surroundings at a constant pressure

katen-ka-za [31]

In thermodynamics, work performed by a system is the energy transferred by the system to its surroundings. It can be calculated by the expression:

W = PdV

Integrating,

We will have,

W = P(V2 - V1)
133.7 (1 litre-atm / 101.325 Joule) ( 760 Torr / atm ) = 783 (V2 - .0737 )
V2 = 1.35 L

Hope this answers the question. Have a nice day.

The empirical formula of styrene is CH; its molar mass is 104.1 g/mol. What is the molecular formula of styrene?

Natalija [7]

You got the answer correct. If you would double check
given:C (12 g/mol) H (1 g/mol).

12(8) + 1(8) = 104 g/mol

and for C2H4
12(2)+1(4) = 28g/mol

Also, chemical formula of styrene is C6H5CH=CH2.

Which type of intermolecular attractive force operates between (part A) all molecules, (part B) polar molecules, (part C) the hy

nydimaria [60]

Answer:

PART A: The LDF occurs between all molecules. Dispersion forces result from shifting electron clouds, which cause weak, temporary dipole.

PART B: Dipole dipole operates only between polar molecules. This is when two polar molecules get near each other and the positively charged portion of the molecule is attracted to the negatively charged portion of another molecule.

PART C: Dipole dipole and in some cases hydrogen bonding operate between the hydrogen atom of a polar bond and a nearby small electronegative atom. Only if the atom bonded to it were F, O or N it would be hydrogen bonding. Otherwise it is dipole dipole.

Convert -12.00 degrees Celsius to the unit Kelvin. 296.15 K 261.15 K -285.15 K -162.85 K

Gre4nikov [31]

To convert Celsius to kelvin, we need to know the formula. Kelvin = Celsius + 273.15. Now, we can figure out how many degrees kelvin -12 degrees Celsius is.

Kelvin = -12 + 273.15

Kelvin = 261.15
