Answer:

Intermolecular forces are the interactions that exist between molecules. Hydrogen bond typically occurs when a hydrogen atom bonded to O, N, or F, is electrostatically attracted to a lone pair of electrons on an O, N, or F in another molecule. Polarizability is a measure of how the electron cloud around an atom responds to changes in its electronic environment. London forces, also known as dispersion forces are weak interactions caused by the momentary changes in electron density in a molecule. Dipole-dipole are the attractive forces between the permanent dipoles of two polar molecules. All compounds exhibit van der Waal forces.

Explanation:

Molecules interact each other by intramolecular forces. Among them are van der Waal forces, which are weak interactions, so all compounds interacts by this kind of forces. London forces (dispersion forces) are comprised in the group of van der Waal forces, so they are weak forces. Hydrogen bond is a stronger force, which is resposible for the structure of ice and properties of liquid water (water molecules interacts each other by hydrogen bond), so they are very important forces!

Polarizability is the trend of a molecule to became more polar (when exist a net charge differences in the molecule).

How many liters of fluorine gas, at standard temperature and pressure, will react with 23.5 grams of potassium metal?
ArbitrLikvidat [17]
The balanced chemical reaction is written as:

<span>2K + F2 ---> 2 KF

We are given the amount of potassium metal to be used in the reaction. This will be the starting point for the calculation. We do as follows:

23.5 g K ( 1 mol / 39.1 g ) ( 1 mol F2/2 mol K ) ( 22.4 L / 1 mol ) = 13.46 L F2

7) What is the hydrogen concentration of a solution with a pH of 2.1? *
lesya [120]

Answer:

Hydrogen concentration = 7.94×10^-3 M

Explanation:

from potenz Hydrogen ( pH ) definition

pH = -log[H+]

2.1 = -log[H+]

2.1/-log = -log[H+]/-log

10^-2.1 = [H+]

[H+] = 7.94×10^-3M

2.56 g of hydrogen reacts completely with 20.32 g of oxygen<br> to form X g of water. X = g
Brilliant_brown [7]

Answer:

Mass of water produced is 22.86 g.

Explanation:

Given data:

Mass of hydrogen = 2.56 g

Mass of oxygen = 20.32 g

Mass of water = ?

Solution:

Chemical equation:

2H₂ + O₂   →  2H₂O

Number of moles of oxygen:

Number of moles = mass/ molar mass

Number of moles = 20.32 g/ 32 g/mol

Number of moles = 0.635 mol

Number of moles of hydrogen:

Number of moles = mass/ molar mass

Number of moles = 2.56 g/ 2 g/mol

Number of moles = 1.28 mol

Now we will compare the moles of water with oxygen and hydrogen.

                    O₂            :            H₂O

                     1              :             2

                  0.635        ;            2×0.635 =  1.27

                   H₂             :              H₂O

                    2              :              2

                 1.28            :           1.28

The number of  moles of water produced by oxygen are less thus it will be limiting reactant.

Mass of water produced:

Mass = number of moles × molar mass

Mass = 1.27 × 18 g/mol

Mass = 22.86 g

Describe the distribution of mass within an atom
san4es73 [151]

Answer:

The nuclei of most atoms also contain neutrons . The masses of subatomic particles are very tiny. ... Since the nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus. Protons and electrons have electrical charges that are equal and opposite.
