Yakvenalex [24]3 years ago
4 0
Niels Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level-- or orbit-- to another.

Explain the kinetic theory of gases Forces between molecules
lilavasa [31]

According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure.

According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure. The assumption that matter is made up of microscopic particles that are always in motion forms the foundation of the kinetic-molecular theory, which explains the states of matter.

The observable characteristics and behaviours of solids, liquids, and gases are explained by this theory. The kinetic theory of gases has three primary parts, which are as follows: 1) Neither energy is gained nor lost when molecules collide. 2) In a container, the space occupied by gas molecules is extremely minimal. 3) These molecules move in a straight line at all times.

When a 6.00 g sample of KBr is dissolved in water in a calorimeter that has a total heat capacity of 2.71 kJ ⋅ K − 1 , the tempe
Umnica [9.8K]

Answer:

Molar heat enthalpy of KBr = -19.89 kJ/mol

Explanation:

Change in temperature (Δt) = 0.370 K

Heat capacity = 2.71 kJ ⋅ K^-1

Heat absorbed by calorimeter = heat capacity × change in temperature

                                               = 2.71× 0.370

                                               = 1.0027 kJ

Molar mass of KBr = 119 g/mol

No. of moles of KBr = 6.00/119

                               = 0.0504 mol

Heat absorbed by the calorimeter is given by KBr.

Now calculate the heat released by per mol of KBr as follows:

Heat released by per mol of KBr = 1.0027 kJ / 0.0504 mol

                                                   =19.89 kJ/mol

Heat is released therefore, sign will be negative.

Molar heat enthalpy of KBr = -19.89 kJ/mol
