Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 500.
yaroslaw [1]

Answer:

12. is the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.

Explanation:

2NH_3(g)\rightleftharpoons N_2(g)+3H_2(g)

initially

3.0 atm      0              0

At equilibrium

(3.0-2p)     p               3p

Equilibrium partial pressure of nitrogen gas = p = 0.90 atm

The expression of a pressure equilibrium constant will be given by :

K_p=\frac{p_{N_2}\times (p_{H_2})^3}{(p_{NH_3})^2}

K_p=\frac{p\times (3p)^3}{(3.0-2p)^2}

=\frac{0.90 atm\times (3\times 0.90 atm)^3}{(3.0-2\times 0.90 atm)^2}

K_p=12.30\approx 12.

12. is the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.

Calcium chloride forms an ionic solid. How are the particles held together
xxMikexx [17]

Answer: D. Calcium and chloride atoms are held together by electrostatic

forces in a regular pattern.

  • It is a solid, so the particles are held together in a regular way. Eliminate B and C.
  • Also, there are no covalent bonds, so eliminate A.

An atom of 65as has a mass of 64. 949563 amu. mass of1h atom = 1. 007825 amu mass of a neutron = 1. 008665 amu. calculate the ma
sukhopar [10]

The mass defect of an atom is 10.672592 amu/atom.

The mass defect is the discrepancy between the nucleus of an atom's anticipated mass and its actual mass. This discrepancy is due to the binding energy of a system, which might manifest as excess mass.

A key characteristic of a nucleus is the nuclear mass defect, which has a set value equal to a specific amount of binding energy for that nucleus.

The binding energy (BE) of a nucleus is the mass defect multiplied by the square of the speed of light or the energy released during the nucleus' formation.

Mass of the atom = 64.949563 amu

Mass of the proton = 1.007825 amu

Mass of the neutron = 1.008665 amu

Arsenic has 33 protons and 42 neutrons.

Mass defect = Mp + Mn - MA

                    = 33 × 1.007825 + 42 ×  1.008665 - 64.949563

                    = 33.258225 + 42.36393 - 64.949563

                    = 10.672592 amu/atom

Therefore, the mass defect of atom is 10.672592 amu/atom.
