How many Cl- bond with one Na+ ion?

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.
