<h2>
Answer:</h2>
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
<h2>
Explanation:</h2>
Chemical bonds are formed by gaining, yielding or sharing electrons to reach stable electronic configurations such as those of noble gases. Electropositive atoms give up electrons to complete the most stable configuration, leaving them with a negative charge defect.

The wavelength of the photon is 1026 Å
Rydberg unit of energy corresponds to the energy of the photon whose wave number is Rydberg constant.
The value for the rydberg constant is 10 973 731.6 m-1
The formula for the rydberg constant for hydrogen is
1 / λ = Rh (1 / n1^2 - 1 / n2^2)
where Rh is the Rydberg constant
For the transition of an electron in a hydrogen atom from n = 1 to n = 3
1 / λ = Rh (1 / 1^2 - 1 / 3^2)
1 / λ = Rh (0.888)
λ = 1.126 / Rh
λ = 1.126 / 10 973 731.6
= 1.026 * 10^-7
= 1026 Å
Hence, the wavelength of the photon is 1026 Å

Answer: 5.844 grams of NaCl needed to make solution.
Explanation:
Answer:
The total pressure in the container at equilibrium is 0.37065 atm
Explanation:
<u>Step 1: </u>Data given
Kp for the decomposition of H2S is 0.795
Only H2S is present at a pressure of 0.203 atm
<u>Step 2:</u> The balanced equation
H2S (g) → H2(g) + S(g)
<u>Step 3: </u>Calculate partial pressure of H2 and S
Initially, there is no H2 and S, they have no pressure
There will react X
The pressure at the equilibrium we have:
H2: X
S: X
H2S: 0.203 - X
Kp = (pH2)(pS)/(pH2S)
0.795 = (x)(x)/(0.203 - X)
X = 0.16765
<u>Step 4:</u> Calculate total pressure at equilibrium:
Total pressure = the partial pressure of H2 + partial pressure of S + partial pressure of H2S
P = X + X + (0.203 - X)
P = 0.16765 + 0.16765 + (0.203 - 0.16765)
P = 0.37065 atm
The total pressure in the container at equilibrium is 0.37065 atm
