Ammonia, NH3 is a common base with Kb of 1.8 X 10-5. For a solution of 0.150 M NH3:

Chemistry

Vesnalui [34]3 years ago

The concentrations : 0.15 M

pH=11.21

<h3>Further explanation</h3>

The ionization of ammonia in water :

NH₃+H₂O⇒NH₄OH

NH₃+H₂O⇒NH₄⁺ + OH⁻

The concentrations of all species present in the solution = 0.15 M

Kb=1.8 x 10⁻⁵

M=0.15

\tt [OH^-]=\sqrt{Kb.M}\\\\(OH^-]=\sqrt{1.8\times 10^{-5}\times 0.15}\\\\(OH^-]=\sqrt{2.7\times 10^{-6}}=1.64\times 10^{-3}

\tt pOH=-log[OH^-]\\\\pOH=3-log~1.64=2.79\\\\pH=14-2.79=11.21

The above is balanced equations for the reactions mentioned in the question.

<h3>What is balanced equation?</h3>

A balanced reaction equation demonstrates atom conservation by displaying not only the several forms the reactants might take but also their amounts and quantities.

For instance, H + O H0 is the equation for the reaction between hydrogen and oxygen in its most basic form.

However, water is H₂O (the reaction proportion is 2:1, not 1:1), hence the equation needs an adjust: H₂ + O → H₂O.

However, due to the fact that oxygen occurs as diatomic molecules (O2), that is not yet the correct, final form. So put that: H2 + O2 H2O.

The amount of atoms on the left and right sides do not match, so this is not good enough. It is also not yet in balance. The coefficients must be changed in order for the right numbers to appear everywhere:

2H₂ + O₂ → 2H₂O

It works like this: on the left, there are 4 H atoms and 2 O atoms, and on the right, there are 4 H atoms and 2 O atoms.

Continuing from the last question, what is the new pressure inside the container? Hint: Did we use up all of the reactants?
Leya [2.2K]

If all the reactors are used, the pressure inside the flask will most likely increase to 4 atm.

<h3>What is atmospheric pressure?</h3>

Atmospheric pressure is a force per unit area exerted by the air in the atmosphere on the Earth's surface. The value of atmospheric pressure above sea level is 1013.25 hPa.

<h3>What influences the variation of atmospheric pressure?</h3>

The atmospheric pressure varies from different meteorological factors such as:

  • Decreases with altitude.
  • It varies according to latitude, the lowest atmospheric pressure at sea level is reached in the equatorial latitudes.
  • The equatorial zone has high atmospheric pressures for dynamic reasons derived from the Earth's rotation.

According to the above, if all the reactors are used at atmospheric pressure, it will most likely increase.

Note: This question is incomplete because some information is missing. However I can answer it based on my prior knowledge.

If phosphorous has 5 valence electrons, how many does sulfur have?
VARVARA [1.3K]

Answer:

6

Explanation:

The atomic number for phosphorous is 15, meaning that it has 15 electrons (and protons). The first and second shells would be filled up with 2 and 8 electrons respectively, leaving 5 which goes on the third shell, which is also the valence shell, meaning phosphorous has 5 valence electrons.

Since the atomic number of sulfur is 16, the first and second shells are also filled up with 2 and 8 electrons respectively, leaving 6 to be on the third shell, the valence shell. Hence, sulfur has 6 valence electrons.
