A buffer solution is prepared that is 0.18 M NH3 and 0.27 M NH4Cl. What is the pH of this buffer? Kb for NH3 is 1.8 x 10-5
The correct answer is: 9.08
Can someone explain how to do this for me?

Answers

The pH of acid is between 0-7 on pH scale while for base pH range is from 7-14. Therefore, the pH of this buffer is  5.14. pH is a unitless quantity.

What is pH?

pH is a measurement of amount of hydronium ion H₃O⁺ in a given sample. More the value of hydronium ion concentration, more will be the solution acidic.

On subtracting pH from 14, we get pOH which measures the concentration of hydroxide ion in a given solution. pH depend on the temperature. At room temperature pH scale is between 0 to 14. pH of neutral solution is 7.

0.18 M =NH₃

0.27 M= NH₄Cl.

Kb of NH₃ = 1.8 × 10⁻⁵

pKb = - log (kb)

      = - log (1.8 × 10⁻⁵)

       = 4.74

Using Henderson equation

pH = Pkb +ln [ NH₄Cl ]/ [NH₃]

    = 4.74 + ln (0.27 /0.18)

    = 5.14

Therefore, the pH of this buffer is 5.14.

If an atom, such as hydrogen, is able to form a covalent bond, describe what happens when the

Answers

The potential energy between the nuclei is minimized and the orbital shells overlap.

What is a covalent bond?

We know that a covalent bond is the kind of bond that is formed when there is the combination of two atoms when there is the overlap of the orbitals of the two atoms. In the case of the hydrogen atoms, we can say that there is a bond as we notice that the two atomic orbitals have become overlapped on each other.

Let us note that when the two atoms are still far from each other, the potential energy between the atoms is high and as such the atoms of the element would tend to repel each other.

As the two atoms begin to approach each other, the repulsion between the nuclei of the elements is seen to become minimized and the bond is now seen to be formed as the atomic orbitals become overlapped.

Methyl esters are created when carboxylic acids and diazomethane interact. Diazomethane is used to create methyl esters and has a high degree of reactivity.

Diazomethane reacts swiftly and extremely effectively, producing just N2 as a byproduct, making it an appealing alkylating agent for carboxylic and phenols (Black, 1983). As it responds, its inherent yellow color releases, automatically indicating the status of the reaction. Methyl esters are created when carboxylic acids and diazomethane interact. Diazomethane is created in-situ and then interacted with the carboxyl group right away to create the methyl ester due to its high reactivity.

Stoichiometry is the study and calculation of quantitative (measurable) relationships of the reactants and products in chemical reactions (chemical equations).

According to this question, nitrogen gas completely reacts with 2.8 moles of hydrogen as follows:

N₂ + 3H₂ → 2NH₃

Based on the above equation, 1 mole of nitrogen gas reacts with 3 moles of hydrogen. This means that 2.8/3 moles = 0.933 moles of nitrogen will react with 2.8 moles of hydrogen.

The alkali metals, found in group 1 of the periodic table, are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they readily lose that one electron to form ionic bonds with other elements. Sodium (na) is an alkali metal that bonds with chlorine (cl), a halogen, to form table salt (nacl). Based on what the periodic table can tell you about these two elements, explain how and why they bond to form nacl.

Answers

Answer:

The periodic table is a useful tool for understanding the properties of elements and predicting how they will interact with each other. The alkali metals, including sodium, are located in group 1 of the periodic table. These elements have only one electron in their outermost shell, which makes them very reactive. They readily lose this outer electron to form an ion with a positive charge, which is called a cation.

Chlorine, on the other hand, is a halogen located in group 17 of the periodic table. Halogens have seven electrons in their outermost shell, which makes them highly reactive. They readily gain an electron to form an ion with a negative charge, which is called an anion.

When sodium and chlorine interact, they form an ionic bond to create the compound sodium chloride, or table salt. In this process, sodium loses its outer electron to form a sodium cation, and chlorine gains an electron to form a chlorine anion. The positive sodium cation is then attracted to the negative chlorine anion, forming an ionic bond. This bond is strong enough to hold the two ions together, creating a stable compound.

Therefore, sodium and chlorine bond to form table salt because they have the opposite charges and opposite reactivities that are necessary to form an ionic bond. The periodic table can help us understand this bonding process by providing information about the number of electrons in the outermost shell of each element, which determines their reactivity and ability to form ions.

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, in below given ways, periodic table helps in explaining the reason of bonding.

What is chemical Compound?

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

An ionic compound is a metal and nonmetal combined compound.  Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.

Because sodium and chlorine have the opposing charges and reactivities required to create an ionic bond, they bind to make table salt. The periodic table can help us comprehend this bonding process by revealing the amount of electrons in each element's outermost shell, which governs their reactivity and capacity to generate ions.

Therefore, in above ways, periodic table helps in explaining the reason of bonding.

However, the number of moles of a substance can be calculated by dividing the number of molecules of a substance by Avogadro's number;

no of moles = 7.60 × 10²⁰ ÷ 6.02 × 10²³

no of moles = 1.26 × 10-³ moles

molar mass of hydrogen peroxide = 34g/mol
