suppose 7.26 g of ammonium chloride is dissolved in 150. ml of a 0.50 mm aqueous solution of potassium carbonate.
Mass of ammonium chloride (NH4Cl) = 11.4 grams
Volume of 0.3 M aqueous solution of potassium carbonate (K2CO3) = 250 mL = 0.250L
Step 2: The balanced equation
2NH4Cl + K2CO3 → 2KCl + (NH4)2CO3
Step 3: Calculate moles of (NH4)Cl
moles (NH4)Cl = 11.4 grams /53.49 g/mol
Moles (NH4)Cl = 0.213 moles
Step 4: Calculate moles of K2CO3
Moles K2CO3 = Molarity * Volume
Moles K2CO3 = 0.3M * 0.250 L = 0.075 moles
Step 5: Calculate moles (NH4)Cl at the equilibrium
For 2 moles (NH4)Cl consumed, we need 1 mole of K2CO3 to produce 2 KCl and 1 mole of (NH4)2CO3
(NH4)2CO3l will dissolve in 2NH4+ + CO32-
Moles (NH4)2Cl = 0.213 moles - 2*0.075 = 0.063 moles
Moles NH4+ = moles (NH4)Cl = 0.063 moles
Step 6: Calculate Molarity of NH4+
Molarity = Moles / volume

There are two components in an aqueous solution: the solute and the solvent. You must be familiar with these two fundamental terminology for solution concentration. The amount of solute in the solution must always be recorded. The quantity of a solute in a solvent is what we refer to in chemistry as the concentration of a solution. We refer to a solution as being concentrated when there is more solute present. Conversely, we refer to a solution as being diluted when it contains more solvent.

The Glycolysis produces pyruvate.
What is pyruvate?
Pyruvate is a three-carbon molecule which is the end product of glycolysis, the first step in the breakdown of glucose for energy. It is also the starting point for the Krebs cycle, the second stage of cellular respiration. Pyruvate is formed from the cleavage of the six-carbon sugar molecule, glucose, and is then further oxidized to form acetyl-CoA and enter the Krebs cycle. The enzymes responsible for pyruvate production are known as pyruvate kinases and are found in most eukaryotic cells. Pyruvate is an important molecule in the production of energy within the cell, as it acts as both a source of energy and a precursor to other metabolic pathways. Additionally, pyruvate is involved in the synthesis of fatty acids, amino acids, and other biomolecules. Pyruvate is also used in the fermentation process to produce lactic acid and ethanol.
The pyruvate dehydrogenase (PDH) enzyme is part of the multienzyme PDC, which catalyzes the physiologically irreversible decarboxylation of pyruvate to acetyl-CoA and is often referred to as a 'gatekeeper' in the oxidation of carbohydrate.

Use MO diagrams to place B2+, B2, and B2- in order of (a) decreasing bond energy; (b) decreasing bond length.
We use the MO diagram for a homonuclear diatomic species (since C and N are neighbours, we treat them as the "same").
The first two electrons contribute to bonding. The next two are anti-bonding.
The next six contribute to bonding, and the following six are anti-bonding.
So, if we start with CN+, which has 4+5-1 (8) valence electrons, we note that the first two electrons contribute to bonding, while the next two cancel this out; the next four contribute to bonding, so the bond order is 4/2 = 2.
If we add one more electron to get CN, there are now 5 bonding electrons, giving bond order 5/2=2.5.
Adding one more to give CN- would give the bond order 6/2 = 3. (If we added more electrons, each one would lower the bond order.)

The wavelength of radiation required to ionize b4 is therefore equal to 4.51 kj/mol / 10.8 eV, or 0.42 nm.
What is radiation?
Based on the energy of a radiated particles, radiation is frequently divided into ionising and non-ionizing categories. More than 10 eV is carried by ionising radiation, which is sufficient to ionise atoms as well as molecules and rupture chemical bonds. Due to the significant differences in how harmful these substances are to living things, this distinction is crucial. Radioactive substances that emit radiation in the form of helium nuclei, electrons as well as positrons, or photons are frequently sources of ionising radiation.
The ground state ionization energy of b4 is the energy required to remove an electron from the atom in its ground state. This energy is usually expressed in kilojoules per mole (kj/mol) and is equal to the amount of energy required to ionize one mole of b4 atoms.
The wavelength (λ) of radiation required to ionize b4 is the energy of the photon of radiation divided by the ground state ionization energy of b4. This wavelength is usually expressed in nanometers (nm).
The ground state ionization energy of b4 is 10.8 eV, which is equal to 4.51 kj/mol. The wavelength of radiation required to ionize b4 is therefore equal to 4.51 kj/mol / 10.8 eV, or 0.42 nm.
