allows oxidation of co (carbon monoxide) to less-harmful co₂ (carbon dioxide) allows oxidation of hc (unburned hydrocarbons) to co₂ (carbon dioxide) and h₂o (water)
The oxidation of co (carbon monoxide) to less-harmful co₂ (carbon dioxide) and the oxidation of hc (unburned hydrocarbons) to co₂ (carbon dioxide) and h₂o (water).
What is meant by an oxidation reaction?Oxidation is that the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation number of a molecule, atom or ion is increased. the other process is called reduction, which occurs when there's a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.
Why is it called an oxidation reaction?
The term oxidation was first employed by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it had been realized that the substance, upon being oxidized, loses electrons, and therefore the meaning was extended to include other reactions in which electrons are lost, no matter whether oxygen was involved.

Why are the Lewis Dot Structures for H and He different?
Answer:
The Lewis dot structure for H is H, while the Lewis dot structure for He is He. The difference is due to the different number of valence electrons in each atom. H has one valence electron, while He has two valence electrons.
Explanation:
The explanation for this is that, according to the octet rule, atoms will tend to form bonds until they have eight valence electrons around them. H only has one valence electron, so it can only form one bond. He, on the other hand, has two valence electrons, so it can form two bonds.

What does denature mean?Some proteins in food denature when it is cooked. Because of this, cooked flesh solidifies and boiled eggs become hard. Egg whites, which are normally primarily egg albumins in water, are a famous example of denaturing in proteins. Egg whites are clear and liquid right out of the eggs.As a result of denaturation, many of the weak connections or bonds (such as hydrogen bonds) that give proteins their highly organized structure in their native (natural) state are broken. Most denatured proteins are insoluble and have a looser, more erratic structure.When part of the hydrogen bonds in a protein are broken, the protein loses some of its natural structure and becomes denatured. When weak hydrogen bonds are subjected to an acid or too much heat, they will break (like citric acid from lemon juice).Denaturation is the process that results in a protein losing its structure. Denaturation is typically brought on by the protein being subjected to external stressors such solvents, inorganic salts, exposure to acids or bases, and heat.Acids hp in the digestion of proteins by ;

Molar solubility of Fe(oh)3 in a solution that is buffered at pH 2.50 is 2.0×10−3M.
What is solubility product constant?A salt compound will dissolve in the liquid water by forming an aqueous solution of its constituent ions. The saturated solution has compound dissociation reaction in a solubility equilibrium and we define this state using the compound's solubility product constant Ksp . This parameter will only change with solution temperature. In contrast, compound's molar solubility limit in the saturated solution can be manipulated in numerous other methods. One example involves trying to dissolve an acidic/basic salt compound in a solution that is buffered at certain pH. The pH will control compound's molar solubility because it affects the molarity of the acidic/basic constituent ion in the solution.
How can we solve it?Iron (III) hydroxide has following solubility equilibrium for its saturated solution with the given constant value:
Fe(OH)3(s)⇋Fe3+(a q)+3OH−(a q)
Ks p=6.3×10−38=[Fe3+][OH−]3

The ______________________ is used to detect an increase in ph from 4.4 to 6.0 as mixed acids are further catabolized to form the neutral product ________________.
As mixed acids continue to be catabolized to produce the neutral product, the methyl red test is used to gauge the pH shift from 4.4 to 6.0.
The pH scale is used to determine an aqueous solution's acidity or basicity. Historically, pH stood for "potential of hydrogen" (or "power of hydrogen"). In comparison to basic or alkaline solutions (solutions with higher concentrations of H+ ions), acidic solutions have lower pH values measured.
The hydrogen ion concentration in the solution is inversely proportional to the pH scale's logarithmic scale. The origin of the pH scale can be traced to a collection of standard solutions whose pH has been established by consensus on a global scale. Utilizing a concentration cell with transference, the primary pH standard values are computed by measuring the potential difference between a hydrogen electrode and a standard electrode, such as the silver chloride electrode.
Methyl red is a pH indicator with a pKa of 5.1; it is red at pH values below 4.4, yellow at pH values over 6.2, and orange at pH values in the middle. As potential boosters of the sonochemical annihilation of chlorinated hydrocarbon contaminants, murexide and methyl red are being studied.
