This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
The chemical formula for hydrogen selenide is H2Se. Hydrogen selenide is an inorganic molecule. This hydrogen chalcogenide is the simplest and most frequently seen form of selenium’s hydride. Under normal circumstances, H2Se is a gas that lacks color and is combustible. The safest exposure to this selenium compound is 0.05 parts per million for eight hours. It is the most hazardous selenium compound.
What do you call the compound h2so2?
Sulfoxylic acid, also known as hyposulfurous acid or sulfur dihydroxide, is an unstable oxoacid of sulfur that exists in an intermediate oxidation state between hydrogen sulfide and dithionous acid. Its chemical formula is H2SO2, and its other names include sulfoxylic acid and sulfur dihydroxide. It is made up of two hydroxy groups that are covalently bonded to a single sulfur atom.
How exactly does one go about writing out the formula for an acid?
You need to commit the following to memory:
- H2SO4 = Sulfuric acid.
- HNO3 = Nitric Acid.
- HC2H3O2 = acetic acid.
How would you write the chemical formula for orthophosphoric acid?
The chemical formula for orthophosphoric acid is H3PO4, and it is a type of phosphoric acid. It is a moderately strong acid that has three atoms of hydrogen, one atom of phosphorus, and four atoms of oxygen in its structure. -When burned with concentrated HNO3, red phosphorus produces orthophosphoric acid.

What exactly is the name of this substance?
Because both of the carbon atoms contributed to the synthesis of the carboxylic group, we call this type of acid a “dioic acid.” Thus, “ethanedioic acid” is the name given to the oxalic acid by the IUPAC.
How do you make 0.1 N oxalic acid?
Note: In the event that anhydrous oxalic acid (COOH) is accessible, the 0.1 N oxalic acid solution can be prepared by dissolving 4.5 grams of the acid in one liter of distilled water. Mix thoroughly after adding 13.16 grams of NaOH with 95% NaOH to one liter of distilled water.
What is the name of HOOC COOH in the Iupac system?
Oxalic acid is a type of alpha,omega-dicarboxylic acid that has ethane replaced by carboxyl groups at positions 1 and 2 in the chemical structure.
What exactly is the acid hyposulfuric?
an acid with the formula H2S2O6 that is only found in aqueous solutions of its salts and may be produced by reacting manganese dioxide with sulfur dioxide to produce it; this acid is also known as dithionic acid. Check out the Dithionic. Also see the entry for hyposulphuric.
What does it mean for pyrosulfuric acid to be anhydride?
The answer that you are looking for is (B)SO3.
Nitrous acid has a pKa of what exactly, can you tell me?
The pKa of nitrous acid was determined to be 3.16 at a temperature of 25 degrees Celsius. The enthalpy and entropy of the dissociation of nitrous acid were calculated based on measurements and came out to be 6.7 kJ mol(-1) and -38.4 J mol(-1) K(-1), respectively, between a temperature range of 25 degrees Celsius and 45 degrees Celsius.
How can you locate KB after starting with Ka?
To find the value of Kb, just solve the equation by dividing Kw by Ka. After doing this, you will have the equation Kb = Kw / Ka. In the equation, substitute the values that come from the problem. For instance, the value of Kb for the chloride ion is 1.0 x 10-14 divided by 1.0 x 10-6.
How do I determine pH?
You will need to know the concentration of the hydronium ion in an aqueous solution in moles per liter in order to determine the pH of the solution. After that, the pH is determined by applying the following formula: pH = – log [H3O+].
What is the origin of the name orthophosphoric acid?
Phosphoric acid does not strictly adhere to the definition of a strong acid; yet, a solution that is 85% concentrated can still cause significant irritation to the skin as well as damage to the eyes. It is possible to differentiate this particular acid from other “phosphoric acids,” such as pyrophosphoric acid, by referring to it by its more specific term, “orthophosphoric acid.”
The structure of h4p2o6 is as follows:
The chemical formula for hypophosphoric acid is H4P2O6, and the formal oxidation state of phosphorus in hypophosphoric acid is +4. Hypophosphoric acid is a type of mineral acid. It is found in the solid state as the dihydrate, which has the formula H4P2O62H2O. The phosphorus atoms that make up hypophosphoric acid are the same and are connected directly to one another via a PP bond.
What is the proper way to write carbonic acid?
The chemical formula for carbonic acid is H2CO3, and it is a substance made up of hydrogen, carbon, and oxygen.
In chemistry, what does the term “Hooc” mean?
The term “dicarboxylic acid” refers to a class of chemical compounds that each contain two functional groups of carboxylic acid… Oxalic acid (HOOCCOOH) is the simplest example of a dicarboxylic acid. Malonic acid (HOOCCH2COOH), succinic acid (HOOC(CH2)2COOH), and glutaric acid (HOOC(CH2)3COOH) are also dicarboxylic acids that play key roles in biochemistry.
