SeO2(s)+O2(g)+H2O(l)→H2SeO4(aq) Count the number of each atom on each side of the equation to determine whether the equation is balanced: Reactants: 1 Se atom, 5 O atoms, 2 H atoms. Products: 1 Se atom, 4 O atoms, 2 H atoms . Balance the number of oxygen atoms by adding a coefficient of 2 to aqueous selenic acid on the products' side of the ...

2018年12月5日 · Re: H2SeO4 Structure Post by Raj_Bains_2C » Wed Dec 05, 2018 11:43 pm I am not sure what the reason is for this, but I just know that the whole lewis structure is more stable if the H is attached to the O instead of the Se.

HSeO4− or HTeO4− or HTeO4−, because H2TeO4 is the weaker acid HSeO4−, because H2SeO4 is the weaker acid HSeO4−, because H2SeO4 is the stronger acid HTeO4−, because H2TeO4 is the stronger acid

H2SeO4 • In this molecule we have, two OH attached to central atom Se with single bond and two O at...

Question: Selenic acid, H2SeO4, is produced from elemental selenium in a two-stage reaction. First the selenium is oxidized to selenous acid by nitric acid. Then the selenous acid is oxidized by potassium permanganate to selenic acid.

2024年1月22日 · (a) H2SeO4 is the stronger acid in the pair H2SeO3 or H2SeO4. This is because it has more oxygen atoms which increases its electronegativity, making it more acidic. (b) H3PO4 is the stronger acid in the pair H3PO4 or H3AsO4. This is because it has more electronegative atoms (oxygen) bonded to the central atom, making it more acidic.

Like sulfuric acid, selenic acid (H2SeO4) is a diprotic acid that has a very large value of Ka1. Part A: Calculate the pH in 0.20 M H2SeO4 (Ka2=1.2×10−2). Answer found to be 0.68 Part B Calculate the concentration of H3O+. Part C Calculate the concentration of H2SeO4. Part D Calculate the concentration of HSeO−4.

Question: Problem 14.76 Part A Write balanced net ionic equation for the first stage of dissociation of the diprotic acid H2SeO4. Express your answer as a chemical equation. Identify all of the phases in your answer. Part C Write balanced net ionic equation for the second stage of dissociation of the diprotic acid H2SeO4.

Which of the following acids will be the strongest? GIVE AN EXPLANATION. H2SO3, H2SO4, HSO3-, H2SeO4, HSO4-
