The Lewis structure of selenic acid, H2SeO4, is as follows: H-O-S=O. Explanation: The Lewis structure of selenic acid, H2SeO4, can be determined by following these steps: Count the total number of valence electrons in the molecule. Hydrogen (H) contributes 1 valence electron, selenium (Se) contributes 6 valence electrons, and oxygen (O ...

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 ...

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.

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.

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.

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