Answer:
Explanation:
The equilibrium constant for a given reversible aqueous reaction is defined by the product ratio of the concentrations between the products and reactants:
aA + bB ⇄ cC + dD
<em>where K: is the equilibrium constant, [C] and [D]: are the product concentrations, [A] and [B]: are the reactant concentrations and a,b,c,d: are the stoichiometric coefficients from the reaction. </em>
Therefore, based on the definition the equilibrium constant of our reaction is:
2CrO₄²⁻(aq) + 2H₃O⁺(aq) ⇄ Cr₂O₇²⁻(aq) + 3H₂O(l)
Generally, the water concentration is omitted from the expressions.
I hope it helps you!
Answer is: chemical elements<span> in </span>group 15<span> of the </span>periodic table have <span>neutral atom with a valence electron configuration of ns</span>²<span>np</span>³<span>.
</span>Nitrogen: [He] 2s² 2p³.
Phosphorus: [Ne] 3s² 3p³.
Arsenic: <span>[Ar] 3d</span>¹⁰ 4s² 4p³.
Bismuth: <span>[Xe] 4f</span>¹⁴ 5d¹⁰ 6s² 6p³.
Moscovium: predicted [Rn] 5f¹⁴<span> 6d</span>¹⁰<span> 7s</span>² 7p³.
These elements have 5 valence electrons.
All atoms are made up of different amounts of atoms. Ex: some may have two some may have 3
It’s Ca3N2 I hope this is helpful
