In the disproportionation reaction CI2 + H2Omc021-1.jpgHCIO + HCI, what describes the oxidation states of the substance Cl?
Sophie [7]
<span>Reaction: CI2 + H2O    ---->  HCIO + HCI

Oxidations states:

The oxitation state of Cl2 = 0, because the oxidation state of an atom alone or a molucule with one kind of atom is always 0.

The oxidation state of Cl in HClO is +1 because the oxidation state of H is + 1, the oxidation state of O is - 2, and the molecule is neutral, so  +1 + 1 - 2 = 0

The oxidation state of Cl in HCl is - 1, because the oxidation state of H is +1 and the molecule is neutral, so - 1 + 1 = 0.

Also, you shall remember that when an atom increases its oxidation state is is oxidized and when an atoms reduces its oxidations state it is reduced.

With that you conclude that the right option is the last statement: </span>Cl has an oxidation number of 0 in Cl2. It is then reduced to CI- with an oxidation number of –1 in HCl and is oxidized to Cl+ with an oxidation number +1 in HClO.

When a reaction mixture reaches chemical equilibrium, ____.
Vesnalui [34]

When a reaction mixture reaches chemical equilibrium, The forward, as well as reverse reactions, happen at the same rates.

The concentrations of reactants, as well as products, remain unchanged when chemical equilibrium would be reached. It's crucial to keep in mind that both forward but also reverse reactions continue to happen, but at an equal rate.

The system enters a state of dynamic equilibrium when both forward as well as reverse reactions happen at the same rate. Chemical equilibrium happens when all of the reaction's steps reach dynamic equilibrium, or when there gets the balance between the reagents as well as the products is reached.

Therefore, when a reaction mixture reaches chemical equilibrium, The forward, as well as reverse reactions, happen at the same rates.
