When a nonmetal oxide reacts with water, it forms an oxoacid with the same oxidation number as the nonmetal. Give the name and f
vaieri [72.5K]

Addition of chlorine to water gives both hydrochloric acid (HCl) and hypochlorous acid (HClO)

What are Transition metal oxides ?

Transition metal oxides (TMOs) are another class of nanomaterials, frequently used as anode in alkaline batteries due to their distinctive properties such as abundant active sites, short diffusion pathways, low preparation cost, high theoretical capacity and distinct reaction mechanism.

Cl2 + H2O ⇌ HClO + HCl

Cl2 + 4 OH− ⇌ 2 ClO− + 2 H2O + 2 e−

Cl2 + 2 e− ⇌ 2 Cl−

The acid can also be prepared by dissolving dichlorine monoxide in water; under standard aqueous conditions, anhydrous hypochlorous acid is currently impossible to prepare due to the readily reversible equilibrium between it and its anhydride.

2 HClO ⇌ Cl2O + H2O      K (at 0 °C) = 3.55×10−3 dm3 mol−1

The presence of light or transition metal oxides of copper, nickel, or cobalt accelerates the exothermic decomposition into hydrochloric acid and oxygen

2 Cl2 + 2 H2O → 4 HCl + O2

Which of the following statements is TRUE?
borishaifa [10]

Answer:

Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction:

Explanation:

Reaction quotient is the ratio of product of concentrations of products to product of concentrations of reactants at any time.

The same ratio at equilibrium (when rate of forward reaction becomes equal to rate of backward reaction) is equilibrium constant.

when Q < Kc, a forward reaction is favored.

When when Q > Kc, a backward or reverse reaction is favored

So the first statement that

a) A reaction quotient (Q) larger than the equilibrium constant (K) means that the reaction will favor the production of more products: false

b) No the rate of forward and backward reaction are equal.

c) c. Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction: True

d) Dynamic equilibrium indicates that the amount of reactants and products are equal: This could be static equilibrium but not dynamic.
