Answer:
A solution of CH3Cl will not conduct electricity
Explanation:
Ionic substances conduct electricity because the solution is composed of ions. Ions are charge carriers in a solution. When an ionic substance is dissolved in water, the substance dissociates into its component ions. The concentration and activity of these ions determines the conductivity of the solution.
However, molecular substances are not composed of ions. Since they are not composed of ions, they do not dissolve in water to yield ions. This implies that solutions of molecular substances are do not conduct electricity.
CH3Cl is a molecular substance. It is not composed of ions, hence its solution does not conduct electricity.
Answer:
Explanation:
Let us consider the reaction:
2 NO₂ + 1/2 O₂ ⇄ N₂O₅
The rate of formation of a substance is equal to the change in concentration of the product divided the change in time:
The rate of disappearance of a reactant is equal to to the change in concentration of the reactant divided the change in time, with a negative sign so that the rate is always a positive variable.
The rate of the reaction is equal to the rate of any substance divided its stoichiometric coefficient. In this way, we can relate these expressions:

Answer:
An element that is oxidized is a reducing agent, because the element loses electrons, and an element that is reduced is an oxidizing agent, because the element gains electrons.
