Answer:
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
Explanation:
A strong electrolyte is a substance that dissolves in water, dissociating in its ions, and making the solution an electric conductor. The conduction will happen because of the presence of the ions. The dissociation will be complete and irreversible.
The chromium (II) nitrate is formed by the cation chromium (II), Cr⁺², and the anion nitrate, NO₃⁻, so it is the compound Cr(NO₃)₂.
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
Neon is an element that has 10 electrons, 10 protons, and most of the time has 10 neutrons in each neon atom. Nitrogen is an element that has 7 electrons, 7 protons, and most often has 7 neutrons in each nitrogen atom. So the Bohr model of a neon atom would be slightly larger than a nitrogen atom.
Basically, electron donors are the elements that give up there electrons, so they will be oxidized. In the reaction, Zn(s) oxidizes into Zn^+2, so the 2 electrons are bing donated to the Cu^2+. Thus Zn(s) is the electron donor
Answer:
When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.
Explanation:
Due to the positive value of the change in temperature, this is an endothermic reaction.
Since the forward reaction is endothermic, increasing the temperature increases the equilibrium constant (k).
In an equilibrium system, the position of the equilibrium will move in a way to annul the change made to the system. An increase in temperature for an endothermic reaction would favour the reaction, leading to increase in amount of products and decrease in amount of reactants.
