When an ion‑selective electrode for X+ was immersed in 0.0482 M XCl, the measured potential was 0.0460 V . What is the concentration of X+ when the potential is 0.0610 V ? Assume that the electrode follows the Nernst equation, the temperature is at 25 °C, and that the activity coefficient of X+ is 1.
Answers
Final answer:
To find the concentration of X+ at a potential of 0.0610V, use the Nernst equation which describes the electrochemical potential of a system. Given the initial concentration of X+ and its potential, rearrange the equation to solve for the concentration of X+ at the new potential.
Explanation:
The problem given can be solved using the Nernst equation, which relates the reduction potential of an electrochemicalreaction (half-cell or full cell reaction) to the standard electrode potential, temperature, and the activities of the chemical species undergoing the reduction.
The Nernst equation at 25 °C can be simplified as:
E = E° - (0.059/n) log [Cl^- /[X^+]
Where E is the electrode potential, E° is the standard electrode potential, n is the number of electron transferred and [Cl^- /[X^+] is the ratio of ion activities. Since the ion's activity coefficient is 1, we can treat [X^+] as the concentration of X^+.
If you apply this equation, using the given potentials and known initial concentration of X^+, you can solve for the concentration of X^+ when the potential is 0.0610V.

Final answer:
The concentration of X+ can be calculated using the Nernst equation by substituting the initial and final potentials. By solving the equation, you can find the concentration of X+.
Explanation:
The concentration of X+ can be calculated using the Nernst equation. The Nernst equation relates the potential of a cell to the concentration of the ions involved.
The Nernst equation is given by:
E = Eº - (0.0592/n)log(Q)
Where E is the potential, Eº is the standard electrode potential, n is the number of electrons transferred, and Q is the reaction quotient.
In this case, the initial potential is 0.0460 V and the final potential is 0.0610 V. By substituting these values into the Nernst equation, you can solve for the concentration of X+.

Answer:
So trees in temperate don't lose their leaves because the weather events aren't harsh enough.
Trees in tropical rainforest don't lose their leaves because they are a different type of tree known as evergreens that are green all year round.
Explanation:
Ok so first we'll define some things
Deciduous Trees= Trees that lose all of their leaves for part of the year.
Trees shed their leaves trees to try and survive harsh weather events.
Temperate deciduous trees lose their leaves in fall to better survive the winter conditions of extreme cold and reduced daylight.
Temperate rainforests = An area that doesn't experience extremely cold or extremely hot temperatures or what we would call harsh weather events.
Broad-leaved trees in tropical rainforests are known evergreen, they are known as this as they are green all year round.

The nuclear reactions involves the nuclei of the atoms, large amount of energy will be involved and some of the mass is converted into energy.
Explanation
Nuclear reactions are reactions which leads to change in the nuclei of the atoms.
The nuclear reaction occur between the nuclei of two atoms or between nuclei and other particles of two atoms.
The product formed will be different from the reactants.
The difference in the mass of the products and reactants are generally converted into energy.
In some nuclear reactions like nuclear fusion reaction, large amount of energy is required to collide the nuclei of two heavy elements to undergo nuclear chain reaction.
