The equation is not a transmutation because there is conservation of the number of atoms as well as the number of nucleons; option C.
<h3>What is transmutation?</h3>
Transmutation refers to the artificial synthesis of new elements by a nuclear reaction of the original element and nuclear particles.
In transmutation, a new element is formed and the atomic number changes.
Based on the above, it can be concluded that the given equation is not a transmutation because there is no change in atomic and nucleon number.

Answer:
∆S = ∆H / T = 17.2 kJ/mol (298 K)
∆S = 0.0577 kJ/mol K
∆S = 0.0577 kJ/mol K x 1.41 moles = 0.0814 kJ/K = 81.4 J/K
1.41 mol x 17.2 kJ/mol = 24.25 kJ
∆S = 24.25 kJ / 298 K = 0.0814 kJ/K = 81.4 J/K
Explanation:
<u>Answer:</u>
concentration of H ions = 0.0001 M
<u>Explanation:</u>
Base 10 logarithm of the H+ concentration when multiplied by -1 is equal to the pH value of a solution. By reversing this formula, we can find the concentration of the H+ in the solution:
pH = ㏒
or = concentration of H+
We know that, pH of the solution is 4.0,
so =
Therefore, the concentration of Hydrogen ions in a solution of pH = 4 is 0.0001 M.
A chemical change is characterized of the formation of new substances or a chemical reaction. There are a number of observations that we can see if this type of change happens. One would be the formation of gas bubbles, this indicates that one of the products is a gas. Another observation would be a formation of a precipitate in the solution, it would indicate that the new solid formed is not soluble in the solution. A permanent color change in the solution would also indicate a chemical change because it may be that the new substance that is formed has its own distinct color when in solution.
