Answer:
Solution of pH 7 contains thousand times more hydrogen than the solution of pH 10.
Explanation:
pH of A substance is given by the negative of the logarithm of concentration of hydrogen ions. It is given by the equation
Here the initial pH is given as 7. We have to calculate the concentration of ions.
The final solution has a pH 10. We have to calculate the concentration of in this case
Next we have to calculate how many times more is the ion concentration in the solution of pH 7 when compared to the solution with pH 10.
Thus the concentration of ion in the solution of pH 7 is 1000 times more than the solution of pH 10.
A solution at pH 7 contains 1000 times more hydrogen ions than a solution at a pH of 10. This is due to the logarithmic nature of the pH scale where each unit difference equals a tenfold difference in hydrogen ion concentration.
The pH value of a solution is the negative logarithm base 10 of the concentration of Hydrogen ions in the solution. The difference in pH from 7 to 10 implies a ten-fold difference for each unit of pH, thus, a difference of three pH units indicates a difference of 103, or 1000 times in hydrogen ion concentration. Therefore, a solution at pH 7 contains 1000 times more hydrogen ions than a solution at a pH of 10.
As a side note, it is important to remember that a lower pH value indicates a higher acidity (more hydrogen ions) and a higher pH value indicates a lower acidity (fewer hydrogen ions).

contour farming:
Contour farming has been practiced for centuries in parts of the world where irrigation farming is important. Although in the United States the technique was first practiced at the turn of the 19th century, straight-line planting in rows parallel to field boundaries and regardless of slopes long remained the prevalent method. Efforts by the U.S. Soil Conservation Service to promote contouring in the 1930s as an essential part of erosion control eventually led to its widespread adoption.

The energy of the electrons passing along the electron transport chain is used to make ATP.
Electron Transport Chain:
It is group of protein that transport electrons trough them and utilize the energy to transfer protons (H+) across the plasma membrane.
Therefore, the energy of the electrons passing along the electron transport chain is used to make ATP.
