A model represents a place thing or idea. A made is a model as it shows a place and represents the place it’s showing such as a globe
Explanation:
the pH of the solution defined as negatuve logarithm of ion concentration.
1. Hydrogen ion concentration when pH of the solution is 11.
..(1)
At pH = 11, the concentration of ions is .
2. Hydrogen ion concentration when the pH of the solution is 6.
..(2)
At pH = 6, the concentration of ions is .
3. On dividing (1) by (2).
The ratio of hydrogen ions in solution of pH equal to 11 to the solution of pH equal to 6 is .
4. Difference between the ions at both pH:
This means that Hydrogen ions in a solution at pH = 7 has ions fewer than in a solution at a pH = 6
Answer:
The partial pressure of helium gas in a gaseous mixture of helium and hydrogen is the pressure that the helium would exert in the absence of the hydrogen. equal to the total pressure divided by helium's molar mass. O equal to the total pressure divided by the number of helium atoms present.
