Answer:
pH 4
Explanation:
Firstly, we define pH as the negative logarithm to base 10 of the concentration of hydrogen ions.
Mathematically, we express this as:
pH = -log[H+]
Now let’s us calculate the concentration of hydrogen in each of the pH
For pH 4, we have:
4 = -log[H+]
[H+] = -Antilog(4)
[H+] = 0.0001M
For pH 5,
[H+] = -Antilog(5)
[H+] = 0.00001M
We can see that 0.0001 is greater than 0.00001 and thus it has a greater concentration of hydrogen ions
Your answer is C. Sublimation :)(
Answer: Option B
Explanation:
Cell membrane can be defined as the outermost covering of the cell which allows the movement of particles across membrane. The particles are allowed to move from inside of the cell to the outside of the cell and from outside to inside of the cell.
This kind of a membrane is known as selectively permeable which allows the movement of certain molecules only.
hence, the correct answer is option B
Answer:
An Extraneous root
Explanation:
A(n) Extraneous root is a root that is introduced into an equation in the process of solving the equation but does not satisfy the conditions of the original equation.
