Answer: Membrane Protiens
Explanation:
In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
2 AL and 6 HCL AND 2 ALCL3 and 3 H2
The pH of a buffer solution with acid that (PKA 6. 1) is exactly half as concentrated as its conjugate base is 6.4.
<h3>What is a buffer solution?</h3>
A buffer solution is a solution that has a maintained pH, not basic or not acidic. Its pH changes when acid or base is added to the solution.
We had to figure out the acid's concentration, which is exactly half that of its potential base.
We know that pH = pH_log
We have less than 6.1 pH so this is a conjugated base.
This will equal to 6.1 + log2 = 6.4
Thus, the pH of a buffer solution with acid is 6.4.

%
Explanation:
If we know the grams of a chemical compound in a specific reaction, it is possible to know the percentage of each atom that composes it.
For the Aluminum Oxide in this problem, we know its total weight and the grams of each component.
therefore we can determine the percentage ratio of its components through:
For Al
