Answer:
<h2>4. Na+ diffusing toward the side of the membrane with Cl− and 50% less Na+.</h2>
Explanation:
Facilitated diffusion is a type of transport mechanism in which the special proteins are involved and play an important role in the transport of the atoms, ions or molecules. This mechanism is based on the electrochemical gradient differences. When this difference increase, then the transport of the sodium takes place because sodium ions are chemically attracted by chloride ions. In a facilitated diffusion process, no energy requirement takes place. This process occurs along the concentration gradient.
Weak bases are alkaline solution that does not get completely dissociated. The dissociation constant will be the ratio of the concentration of the products to the reactants.
<h3>What is a weak base ionization constant?</h3>
The weak base ionization constant is the equilibrium constant that is given as the division of the products of the ionization to the concentration of the reactants.
The reaction for HCO₃ is given as:
HCO₃⁻ + OH⁻ ⇄ CO₃²⁻ + H₂O
The value of Ka for the given reaction will be:
Ka = [CO₃²⁻][H₂O] ÷ [HCO₃⁻ ][OH⁻]
Therefore, the Ka of the weak carbonic acid is given as the ratio of the concentration of the products to the reactants.

Answer:
Molecules
Explanation:
If you had more than one atom chemically bonded together, then regardless of the types of atoms that are bonded, you're going to have a molecule regardless.
This is because copper is a transition metals.
Transition metals don't have a definite charge, you can see this on the periodic table. However, Alkali Earth, Alkali, Metalloids, Non-metals, Halogens, Noble Gases, etc, all have a specified charge.
Although, there are exceptions: Zinc, Gold, and Cadmium.
Aluminum is a poor metal, but it has it's own charge (3+).
Therefore, Copper has roman numerals due to the fact that it's a transition metal and Aluminum is a poor metal.
Hope this helps!
