Answer:

2.18x10^-9 M

Explanation:

From the question given,

Hydrogen ion concentration, [H+] = 4.59x10^-6 M

Hydroxide ion, [OH-] =?

The hydroxide ion concentration, [OH-] in the solution can be obtained as follow:

[H+] x [OH-] = 1x10^-14

4.59x10^-6 x [OH-] = 1x10^-14

Divide both side by 4.59x10^-6

[OH-] = 1x10^-14 / 4.59x10^-6

[OH-] = 2.18x10^-9 M

Consider the atom with the chemical symbol Ru.

Vinil7 [7]

Answer: 97

Explanation:

The element Ru is Ruthenium which has 44 protons.

In this case, our atom is an isotope with 53 neutrons.

With this information, we can use the mass number formula to find this atom's mass number.

mass number = protons + neutrons

mass number = 44 protons + 53 neutrons

mass number = 97

Imagine a small synthetic vesicle made from pure phospholipids enclosing an interior lumen containing 1 mM glucose and 1 mM sodi

Alexeev081 [22]

Answer:

C. H2O diffuses in.

Explanation:

The phospholipids-made synthetic vesicle in this case will act like a semi-permeable membrane while the solution in the interior lumen will be hypertonic to the surrounding pure water.

Hence, water molecules will diffuse into the lumen through the semi-permeable membrane because of the osmotic gradient that exist between the internal and the surrounding solution of the vesicle.

A carpenter uses sandpaper on a piece of wood. Before, the wood felt rough. After, the wood felt smooth. Did the friction betwee

frosja888 [35]

Answer:

Friction between the hand and the wood decreased.

Explanation:

The texture of the wood went from rough → smooth! This means friction between the hand and the wood was notably decreased.

According to this prompt, the carpenter used sandpaper against the wood. Sandpaper just so happens to be a very abrasive substance. The sandpaper polished and leveled out the wood which wore all the jutting bits away.- overall, making it much smoother and more pleasant to touch!

Hope I was of assistance! Have a nice day and Spread the Love! <3
