A row of 100 million atoms of a single type would be only about 1 centimeter (cm) long. What occupies most of this space?

Ilia_Sergeevich [38]

Over 99% of the atom is empty space.

Explanation:

To give an analogy of an atom; If the whole atom was a large football stadium then the nucleus would be a soccer ball at the center of the pitch in the stadium, with electrons (that hold negligible mass) skimming about in the empty space. This center ball carried most of the mass of the atom. Therefore most matter that you see is actually and ironically empty space.

A Tomato Has A Proton Concentration Of 0.00006 M. How Would You Calculate The PH?

Debora [2.8K]

Answer:

Option b. is correct

Explanation:

If hydronium ion concentration $H_3O^+$ is given then pH is given by $-log[H_3O^+]$

The hydronium ion refers to the hydrogen ion in aqueous solution.

A Tomato has A Proton Concentration Of 0.00006 M

Here, 0.00006 is equal to 6 × $10^{-5}$

So,

pH is given by - log [6 × $10^{-5}$ ]

Option b. is correct
