The conclusion that was drawn from the results of the
gold foil experiment is that electrons in an atom are located in specific
shells. The answer is number 4. Also, he concluded that an atom was not an
empty space but rather, the electrons are scattered.
Answer:
0.027g
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 molecules.
From the above, it means that 1mole of SO3 also contains 6.02x10^23 molecules.
1mole of SO3 = 32 + (16x3) = 32 + 48 = 80g
If 1 mole (80g) of SO3 contains 6.02x10^23 molecules,
Then Xg of SO3 will contain 2x10^20 molecules i.e
Xg of SO3 = (80x2x10^20)/6.02x10^23 = 0.027g
This particular case in a species is called
<em>B) Carrying capacity</em>
... or when a population reaches its equilibrium.

Explanation:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34? On a calculator, calculate 10-8.34, or "inverse" log ( - 8.34).
