Answer:

2H⁺ + 2e → H₂.

Zn → Zn²⁺ + 2e.

Explanation:

The reaction includes two half-reactions:

The reduction reaction:

2H⁺ + 2e → H₂.

2.0 moles of hydrogen ions is reduced by 2 electrons to produce 1.0 mole of hydrogen gas.

The oxidation reaction:

Zn → Zn²⁺ + 2e.

1.0 mole of Zn metal is oxidized to Zn²⁺ and releases 2 electrons.

The overall reaction will be:

Zn + 2H⁺ → Zn²⁺ + H₂.

D) the college students

Explanation:

In the experiment conducted by staffs of the nursing home, the group of college students that came for the experiment are the subjects of the experiment. A subject is a person that participates in a research.

In this research, the college students are the human participants in the experiment.
There must be a mutual agreement between the researcher and the subject because the subject is one that is being tested to see an outcome.
A subject can quit a research if he/she deems it fit at any time.

How many potassium atoms are in 250.0 grams of potassium?

loris [4]

Hi!

The correct option would be 3.85x10^(24)

To find the number of atoms in 250g of potassium, we need to first calculate the number of atoms in

1 mole of Potassium = 39g which contains 6.022x10^(23) atoms of K

(Avogadro's constant value for the amount of molecules/atoms in one mole of any substance)

Solution

So as 39g of Potassium contains 6.022x10^(23) K atoms

1g of Potassium would contain 6.022x10^(23) / 39 = 1.544 x10^(22) atoms

So 250g of Potassium would contain 1.544x10^(22) x 250 = 3.86x10^(24) atoms

What is the electron configuration for 08 16

Elis [28]

The electron configuration for Oxygen : [He] 2s²2p⁴

<h3>Further explanation</h3>

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d, and f. The maximum number of electrons for each sub-shell is

• s: 2 electrons

• p: 6 electrons

• d: 10 electrons and

• f: 14 electrons

Charging electrons in the sub-shell uses the following sequence:

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.

The element is Oxgen, with symbol O, and :

the atomic number=8=number of electron

the atomic mass=16

The electron configuration based on the number of electrons(for Oxygen=8), so the configuration :

$\tt _8^{16}O:1s^22s^22p^4$ or we can write with noble gas [He] 2s²2p⁴
