The ____ contains the highest concentration of ozone.a. troposphere
c. stratosphere
b. mesosphere
d. exosphere

Moving electrons create a magnetic field. The answer is letter B. This is because a charged particle moving without acceleration produces an electric field or magnetic field. It produces an electric field or magnetic field because it is charged.

Answer:

Its a

Explanation:

I got that answer on my own not from the Question ;)

Final answer:

The third energy level in an atom, as described by quantum mechanics, contains three sublevels: the s, p, and d sublevels.

Explanation:

In the field of chemistry, the term energy level refers to the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. Specifically, when we refer to the third energy level, we're talking about an energy state with the principal quantum number n=3.

For any energy level defined by the principal quantum number n, there are n sublevels. Therefore, in a third energy level (n=3), we have three sublevels. These would be the s, p, and d sublevels.

#SPJ6

Answer:

5.65 is the pH.

Explanation:

I am assuming that you are asking for confirmation on your answer. The answer is 5.65.

You would do:

[pOH] = -log[OH-]

          = -log[4.5*10^-9]

         equals about 8.3468

To find pH your would subtract the pOH from 14.

14-8.3468 = 5.65 << Rounded to match the answer choices.

Answer;

K+

Explanation;

-Noble gas configuration is the electron configuration equivalent to noble gases or group 8 elements. According to the octet rule an atom of an element gains or looses electrons to attain noble gases configuration which is the stable configuration, such that an atom has attained maximum number of electrons in the outermost energy level.

-For instance potassium is an alkali metal, consisting of one valence electron in the outermost energy level. For an atom of potassium to attain octet configuration or noble gases configuration it will have to loose one electron, thus forming a positively charged ion of potassium, K+.

Answer:

The net charge of 1.3 g nugget of pure gold after 1.68% of its electrons are removed is 559 C

Explanation:

When an atom gains electrons it becomes negatively charged. Conversely, when it looses electrons the atoms becomes positively charged thus

To solve this question, we rely on the relationship between the nmber of particles present in a given mass of an atom, Avogadro's number and number of moles, n

The given variables are

mass of pure gold nugget = 1.30 g

Quantity of electrons removed = 1.68% of electrons present in the gold sample

Molar mass of gold = 197 g/mol

Avogadro's number = 6.02 × 10²³ atoms/mole  

qc = one electron charge = -1.06 × 10⁻¹⁹ C/electron

Electrical charge of gold nugget = 0 C

Number of electrons in one gold atom = 79 electrons

Solving for the number of prticles or gold atoms in 1.3 grams of gold we get

n mass/(molar mass) = 1.3/197 moles of gold =  0.0066 moles

number of particles in 0.0066 moles of gold N = n× = 0.0066 × 6.02 × 10²³  = 3.97 × 10²¹ atoms

since 79 electrons are present per particle we have

3.97 × 10²¹ × 79 = 3.14 × 10²³ electrons

quantity of elecrtrons removed = 1.68% of  3.14 × 10²³ electrons =1.68/100 × 3.14 × 10²³ electrons = 0.0168 × 3.14 × 10²³ electrons = 5.3 × 10²¹ electrons

The net charge of 5.3 × 10²¹ electrons = 5.3 × 10²¹ electrons × -1.06 × 10⁻¹⁹ C/electron =

5.59 × 10² C = 559 C
