model an atom as an electron in a rigid box of length 0.100 nm, roughly twice the bohr radius. what are the four lowest energy levels of the electron?

Answers

Answer 1

The least energetic electrons are those in energy level I, also known as energy level K.Higher level electrons have more energy as you move away from the nucleus, and this energy increase is fixed and discrete.

What are the four main levels of energy?

Sharp, Principle, Diffuse, and F are the four you need to be aware of (fine or fundamental).So, s, p, d, & f.Only that many sublevels are contained in the Principal Energy Level (the number).

Where is the place with the least energy?

A 1s sublevel, which has a single orbital, is always the sublevel with the lowest energy.In its ground state, the hydrogen atom's lone electron will be located in the 1s orbital.As we move on to atoms containing multiple electrons, those additional electrons are added to the subsequent lowest sublevel, such as 2s, 2p, 3s, and so forth.

What is calcium carbonate?

Calcium carbonate is commonly called limestone. Limestone is mineral deposit found in many living and nonliving things. Rocks and shells of some organisms are major sources of calcium carbonate.

Calcium carbonate can be prepared by passing carbon dioxide through quicklime or calcium oxide CaO. Calcium carbonate will precipitate in a milky solution.

Limestone can also be prepared by the reaction of calcium hydroxide or soda lime with carbon dioxide. Each reacts in one mole and gives one mole of each product as written in the balanced reaction.

16. the electron configuration of nitrogen is how many more electrons does nitrogen need to satisfy the octet rule?

Answers

3 On the periodic table, column 5 contains nitrogen, denoted by the letter N.Its valence electron count is 5.To obtain an octet, three linkages must be created.The straightforward formula is 5 + 3 = 8.

The octet law applies to nitrogen, right?

The second row of the p-block area includes fluorine, oxygen, nitrogen, and carbon.When they combine, these elements closely adhere to the octet rule.In order to complete their octet, for instance, these elements combine with hydrogen to make two to four bonds.

For nitrogen to have a complete valence, how many additional electrons are required?

Two nitrogen atoms would have a total of 10 valence electrons if the entire number of valence electrons in nitrogen, which is five, were to be doubled.A triple bond is necessary for the octet since it needs 8 total electrons for an atom to have a full valence shell.

In comparison to the green substance, the attraction between the molecules in the pink substance is thought to be less. It moves apart from one another and changes from liquid to gas.

If the volume is decreased to 2.6 L and pressure is decreased to 3.2 atm, then temperature become 156.98K.

This problem can be solved by using the concept of Ideal gas equation.

What ia ideal gas equation?

The equation of ideal gas can be expressed as

PV = nRT

where,

P is the pressure of the gas

V is the volume taken

n is the number of moles of the gas

R is the gas constant = 6.314 J/ mol K

T is the temperature

Now from given data, we have the values of

V = 3.2 L

P = 5.5 atm

T = 53°C = 273 + 53 = 326 K

By substituting all the values, we get the value of n

3.2 × 5.5 = n × 6.314 × 326

17.6 = n × 2058.36

n = 17.6 / 2058.36

n = 0.0085 mol

Now, we have to find the temperature

n = 0.0085 mol

V = 2.6 L

P = 3.2 atm

By substituting all the values, we get

3.2 × 2.6 = 0.0085 × 6.314 × T

8.32 = 0.053 T

T = 8.32/ 0.053

T = 156.98 K

Thus, we concluded that if the volume is decreased to 2.6 L and pressure is decreased to 3.2 atm, then temperature become 156.98K.

Calcium Carbonate:

Calcium carbonate is a compound with the chemical formula CaCO3. It is a common substance found in rocks such as calcite and aragonite (primarily limestone, a type of sedimentary rock composed primarily of calcite) and is a major component of eggshells, snail shells, seashells and pearls. A substance containing a lot of calcium carbonate or a substance similar to calcium carbonate is called calcareous. Calcium carbonate is the active ingredient in agricultural lime and is formed when calcium ions in hard water react with carbonate ions to form scale deposits.

Now,

Since the CO₂ produced in this reaction must escape from the interior of the Caco₃ particles, the decrease at any temperature of the reaction speed is determined. This is determined by the size of the solid calcium carbonate particles and the partial pressure of CO₂ surrounding the particles.

Answers

The amount of CO that would be required to generate 635 g of CO₂ will be 404.14 g.

What is stoichiometric co-efficient?

To balance the amount of each element on the reactant and product sides of the equation, the stoichiometric coefficient is the number placed in front of the atoms, ions, and molecules in a chemical process.

Usually, it is positive for products and negative for reactants. Stoichiometric coefficients define the stoichiometry of a chemical reaction.

First, let us get the equation of the reaction:

The reaction becomes: Fe₂O₃ + 3CO → 2Fe + 3CO₂

From the equation, we can see that the mole ratio of CO to that of CO₂

= 3:3

= 1:1

Given that,

635 g of CO₂ is to be generated.

Mole of 635 g CO₂ = mass/molar mass = 635/44.01 = 14.43 moles

Thus, the equivalent mole of CO required will also be 14.43 moles.

Mass of 14.43 moles of CO = moles x molar mass

                                             = 14.43 x 28.01

                                             = 404.14 gm.
