Which statement is true about the electrons that can be located together in an orbital?

Chemistry

The two electrons that share an orbital repel each other.

All electrons bear a negative charge. They are held in their orbits by the attractive force of charged protons. The farther away an orbital is to the atomic nucleus the easier it is to expunge an electron from this distant orbital shell.

Explanation:

Because electrons have the same negative charge, they repel each other especially when they occupy the same orbital shell in an atom. To reduce this repulsion, each of the electrons in the orbital shell (remember electrons occupy orbital shells of atoms in 2s) assumes an opposite quantum (M<em>s</em>) spin; one with  – ½ while the other + ½ .

A substance joined by this type of bond shares electrons
telo118 [61]

Answer: Covalent

Explanation:

A covalent compound is formed when an element shares its valence electron with another element. This compound is formed between two non metals. Example: HF

An ionic compound is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal. Example: NaCl

In a laboratory experiment, after purification, 4.567 g of nickel metal was obtained by a student. The student then calculated,
DaniilM [7]

Answer:

The yield of the purification is 79.7%

Explanation:

Hi there!

5.731 g nickel metal could be produced by the student if the yield of the purification would be 100%. Instead, 4.567 g was obtained. Then, the yield of the purification can be calculated as follows:

4.567 g Ni · (100% / 5.731 g) = 79.7%

The yield of the purification is 79.7%

Have a nice day!

Mole concept
natulia [17]

Answer: 50.9g of Fructose

Explanation:

No of moles =  Mass (g)  / Molar Mass (g/mol)

Moles = 0.283

Molar Mass of Fructose (C6H12O6) =  12 x 6 + 1 x 12 + 16 x 6 = 180g/mol

Mass  = ?

Make 'Mass' the subject of formular, we will have;

 Mass =  Molar Mass x  No of moles

           =  180g/mol  x  0.283

           =  50.9g of Fructose

Uranium can be isolated from its Ores by dissolving it as UO2(NO3)2, then separating If as solid UO2(C2O4).3H2O. Addition of 0.4
Arada [10]

Answer:

The limiting reactant is NaC₂O₄ and the yield of this reaction is 69.52%.

Explanation:

NaC₂O₄ + UO₂(NO₃)₂ + 3H₂O → UO₂(C₂O₄).3H₂O + 2NaNO₃

m (NaC₂O₄) = 0.4031 g  MW = 134 g/mol ∴ n = 3.0 mmol

m (UO₂(NO₃)₂) = 1.481 g MW = 396.05 g/mol ∴ n = 3.74 mmol

m (UO₂(C₂O₄).3H₂O) = 1.073 g MW = 412.094 g/mol ∴ n = 2.60 mmol

The limiting reactant is NaC₂O₄

The yield can be given by (2.60/3.74).100% = 69.52%
