Explanation:

Atoms that share electrons with each other tend to form a covalent bond. Whereas atoms that show transfer of electrons from one atom to another tend to form an ionic bond.

Sodium has atomic number 11 and oxygen has atomic number 8. In order to become stabilized, sodium needs to lose one electron whereas oxygen needs to gain two electrons. So, two sodium atoms will combine with one atom of oxygen. This will form an ionic bond between sodium and oxygen atom.

Carbon has atomic number 4 and fluorine has atomic number 9. Therefore, both of them will share electrons in order to become stabilized. Thus, they will form a covalent bond.

Oxygen atom has atomic number 8 and hydrogen has atomic number 1. Therefore, both of them will share electrons but due to difference in electronegativity of both hydrogen and oxygen they will result in the formation of a polar covalent bond.

Aluminium has atomic number 13 and chlorine has atomic number 17. So, aluminium will donate or transfer its valence electron to chlorine atom. Therefore, it will also form an ionic bond.

Thus, we can conclude that carbon (C) and fluorine (F) and oxygen (O) and hydrogen (H) are the combination(s) that would result in sharing of electrons.

ad-work [718]

Answer:

The allowable values for the principle quantum number (n) are integers greater than zero.

The allowable values for the angular momentum quantum number (l) are integers from 0 to n-1.

The allowable values for the magnetic quantum number (ml) are integers from -l to l.

The allowable values for the spin quantum number (ms) are -1/2 and 1/2.

Explanation:

<em>Identify allowable combinations of quantum numbers for an electron. Select all that apply.</em>

  • <em>The allowable values for the principle quantum number (n) are integers greater than zero. </em>TRUE. The principal quantum number (n) represents the level of energy in which an electron is and can take positive integer values.
  • <em>The allowable values for the angular momentum quantum number (l) are integers from 0 to n-1.</em> TRUE. The angular quantum number (l) represents the sublevel of energy and the kind of orbital an electron is in and can take integer values from 0 to n-1. For instance, if n = 1, l can take the value "0", which represents the sublevel and orbital "s".
  • <em>The allowable values for the magnetic quantum number (ml) are integers from -l to l.</em> TRUE. The magnetic quantum number (ml) represents the orientation of an orbital in space and can take integers values from -l to +l. For instance, if l = 1 (p orbital), ml can take the values -1, 0 and 1, which refer to orbitals px, py and pz.
  • <em>The allowable values for the spin quantum number (ms) are -1/2 and 1/2. </em>TRUE. The spin quantum number (ms) represents the spin of the electron and can take values -1/2 and +1/2.

Calculate the mass percent for all components in a solution containing the following. 0.350 Kg of water, 5.4 moles of ammonia an
Alina [70]

Answer:

  • % Water = 54.96%
  • % Ammonia = 0.14%
  • % Cobalt (II) Nitrate = 30.62%

Explanation:

To calculate mass percent, first we need to <u>calculate the total mass of the mixture</u>:

  • Mass Water ⇒ 0.350 kg Water = 350 g water
  • Mass Ammonia⇒We use ammonia's molar mass⇒5.4 mol * 17 g/mol =  91.8 g
  • Mass cobalt (II) nitrate ⇒ 195.0 g

Total Mass = Mass Water + Mass Ammonia + Mass Cobalt Nitrate

  • Total Mass = 350 g+ 91.8 g+ 195 g = 636.8 g

To calculate each component's mass percent, we divide its mass by the total mass and multiply by 100:

  • % Water ⇒ 350/636.8 * 100% = 54.96%
  • % Ammonia ⇒ 91.8/636.8 * 100% = 0.14%
  • % Cobalt (II) Nitrate ⇒ 195/636.8 * 100% = 30.62%

A sample of aspirin weighing 5.945 g became contaminated with 2.134 g of sodium sulfate. The resulting
ira [324]

Answer:

The correct answer to the following question will be "62.9 %".

Explanation:

The given values are:

The aspirin's initial amount = 5.945 g.

and is polluted containing 2,134 g of sodium sulfate.

After extraction we provided 3,739 g of pure aspirin.

Now,

Percentage \ of \ recovery \ aspirin =\frac{Aspirin \ amount \ isolated \ after \ extraction}{initial \ amount \ of \ aspirin}\times 100

On putting the values in the above formula, we get

⇒                                                    =\frac{3.739}{5.945}\times 100

⇒                                                    =62.9 \ percent

Note: percent = %
