Answer:
1.445 x 10²³ atoms.
Explanation:
- It is known that 1.0 mole of any element contains Avogadro's no. (6.022 x 10²³) of atoms.
<u><em>Using cross multiplication:</em></u>
1 mol of Ag contains → 6.022 x 10²³ atoms.
∴ 0.24 mol of Ag contains → <em>??? atoms.</em>
∴ The no. of Ag atoms in 0.24 mol = (0.24 mol)(6.022 x 10²³ atoms)/(1 mol) = 1.445 x 10²³ atoms.
Answer:
Evaporation is great for separating a mixture (solution) of a soluble solid and a solvent. The process involves heating the solution until the solvent evaporates (turns into gas) leaving behind the solid residue. ... This method is best for separating a liquid from a solution.
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. ... Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate).
Explanation:
That's your answer.
It is likely to receive one electron from another element's atom during the creation of a bond, based on the electron configuration. The arrangement of electrons in energy levels surrounding an atomic nucleus is termed electronic configuration, or electronic structure.
Fluorine's electron configuration is
Because fluorine contains seven valence electrons, it is most likely to acquire one to create a 1-charged ion. To complete its octet, it will require one more electron. As a result, the oxidation number is 1, indicating that when fluorine interacts with another atom to form a more stable combination, it will acquire or share one electron. As a result, it is likely to acquire one electron from an atom of another element during the creation of a bond, based on the electron configuration.
