Answer:
Explanation:
because in air the particles are moving very fast and jar of coffee has hot particles which kinetic energy is also more so that's why it's particles move faster and gets mixed with air and smell is coming from far away
Answer:
5.12 molecules of Ag₂S could be produced from 10 molecules of silver.
Explanation:
Given data:
Molecules of Ag = 10 molecules
Molecules of Ag₂S = ?
Solution:
First of all we will convert the number of molecules into gram.
10/ 6.022 ×10²³ = 1.7 × 10⁻²³ mol
Mass of Ag:
Number of moles = mass/ molar mass
Mass = Number of moles × molar mass
Mass = 1.7 × 10⁻²³ mol × 107.9 g/mol
Mass = 183.43 × 10⁻²³ g
Chemical equation:
2Ag + H₂S → Ag₂S + H₂
Now we will compare the moles of silver with Ag₂S from balanced chemical equation.
Ag : Ag₂S
2 : 1
1.7 × 10⁻²³ : 1/2 ×1.7 × 10⁻²³ = 0.85 × 10⁻²³ mol
Molecules of Ag₂S:
0.85 × 10⁻²³ × 6.022 ×10²³ = 5.12 molecules
Among the given options, Option (D) that is O,
will have the same number of protons. Hence option (D) is correct.
<h3>What are
protons ?</h3>
A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron.
In option (D), All the three species (O,
) bears 8 protons but the number of electrons varies.
In any Ion, there will be no change in number of protons among the same atoms but number of electrons varies.
Therefore, Option (D) has same atoms but different ions.
Hence, it has same number of protons. Thus the correct answer is option (D)

Answer:
low-spin complexes contain the maximum number of unpaired electrons.
Explanation:
In the crystal field theory, the magnitude of crystal field splitting and the pairing energy determines whether a complex will be low spin or high spin.
Low spin complexes often have greater magnitude of crystal field splitting energy than low spin complexes.
High spin complexes have maximum number of unpaired electrons(most of the electrons are unpaired) while low spin complexes have a minimum number of unpaired electrons in a complex(most of the electrons are paired).
Answer:
2.11 x 10²⁴ molecules.
Explanation:
- <em>It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).</em>
<em><u>Using cross multiplication:</u></em>
1.0 mole of H₂O contains → 6.022 x 10²³ molecules.
3.5 mole of H₂O contains → ??? molecules.
∴ 3.5 mole of H₂O contain = (3.5 mol)(6.022 x 10²³) = 2.11 x 10²⁴ molecules.
