Answer: -
9270 grams
Explanation: -
Number of molecules of C₆H₁₂O₆ = 3.25 x 10 ²⁶
According to Avogadro's law,
6.02 x 10 ²³ molecules of C₆H₁₂O₆ are present in 1 mole of C₆H₁₂O₆
3.25 x 10 ²⁶ molecules of C₆H₁₂O₆ are present in of C₆H₁₂O₆
= 54 mol of C₆H₁₂O₆
Molar mass of C₆H₁₂O₆ = 12 x 6 + 1 x 12 + 16 x 6 = 180g /mol
Mass of C₆H₁₂O₆ = 54 mol x 180g /mol
= 9270 g
This answer is true because it's t same amount
An ionic bond occurs when an atom transfers or takes Electrons from another atom.
10.2.5 mg/kg I think this was a confusing question
Answer:
The move from Level n=3 to Level n=2 has the long wavelength.
Explanation:
First, due to the selection rules, only transitions between adjacent levels are allowed, thus, only a transition between Level n=3 to Level n=2 or Level n=5 to Level n=4 are allowed. The two first options are wrong.
Second, analyzing the transition between Level n=3 to Level n=2 and the transition between Level n=5 to Level n=4 it is necessary to think in terms of the equation of the difference of energy for these type of transitions:
Δ (1)
The difference in energy (ΔE) is directly proportional to the quadratic difference between the 'n' levels of transition. Therefore, If the transition occurs between smaller 'n' levels the difference of energy will be smaller too.
Also, the energy (ΔE) is inversely proportional to the wavelength (λ) so a smaller energy means a larger wavelength.
ΔE = c / λ (2)
Hence, the move from Level n=3 to Level n=2 has a long wavelength.
In order to calculate this wavelength is necessary to replace the data on equation (1) and (2).
