Answer:
Explanation:
From the question we are told that
Light wavelength 
Light wavelength atom fall 
Photon wavelength 
Photon wavelength atom fall 
Generally the equation for the reciprocal of wavelength of emitted photon is is mathematically given by
Therefore for initial drop of 5th to 2nd
Therefore for initial drop of 6th to 2nd
Generally we subtract (5th to 2nd) from (6th to 2nd)
Therefore for 6th to 5th stage is mathematically given by
1 moL of a substance is equal to 6.02 x 10^23 atoms or particles , it true statement. This number is known as Avogadro number.
It most likely would be "miscible" because "soluble" refers to something being able to dissolve in water, "insoluble" is something not being able to dissolve or mix such as oil and water and immiscible is something not being able to mix without forming layers.
Answer is: Miscible.
Answer:
12 moles of F₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
N₂ + 3F₂ —> 2NF₃
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Finally, we shall determine the number of mole of F₂ needed to produce 8 moles of NF₃. This can be obtained as illustrated below:
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Therefore, Xmol of F₂ will react to produce 8 moles of NF₃ i.e
Xmol of F₂ = (3 × 8)/2
Xmol of F₂ = 12 moles
Thus, 12 moles of F₂ is needed for the reaction.
