E) Mr. Balmer never got the Nobel prize, which made everyone in the field of spectroscopy so angry, they worked extra hard.

the most appropriate will be

C) When electrons change levels to produce the Balmer series, the emitted light is in the visible part of the spectrum

Balmer series of hydrogen lines. These lines are emitted when the electron in the hydrogen atom moves from the orbital n = 3 or greater shell down to the n = 2 shell/orbit. ... Energy is emitted from the atom when the electron leaps from one orbit to another closer to the nucleus.

Wiens law has to do with the radiation  of a black body.

Antimony pentafluoride has a formula of SbF5. What is the percent composition of Sb in this molecule
Akimi4 [234]

Answer:

56.17% is percent composition of Sb in the molecule

Explanation:

Percent composition is the percent in mass of each element present in a particular molecule.

In SbF₅, there is 1 mole of Antimony -Molar mass: 121.76g- per 5 moles of fluorine -Molar mass: 19g/mol-. In a basis of 1 mole, the mass of Sb and F is:

<em>Mass Sb:</em>

1mol * (121.76g/mol) = 121.76g

<em>Mass F:</em>

1 mol SbF₅ = 5 moles F * (19g / mol) = 95g

<em>Total mass:</em>

121.76g + 95g = 216.76g

And percent composition of Sb:

121.76g / 216.76g * 100 =

<h3>56.17% is percent composition of Sb in the molecule</h3>

Fluorine (F) has seven electrons in its outermost shell. Fluorine _____.
Ira Lisetskai [31]
2. F is non-metal, because it has seven electrons (more that 3)
3.It <span>fills its shell by gaining one electron, because it is easier to gain 1 e⁻ than to loose 7 e⁻.
4. It </span><span>becomes a negatively charged ion, because atom of F is neutral, it has "0" charge, and it takes one negatively charged electron(-1). (0 +(-1)= -1)</span>

Why is it necessary to add concentrated HCl, then water, rather than a solution of HCl to the eudiometer tube
Dmitry_Shevchenko [17]
The reaction between concentrated acid and water can release a lot of heat. If a little water is added to a larger amount of acid, the heat can cause the small amount of water to boil very rapidly which then spatters some acid. ... It is recommended that acid should be added to water and not water to acid.
