What is a best explanation for different metals having various colors? es
A)
The spectrum of lines will be produced, some of which will be in the
visible part of the spectrum. The color you see will be the highest energy
observed.
B)
The spectrum of lines will be produced, all of which will be in the visible
part of the spectrum. The color you see will be the most common color in
the spectrum.
The spectrum of lines will be produced, all of which will be in the visible
part of the spectrum. The color you see will be a combination of all these
individual colors.
D)
The spectrum of lines will be produced, some of which will be in the
visible part of the spectrum. The color you see will be a combination of all
these individual colors.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
