The tricky bit with color is that we don't see frequency along a single band. Rather, there are 3 bands (RGB) that get added together (plus a fourth input for brightness as well as many sub-processes that deal with textures and patterns). Light of a single frequency excites one band a lot, the other a little, and the last almost none. This sum is what we percieve. Some people are missing a band (usually blue or green) causing color blindness. Either way, a rainbow looks continuous but by mixing light there are many ways to generate the same color. It's all a bit dirty.

The other stuff seems to confuse the idea of error, eg you seem to think "quantity + error = quality". But in such cases, error is usually known (and compensated for) turning the equation into the sum of two 'knowns', leading to another 'known'.

Pls explain ionization energy​
Oliga [24]

Answer:the energy required by an atom to lose or gain electron (e-) to be able to form ions.either cation or anion.

Explanation:

to lose or gain e- an atom has to donate or receive e- to to this it requires the more easily it can lose an electron the more electro positive it is and the more easily it gains electron the more electro negative it is.

Consider the following isotopic abundance data for argon (Ar) and silicon (Si):
pshichka [43]

Answer:

Explanation:

Molar mass of Argon

= 35.96755 x .00337 + 37.96272 x .00063 + 39.96240 x .99600

= .12121 + .0239165 + 39.80255

= 39.95

Molar mass of silicon

27.97693 x .9223 + 28.97649 x .0467 + 29.97376 x .0310

= 25.803 + 1.35320 + .929

= 28.08

b )

No of atoms of Si  in 78.2 g = 78.2 x 6.02 x 10²³ / 28.08

= 16.76 x 10²³ .

c )

42 Ar / 40 Ar = 1.05006

42 Ar / 39.95 = 1.05006

42Ar = 41.95

2 )

C₁₆H₁₅F₂N₃O₄S

Mol weight = 16 x 12 + 1 x 15 + 2 x 19 + 3 x 14 + 4 x 16 + 32

= 192 + 15 + 38 + 42 + 64+ 32

= 383

No of molecules = .078 x 6.02 x 10²³ / 383

= 1.226 x 10²⁰ molecules .
