Solar radiation process explained

Chemistry
1 answer:
Slav-nsk [51]3 years ago
6 0

Answer:

Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy.  About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.

Answer:

A. 0.064mol

B. 0.85mol

C. 1500mL

Explanation:

A. Molarity = 0.33M

Volume = 195mL = 195/1000 = 0.195L

Mole =?

Molarity = mole /Volume

Mole = Molarity x Volume

Mole = 0.33 x 0.195

Mole = 0.064mol

B. Molarity = 1.7M

Volume = 500mL = 500/1000 = 0.5L

Mole =?

Molarity = mole /Volume

Mole = Molarity x Volume

Mole = 1.7 x 0.5

Mole = 0.85mol

C. C1 = 12M

V1 = 50mL

C2 = 0.4M

V2 =?

Using the dilution formula C1V1 = C2V2, we find the volume of the diluted solution as follows:

C1V1 = C2V2

12 x 50 = 0.4 x V2

Divide both side by 0.4

V2 = (12 x 50) /0.4

V2 = 1500mL

Part A Add single electrons and/or electron pairs as needed to complete the electron-dot symbol for astatine, At. To return the
mezya [45]

Answer:

7 valence electrons

Explanation:

Astatine has the atomic number 85. Thus, its electron configuration is:

[Xe] 4f¹⁴ 5d¹⁰ 6s² 6p⁵

As we can see, in the last level (6) it has 2 + 5 = 7 electrons, that is, astatine has 7 electrons in its valence shell. In the Lewis dot structure (attached) we write 3 pairs of electrons and 1 unpaired electron around the symbol of At.
