Infrared is the region in the electromagnetic spectrum to which the maximum intensity of the earth's outgoing radiation.
To explain why it falls on the infrared region of the electromagnetic spectrum, it must be noted that solar radiation powers the climate system of the earth. Some of these are reflected by the Earth and its atmosphere. Now, the earth does not contain the sun's energy from within its vicinity. It gives off infrared radiation through its surface to maintain its internal temperature.
Answer:
No. Au⁺ has a complete 5d sublevel.
Explanation:
The color of the transition metal/ion arises due to d-d transition which means that when energy of certain frequency is passed though the solution of the transition metal ions, the electrons of the d orbital gain some energy and goes to higher energy level. The energy absorbed lies in the visible region and thus they are appeared colored.
The electronic configuration of Au is:
1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶4f¹⁴5d¹⁰6s¹
If the gold atom looses one electron, then the electronic configuration is:
1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶4f¹⁴5d¹⁰
<u>Hence, in the configuration, the 5d orbital is full filled and there is no scope for d-d transition. </u>
<u>Thus, there will Au⁺ will not be colored.</u>
Answer:
Explanation:
Hey i was wondering if you had the answers for that
There are at least two ways to look at this.
Method One :
The Zn in Zinc Cyanide belongs to valency two while the CN radical
belongs to valency one. As a result, you would need two CN radicals
to bond with the Zn to make it a stable compound. Hence the formula
being Zn(CN)₂
Method Two :
Since the mole of zinc is 4.7 mol and that of CN is 9.5 mol then that
means that there is twice as much moles of CN as there is Zinc
4.7 mol × 2 = 9. 4 mol. Thus the formula would be Zn(CN)₂
