Clouds are made of water. When water evaporates it turns into clouds. So, I think the answer is EVAPORATED water.
Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.
<h3>What is Cation ? </h3>
Cations are positively charged ions. It forms when an element lose one or more electrons.
<h3>
What is Anion ? </h3>
Anions are negatively charged ions. It form when an element gains one or more electrons.
Symbol Cs⁺¹ SO₃⁻²
Valency +1 -2
Formula of the compound is Cs₂SO₃.
Thus from the above conclusion we can say that Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.

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:
A.
Explanation:
Adjust = Adapt if that makes sense.
