The name for the ionic compound Cs2S is Cesium sulfide.
Answer:
that the water is blue because of the way water absorbs light, the way particles in the water scatter light, and also because some of the blue light from the sky is reflected
<u>Answer:</u> D represents 222, E represents 86, F represents 234 and G represents 90.
<u>Explanation:</u>
The two given chemical reactions are a type of alpha decay processes. Alpha decay process is defined as the process, in which a heavier nuclei decays into lighter nuclei emitting alpha particle. The alpha particle released has a charge of +2 units. and is also known as a helium nucleus.
![_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_2^4\textrm{He}](https://tex.z-dn.net/?f=_Z%5EA%5Ctextrm%7BX%7D%5Crightarrow%20_%7BZ-2%7D%5E%7BA-4%7D%5Ctextrm%7BY%7D%2B_2%5E4%5Ctextrm%7BHe%7D)
The isotope formed has atomic mass reduced by 4 units and atomic number reduced by 2 units.
So, for the chemical equations:
1. ![_{226}^{86}\textrm{Ra}\rightarrow _{222}^{84}\textrm{Rn}+_2^4\textrm{He}](https://tex.z-dn.net/?f=_%7B226%7D%5E%7B86%7D%5Ctextrm%7BRa%7D%5Crightarrow%20_%7B222%7D%5E%7B84%7D%5Ctextrm%7BRn%7D%2B_2%5E4%5Ctextrm%7BHe%7D)
D represents 222, E represents 86.
2. ![_{238}^{92}\textrm{U}\rightarrow _{234}^{90}\textrm{Rn}+_2^4\textrm{He}](https://tex.z-dn.net/?f=_%7B238%7D%5E%7B92%7D%5Ctextrm%7BU%7D%5Crightarrow%20_%7B234%7D%5E%7B90%7D%5Ctextrm%7BRn%7D%2B_2%5E4%5Ctextrm%7BHe%7D)
F represents 234 and G represents 90.
Yes it can be.
