Among ¹⁴⁰₅₅Cs and ¹³³₅₅Cs, <u>¹³³₅₅Cs</u> is more stable.
<h3>Briefly explained</h3>
Let's review the criteria that are used to determine a stable isotope. A stable isotope will have more neutrons than protons with a neutron to proton ratio somewhere between one and 1.52 On the high atomic number, we're up to 152 at low atomic numbers were closer to one. More stable isotopes have an even number of protons. And neutrons.
And stable isotopes have their proton or neutron number equal to one of these magic numbers. So if we have season one, It has 85 Protons are start 85 neutrons And 55 protons. So we have a neutron to proton ratio of 155 for CCM 1 33. We have 78 neutrons and 55 protons for a neutron to proton ratio of 1.42. 155 is a little high for z equal to 55.
Both of these are also odd. So ¹⁴⁰₅₅Cs is the least stable. ¹³³₅₅Cs is the most stable.

Tendons<span> may also attach muscles to structures such as the eyeball. A </span>tendon<span> serves to move the bone or structure. A </span>ligament<span> is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.</span>
Answer:
The compound which will precipitate first will be AgI with 
Explanation:
In order to precipitate a salt solution the ionic product of salt must exceed the solubility product.
Given:
Ksp of AgI = 
Ksp of PbI2= 
As Ksp of AgI is very low it will precipitate faster than lead iodide.
Now, higher the concentration of AgI solution taken faster its precipitation.
In the given choice the highest concentration solution of AgI is
Answer: (D) it is not spontaneous.
We use a process called electrolysis to break apart water molecules into hydrogen and oxygen. Meaning electrolysis use an electrical current to split the molecule apart
