Stability of atoms is determined by neutron:proton ratio. This n/p ratio is 1:1 for elements below atomic number 20. Hope this helps.

Hi
The high dipole moment of water and its ease in forming hydrogen bonds make it an excellent analysis. A molecule is soluble in water if it can interact with its molecules through hydrogen bonds or ion-dipole interactions.
With anions that have oxygen they can form hydrogen bonds, since oxygen acts as their acceptor. The attraction of the anion on the water dipole must be taken into account. The same goes for Cl-F, which have solitary electron pairs and can act as hydrogen bridge acceptors. On the other hand, cations such as Na+, K+, Ca++ or Mg++ are surrounded by water molecules to which they are joined by dipole ion interactions while oxygen atoms are oriented towards the catión.

Aloha~! My name is Zalgo and I am here to help you out today. Those sort of conditions could be fore-boding/foreshadowing/warning that there will soon be a storm or that it will rain quite a lot. In the case of it being a storm, you should be a small room where there are no windows and nothing that is small that will fly towards you that could kill you.
I hope that this helps! :D

The heat capacity of calorimeter is 133.76 J/c.
What is calorimeter?
A calorimeter is a device used in calorimetry, a procedure for calculating heat capacity and trying to measure the heat of chemical reactions or even other physical changes. Among the most popular kinds are dsc calorimeters, isothermal micro calorimeters, titrimetric calorimeters, and accelerated rate calorimeters. A straightforward calorimeter is just a metal container with a thermometer suspended beyond a combustion chamber. It's one of the measurement tools used in the research of chemistry, biochemistry, and thermodynamics. The two substances A and B are separately added to a calorimeter, and the original and final temperatures are recorded, in order to determine the enthalpy change per mole of substance A in a reaction between those two substances.
We know:
mw Cw Ow = mc Cc delOc + Ccal delc
80g * 4.18/gc * (80-45)C = 80g * 4.18J/g * (45-20) + Ccal *(45-20)
= 11704J = 8360 + Ccal (25)
= 133.76 j/c
