Exothermic is the right answer my friend
Answer: Atoms form chemical bonds to satisfy the<u> Octet</u> rule and to become <u>stable.</u>
Explanation:
The tendency of atoms to attempt to get a noble gas configuration that is eight valence electrons is said to be octet rule. This is done to attain noble gas configuration and stability.
In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained by either by sharing of electrons or complete transfer of electrons.
For example : As we know that the sodium has one valence electron, so if giving it up then the result in the same electron configuration as the neon and chlorine has seven valence electrons, so if it takes one it will have eight and the result in the same electronic configuration as the argon which is stable.
Before you begin titration, drops of indicator are added to the Erlenmeyer flask. This happens when preparing to measure pH change.
1. The forces make the train float because the poles are the same on each side causing them to repell (north and north repell)
2. B is more stable. If you pushed A it would fall and that would cause more disturbance
It is called terminal velocity. I hope it's right though...
