Halogen are the most reactive due to their electronic configuration
You multiply the number of atoms by 12 to get how many electrons (since each atom has 12 electrons in it)
you multiply the number of atoms by 13 to get how many neutrons
(since each atom of this isotope has 13 neutrons in it)

Answer:
FIREWORKS : WHEN FIREWORKS EXPLODE THEY EXPEL SMOKE WHICH IS A FORM OF GAS AND THEY LIGHT UP WHICH IS ANOTHER CHEMICAL REACTION AND OF COURSE THE WHOLE FIREWORK GETS HOT ( Temperature rises )
Explanation:
you could see your reaction happens when original substance changes in color temperature formation produces light or gas in many other things
( besides it's original form! )
answer what changed from it's original form!
ex: baking a cake:
the cake change form ( rising ) due to heat ( rising temperature )
REACTION WAS:
- formation of precipitate ( solid to settle out of a solution )
- change I'm temperature to bake the cake
Extra:
you got this!
I hope I helped even just a little!
