Explanation:
First of all , there were a total charge of +13e (6 protons from carbon and 7 protons from nitrogen), that meant there requires to be a total charge of +13e after the collision occurred. Listed is 16 protons (+16e), 3 antiprotons (-3e), 8 positrons (+8e) and 16 neutral particles (0e), so the total charge listed is +21e, meaning an excess of +8e, meaning you need 8 electrons (-8e) to balance out the charge.
Now, i might be wrong but, you have to make a hypotosis of possible theories as to what the truck is doing. Then observe what changes were made after the salt was added then the question should be why was the salt added and how it changed the area. I hope this helps!
