a horde of zombies is heading south at 67.8 km/hour. Your school is 55,241 meters South of the horde. How many minutes warning do you have?

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

the dissolution of polymer can be thermodynamically described in 2 steps.

you need to have a picture of the atom that way we can answer it
