Assume the diameter of a neutral helium atom is 1.40 × 102 pm. suppose that we could line up helium atoms side by side in contact with one another. how many atoms would it take to make the distance 6.20 cm from end to end?

many atoms would it take to make the distance 6.20 cm from end to end.

Explanation:

Diameter of the helium atom =  

Let the number of atoms required to make the distance 6.20 cm be n.

many atoms would it take to make the distance 6.20 cm from end to end.

what are the two models

explanation:

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.
