1. Germanium (Ge) has a diamond lattice with an atomic density of 4.42x1022 atoms/cm3 , while aluminum (Al) is a face-centered cubic with atomic density of 6.02x1022atoms/cm3 . a) Calculate the lattice parameter a for Ge and Al. b) Determine the number of atoms/cm2 on the (100), (110), and (111) surfaces for Ge and Al

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.
