and three characteristics of nuclear reactions.
DONE

List three characteristics of chemical reactions, I have five:

occur when bonds are broken and formed

atoms remain unchanged though they may be rearranged

involve only valence electrons

reaction rate is influenced by, temp, pressure, concentration, and catalyst

Three characteristics of nuclear reactions, I have five:

occur when nuclei emit particles

atoms are often converted into atoms of another element

may involve protons, neutrons, and electrons

reaction rate is not normally affected by temp, pressure or catalyst

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

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.
