When an effective catalyst is added to the reactant mixture, the reaction rate increases. sketch energy profiles both uncatalyzed and catalyzed reactions (e. g. use solid and dash lines). label reactants, products, transition states. the change of enthalpy, and activation energies of both reactions on the diagranm (8 pts.) a one-step exothermic chemical reaction a + b ? c +d occurs very slowly being uncatalyzed. reaction progress

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.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
