For the following 3 reactions identify the reactants that are Athenius bases, Bronsted-Lowry and/ lewis bases:State which type(s) of bases each reactant is, and be sure to explain your answers. a. NaOH(s) → Na+(aq) + OH-(aq)b. HF(aq ) + H2O(l) → F-(aq ) + H3O+(aq )c. H+(aq ) + NH3(aq ) → NH4+(aq )

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.

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.
