The chemical equation for a reaction between kmno4 and hcl is shown. 2kmno4 + 16hcl → 2mncl2 + 5cl2 + 2kcl + 8h2o which of the following identifies the reactant that acts as a reducing agent in the reaction and explains the answer? kmno4, because the oxidation number of mn changes from +7 to +2. kmno4, because the oxidation number of k changes from +7 to +2. hcl, because the oxidation number of h changes from −1 to 0. hcl, because the oxidation number of cl changes from −1 to 0.

HCl, because the oxidation number of Cl changes from -1 to 0.

Explanation:

This reaction is considered as oxidation-reduction reaction that contain a reducing and oxidizing agent in the reactants.

The reducing agent is the agent that is oxidized and loss electrons and reduce the other agent.

The oxidizing agent is the agent that is reduced and gain electrons and oxidize the other agent.

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.
