In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another. For instance, chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.
Answer:
HCl is reduced and is the oxidizing agent
Explanation:
Looking at the reaction shown in the question
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
HCl is reduced to H2. The oxidation number of hydrogen decreased from +1 to zero. While magnesium was oxidized. Its oxidation number increased from zero to +2.
Hence we can rightly say that HCl was the oxidizing agent since the oxidizing agent is reduced in a reaction and the reducing agent is oxidized in a reaction.
