Which of these chemical equations is correctly balanced?
2 answers:
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. Total mass on the reactant side will always be equal to the total mass on the product side.
Every balanced chemical reaction follows law of conservation of mass.
From the given options, only option is balanced, which is Equation C.
Equation C:
<u>On reactant side:</u>
The number of Manganese atoms are 1, number of oxygen atoms are 20, number of carbon atoms are 8 and number of hydrogen atoms are 8.
<u>On product side:</u>
The number of Manganese atoms are 1, number of oxygen atoms are 20, number of carbon atoms are 8 and number of hydrogen atoms are 8.
Thus, the above equation is balanced chemical equation and the correct answer is option C.

Answer : The most likely happens during this reaction is, Oxidation-reduction
Explanation :
The balanced reaction will be,
In this reaction, neutral iron loses 3 electrons and oxidizes in (+3) state, and neutral oxygen gains 2 electrons and reduces in (-2) state,
When iron react with oxygen gas to give iron oxide. This process is known as iron rusting. During the reaction, oxidation-reduction process occurs.
Oxidation : It is a type of chemical reaction in which a substance loses its electrons. Or we can say that in oxidation, the oxidation number increases.
Reduction : It is a type of chemical reaction in which a substance gains its electrons. Or we can say that in reduction, the oxidation number decreases.
