In the following redox reaction, the reducing agent is MnO2 (option D). Details about reducing agent can be found below.
<h3>What is a reducing agent?</h3>
A reducing agent in a redox reaction is any substance that reduces, or donates electrons to another, hence, it becomes oxidized.
According to this question, a redox reaction is given as follows: MnO2(s) + 4H+(aq) + 2Cl–(aq) = Mn2+(aq) + 2H2O(l) + Cl2(g)
As shown in the equation, MnO2 is oxidized into Mn2+, therefore, it is the reducing agent.

Answer:
Adiabatic. This is a process where no heat is being added or removed from the system. Or can be simply stated as: no heat transfer (or heat flow) happening in a system.
Explanation:
Answer:
Positive; negative
Explanation:
When electrons are lost, a positive ion is formed. A positive ion is called a cation.
When electrons are gained, a negative ion is formed. A negative ion is called an anion.
Answer:
Scandium is the most reactive
