Identify the reduced substance, the oxidized substance, the reducing agent, and the oxidizing agent in the reaction of zinc with copper ions. Zn(s)+Cu2+(aq)⟶Zn2+(aq)+Cu(s) Which substance in the reaction gets reduced?

Zinc is the oxidized substance and therefore the reducing agent.

Copper is the reduced substance and therefore the oxidizing agent.

Explanation:

Hello.

In this case, since the following chemical reaction is a redox one because the oxidation states of the species there are changed, the first step is to assign the oxidation states for all the species there as shown below:

Since metallic zinc a copper are pure elements so they are not oxidized. Now, since zinc increases its oxidation state from 0 to +2, we infer zinc is the oxidized substance and therefore the reducing agent. Moreover, since copper decreases its oxidation state from +2 to 0, we infer copper is the reduced substance and therefore the oxidizing agent.

Constitutional Monarch had its origins when King John was compelled to sign the Magna Carta that protected the barons from abusive of power from the king.  Later during the rise of Parliament, they presented the Bill of Rights that laid down a list of rights of individuals that further limited the power of the nobility.  When the English Civil War ended, the monarchy was restored but so as not to anger parliament, constitutional monarchy was establish that gave more power to the parliament than the king.
