what is the balanced equation when copper metal is placed in a solution when platnium ii chloride is placed. what is the equation

Explanation:

In this case, we can start with the formula of Platinum (II) Chloride. The cation is the atom at the left of the name (in this case ) and the anion is the atom at the right of the name (in this case ). With this in mind, the formula would be .

Now, if we used metallic copper we have to put in the reaction only the copper atom symbol . So, we have as reagents:

The question now is: What would be the products? To answer this, we have to remember "single displacement reactions". With a general reaction:

With this in mind, the reaction would be:

I hope it helps!

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
