You have 100 mL of 0.250M KMnO4. If you transfer 12.9mL of this solution to an Erlenmeyer flask and add 75.0mL of water, what is the concentration of the solution in
the Erlenmeyer flask? What is the concentration of the solution in the original bottle?

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

it's all four options.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
