Four flasks each contain 100 milliliters of aqueous solutions of equal concentrations at 25°C and 1 atm. KCI
CH3OH
Ba(OH)2
CH3COOH

Which solutions contain electrolytes?

KCl and Ba(OH)₂.

Explanation:

Hello there!

In this case, since electrolytes are substances characterized by presence of covalent bonds between the atoms forming the compound, it is possible to realize that just KCl and Ba(OH)₂ as they are species composed by cations (K and Ba) and anions (OH and Cl); therefore, they have the capacity to get ionized in aqueous solution and thus transfer electricity when present.

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.
