Complete and balance each equation. If no reaction occurs, write 'NO REACTION.' a. LiI(aq) + BaS(aq)

Guida verificata passo dopo passo
1
Identify the reactants: LiI(aq) and BaS(aq).
Determine the possible products by exchanging the ions: Li+ with S2- and Ba2+ with I-.
Write the potential products: Li2S and BaI2.
Check the solubility of the products: Li2S is soluble, BaI2 is soluble.
Since both products are soluble, no precipitate forms, so the reaction is 'NO REACTION.'

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Double Displacement Reaction

A double displacement reaction, also known as a metathesis reaction, occurs when the anions and cations of two different compounds exchange places to form two new compounds. This type of reaction typically takes place in aqueous solutions and can result in the formation of a precipitate, gas, or a weak electrolyte.

Solubility Rules

Solubility rules are guidelines that help predict whether a compound will dissolve in water. For example, most alkali metal salts and ammonium salts are soluble, while many sulfides and carbonates are not. Understanding these rules is crucial for determining if a reaction will occur and if any products will precipitate out of solution.

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the number of atoms for each element is the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Properly balancing equations is essential for accurately representing the stoichiometry of the reaction.
