Capitolo 22, Problema 18
Complete the exercises below. Complete and balance the following equation: e. Na₂S (s) + HCl (aq) →
Guida verificata passo dopo passo1
Identify the reactants and products in the chemical equation. The reactants are sodium sulfide (Na₂S) and hydrochloric acid (HCl). The products will be determined by the reaction between these two compounds.
Predict the products of the reaction. Sodium sulfide (Na₂S) reacts with hydrochloric acid (HCl) to form hydrogen sulfide (H₂S) gas and sodium chloride (NaCl) in aqueous solution.
Write the unbalanced chemical equation using the predicted products: Na₂S (s) + HCl (aq) → H₂S (g) + NaCl (aq).
Balance the chemical equation by ensuring the same number of each type of atom on both sides of the equation. Start by balancing the sodium (Na) atoms, then the chlorine (Cl) atoms, and finally the hydrogen (H) and sulfur (S) atoms.
Verify that the equation is balanced by counting the atoms of each element on both sides of the equation. Adjust coefficients as necessary to achieve balance.
Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Balancing Chemical Equations
Balancing chemical equations is essential to ensure that the law of conservation of mass is upheld, meaning the number of atoms of each element must be the same on both sides of the equation. This involves adjusting coefficients in front of the chemical formulas to achieve balance without changing the actual compounds involved.

Balancing Chemical Equations
Types of Chemical Reactions
Understanding the types of chemical reactions, such as acid-base reactions, is crucial for predicting the products of a reaction. In this case, sodium sulfide (Na₂S) reacts with hydrochloric acid (HCl), which typically results in the formation of a salt and hydrogen sulfide gas (H₂S), illustrating an acid-base neutralization.

States of Matter in Reactions
Recognizing the states of matter (solid, liquid, gas, aqueous) is important for interpreting chemical equations. In the given reaction, Na₂S is a solid (s) and HCl is an aqueous solution (aq), which influences the reaction dynamics and the physical state of the products formed, such as whether a gas is released or a precipitate forms.
