Capitolo 3, Problema 107c
Write the balanced chemical equation for each reaction. c. Aqueous hydrochloric acid reacts with solid manganese(IV) oxide to form aqueous manganese(II) chloride, liquid water, and chlorine gas.
Guida verificata passo dopo passo1
Identify the reactants and products in the chemical reaction: Reactants are hydrochloric acid (HCl) and manganese(IV) oxide (MnO2). Products are manganese(II) chloride (MnCl2), water (H2O), and chlorine gas (Cl2).
Write the unbalanced chemical equation using the chemical formulas: HCl(aq) + MnO2(s) -> MnCl2(aq) + H2O(l) + Cl2(g).
Balance the equation by adjusting coefficients to ensure the same number of each type of atom on both sides of the equation. Start by balancing the manganese (Mn) atoms.
Next, balance the chlorine (Cl) atoms. Since Cl appears in both HCl and Cl2, adjust the coefficients accordingly.
Finally, balance the hydrogen (H) and oxygen (O) atoms by adjusting the coefficients of HCl and H2O.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Balancing Chemical Equations
Balancing chemical equations involves ensuring that the number of atoms for each element is the same on both the reactant and product sides. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Each side of the equation must have equal numbers of each type of atom, which often requires adjusting coefficients in front of the chemical formulas.
