Balance the following equations. (c) NH₄ClO₄ + Al → Al₂O₃ + N₂ + Cl₂ + H₂O

Guida verificata passo dopo passo

Write down the unbalanced chemical equation: NH_4ClO_4 + Al → Al_2O_3 + N_2 + Cl_2 + H_2O.

List the number of each type of atom on both sides of the equation to identify which elements are unbalanced.

Start by balancing the metals: Balance the aluminum (Al) atoms by ensuring the number of Al atoms on the reactant side equals the number on the product side.

Balance the non-metals: Balance the nitrogen (N), chlorine (Cl), and oxygen (O) atoms by adjusting coefficients as needed.

Finally, balance the hydrogen (H) atoms by adjusting the coefficient of H_2O, and check that all elements are balanced.

Concetti chiave

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 of each element is the same on both sides of the equation. This is achieved by adjusting the coefficients in front of the chemical formulas. The law of conservation of mass dictates that matter cannot be created or destroyed in a chemical reaction, thus requiring balanced equations.

Stoichiometry

Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. It allows chemists to calculate the amounts of substances consumed and produced in a reaction based on balanced equations. Understanding stoichiometry is essential for predicting yields and determining the proportions of reactants needed.
