Balance the following equations and indicate whether they are combination, decomposition, or combustion reactions: (b) NH₄NO₃(s) → N₂O(g) + H₂O(g)

Key Concepts

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 based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing is crucial for accurately representing the reaction and predicting the amounts of reactants and products.

Types of Chemical Reactions

Chemical reactions can be classified into several types, including combination, decomposition, and combustion reactions. A combination reaction involves two or more substances combining to form a single product, while a decomposition reaction involves a single compound breaking down into two or more products. Combustion reactions typically involve a substance reacting with oxygen, producing heat and light.

Decomposition Reactions

Decomposition reactions occur when a single compound breaks down into two or more simpler substances, often due to heat, light, or electricity. In the given equation, ammonium nitrate (NH4NO3) decomposes into nitrous oxide (N2O) and water (H2O). Recognizing this type of reaction is essential for classifying the reaction correctly and understanding the underlying chemical processes.
