Questions asked by users might not always be phrased in the clearest way.
Here are some common types of chemical reactions:
Combination Reaction: Two or more reactants combine to form a single product.
Example: 2H₂ + O₂ → 2H₂O
Decomposition Reaction: A single reactant breaks down into two or more products.
Example: 2H₂O₂ → 2H₂O + O₂
Single Displacement Reaction: One element replaces another in a compound.
Example: Zn + CuSO₄ → ZnSO₄ + Cu
Double Displacement Reaction: Two reactants exchange ions to form two new compounds.
Example: AgNO₃ + NaCl → AgCl + NaNO₃
Combustion Reaction: A substance reacts rapidly with oxygen, releasing heat and light.
Example: CH₄ + 2O₂ → CO₂ + 2H₂O
Acid-Base Reaction: An acid reacts with a base to form salt and water.
Example: HCl + NaOH → NaCl + H₂O
