Which reaction is classified as synthesis (combination)?
A.N₂(g) + 3H₂(g) → 2NH₃(g)
B.2H₂O₂(l) → 2H₂O(l) + O₂(g)
C.Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g)
D.AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)
Explanation
Core Concept
Synthesis merges two or more simpler substances into a single compound, and here two elements unite into one product, ammonia. The many-reactants-one-product pattern is the classification cue to spot. This equation, the core of the Haber process, is the textbook example of a combination reaction.
Correct Answer
AN₂(g) + 3H₂(g) → 2NH₃(g)
