Question

1. what type of reaction is represented by the equation 2na + cl₂ → 2nacl?

a. decomposition reaction
b. combustion reaction
c. displacement reaction
d. synthesis reaction

Explanation:

• Decomposition Reaction: A single compound breaks down into two or more simpler substances. Here, we have two reactants combining, not a single compound decomposing.
• Combustion Reaction: Usually involves a substance reacting with oxygen (e.g., \(C + O_2

ightarrow CO_2\)). There is no oxygen - related reaction in \(2Na+Cl_2
ightarrow 2NaCl\).

• Displacement Reaction: One element displaces another in a compound (e.g., \(Zn + CuSO_4

ightarrow ZnSO_4+Cu\)). In our equation, we are combining two elements (\(Na\) and \(Cl_2\)) to form a compound, not displacing.

• Synthesis Reaction: Two or more reactants combine to form a single product. In \(2Na + Cl_2

ightarrow 2NaCl\), sodium (\(Na\)) and chlorine (\(Cl_2\)) combine to form sodium chloride (\(NaCl\)).

Answer:

d. Synthesis Reaction
