Question

Identify the following chemical reactions as Synthesis or Decomposition reactions

1: NaCIO3 --> NaCI +O2

2: P4+CI2 --> PCI3

3: BaO+SO3 --> BaSO4

Answer 1

NaCIO3 --> NaCI +O2

This is decomposition reaction in this one compound decomposes or break down to two other compounds

2: P4+CI2 --> PCI3

3: BaO+SO3 --> BaSO4

Thes are synthesis reaction in which one compound is synthesized from two compounds.
