Identify the following chemical reactions as Synthesis or Decomposition reactions 1: NaCIO3 --> NaCI +O2

2: P4+CI2 --> PCI3

3: BaO+SO3 --> BaSO4

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.

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
