Classify each of the following word equations as a synthesis, decomposition, single displacement, or double displacement reaction. Will give brainliest.

12: This is decomposition because nitrogen triiodide is breaking apart.

13: This is double displacement because the elements in the compounds are "switching".

14: This is synthesis because the water and carbon dioxide are combining.

15: This is also synthesis because the hydrogen and oxygen are combining.

16: This is single displacement because the sodium is "switching" the element it's bonding with.
