Determine the type of reaction: h2o + c16h17nao14 = co2 + h20 + c2h3nao3?
a.) single replacement
b.) synthesis
c.) decomposition
d.) double replacement

It is the type of Decomposition reaction.

Explanation:

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds.

In this reaction , C16H17NaO14 decomposes to give carbon dioxide and C2H3NaO3.

That's why , this reaction is a decomosition reaction.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
