Question

Carbonated water (H2CO3) is an ingredient in soft drinks. A reaction takes place wher
carbonated water breaks down to produce water (H2O) and carbon dioxide (CO). This
occurs when a can of soft drink is opened and some of the carbon dioxide fizzes out. The above reaction is an example of :
A) combination reaction
B) double displacement reaction
C) decomposition reaction
D) displacement reaction​

Answer 1

Answer:

decomposition reaction

Explanation:

it is because H2CO3 is a weak acid and as pressure outside is lower than inside,H2CO3 breakes down to form water and carbon dioxide

H2CO3---) H2O+CO2
