Question

give 10 examples of photolytic decomposition. ​

Answer 1

Answer:

Carbonic acid (H2CO3) is an ingredient in soft drinks. A decomposition reaction takes place when carbonic acid breaks down to produce water (H2O) and carbon dioxide (CO2). This occurs when you open a can of soft drink and some of the carbon dioxide fizzes out. The equation for this reaction is:

H2CO3 → H2O + CO2

Another decomposition reaction occurs when water (H2O) breaks down to produce hydrogen (H2) and oxygen (O2) gases (see Figure below). This happens when an electric current passes through the water, as illustrated below. The equation for this reaction is:

2 H2O → 2 H2 + O2
