1. Write the balanced chemical equations for the following reactions and identify the type of reaction.Ethene is burnt in the presence of oxygen to form carbon dioxide, water and releases heat and light.
  
When ethene is burned in the presence of oxygen, it produces carbon dioxide, water, heat and light.
The following reaction occurs:
 
+ heat + light
 
The reaction described above is reaction.
A combustion reaction is a reaction that takes place in the presence of oxygen to form carbon dioxide.
  
2. Write the balanced chemical equations for the following reactions and identify the type of reaction.
Ethanol is burnt in air to form carbon dioxide, water and releases heat.
  
+ \(3H_2O\)​(aq) + Heat

This is an example of reaction.
 
When ethanol (\(C_2H_5OH\)) burns in the presence of oxygen (\(O_2\)), it produces carbon dioxide (\(CO_2\)) and water (\(H_2O\)) as well as heat.
