Question

What happens to the atoms that make up ethanol as it burns?

Answer 1

Answer:

Ethanol is a chemical compound made up of carbon, hydrogen and oxygen atoms. The chemical formula of ethanol is . When ethanol is burnt, it reacts with oxygen and produces water and carbon dioxide. ... In summary, when ethanol burns, it reacts with oxygen to produce carbon dioxide, water and heat.

Inside the flame the ethanol and oxygen molecules come together and go through a chemical

change. Let’s think about matter—the atoms. The atoms in both the ethanol (C2H5OH) and the

oxygen (O2) molecules rearrange into carbon dioxide (CO2) and water (H2O). The number of atoms

does not change. We can use a chemical equation to show how the atoms are rearranged:

C2H5OH + 3 O2 à 2 CO2 + 3 H2O

Explanation:

Answer 2

Answer:

When ethanol is burnt, it reacts with oxygen and produces water and carbon dioxide. The chemical equation of the combustion of ethanol i

When ethanol is burnt, it reacts with oxygen and produces water and carbon dioxide. The chemical equation of the combustion of ethanol iThe combustion of ethanol is an exothermic reaction. In addition to the formation of new compounds, the chemical reaction that takes place when ethanol is burnt also releases a lot of heat, 277.7 kJ per mole of ethanol.

when ethanol burns, it reacts with oxygen to produce carbon dioxide, water and heat.
