Question

Use Dalton’s atomic theory to explain what is happening to the carbon atoms when a diamond is burned and to oxygen and hydrogen atoms when water is electrolyzed.

Answer 1

Answer:

Diamond is burnt

Diamond (Carbon)+ Oxygen → CO2

Water electrolysed

2H2O → 2H2 + O2

Explanation:

Dalton atomic theory states that in a chemical reaction, the atoms of the elements join together or combine in simple whole number ratios

Hence when, at very high temperatures, diamond which consists of carbon is burnt we have

Diamond (Carbon)+ Oxygen → CO2

Also when water is electrolysed it decomposes as follows

2H2O → 2H2 + O2
