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
