Chemical change forms a new substance from another substance.
An organic compound "X" on heating with H2SO4 forms a compound "Y" which on addition of one molecule of hydrogen in the presence of nickle forms a compound "Z". One molecule of compound "Z" on combustion forms two molecules of co2 and three molecules of H2O. identify giving reasons the compounds, "X", "Y", and "Z", write the chemical equations for call the chemical reactions involved
Chemical change or chemical reaction describes how a substance can form a new substance.
when a substance undergoes a chemical change the original form cannot be recognized and it could get total new properties.
Oxidation
Chemical change forms a new substance from another substance.
The change were new material is produce is called chemical change.
