Element Mixture Or Compound

The video tutorial explains the differences between mixtures and compounds using iron and sulfur as examples. It demonstrates four tests on iron and sulfur elements, a mixture of the two, and the compound iron sulfide. The tests include appearance, action of water, reaction with hydrochloric acid, and magnetic properties. The results show that mixtures retain the properties of their components, while compounds exhibit new properties due to chemical bonding.
