Metal Oxides Flashcards
How did the understanding of chemical changes begin?
It began when people experimented with chemical reactions systematically and organized their results logically.
What did knowing about different chemical changes allow scientists to do?
It allowed them to predict exactly what new substances would be formed and use this knowledge to develop a wide range of materials and processes.
How has this understanding benefited biochemists?
It has helped biochemists understand the complex reactions that take place in living organisms.
How is the extraction of important resources from the earth related to chemical reactions?
It makes use of how some elements and compounds react with each other and how easily they can be ‘pulled apart.
What happens when metals react with oxygen?
They produce metal oxides, and these reactions are oxidation reactions because metals gain oxygen.
What skill should students develop regarding reduction and oxidation?
They should be able to explain reduction and oxidation in terms of the loss or gain of oxygen.
