Oxidation - Reduction. Range the metals copper, lead, silver and zinc together with hydrogen to find the strongest reducing agent.
... hydrochloric acid (5.0 M), emery paper, test-tubes. Method: Burnish the three metal strips to get a shiny surface, after drop a drop of each of the metal ion solutions on the cleaned metal strips. Wash it off after a few minutes, and if there is patina present, record it. To test the reaction ...
Fire.
... heat. If the process takes place rapidly, we may see flames or an intense glow which is called fire. Chemically during combustion, two atoms of oxygen from the air combine with one atom of carbon from the fuel to form carbon dioxide. How Fires Get Extinguished? An understanding of how fires burn ...
