3. PROPERTIES From this following description, determine all the properties of hydrogen that fit each of the following classifications: ExtensiveIntensive ChemicalPhysical

4. PROPERTIES A sample of hydrogen has a volume of 1.2 liters. The sample is a colorless, odorless gas. When a sample is added to a sample of oxygen and a spark is struck, an explosion occurs and (if the container doesn’t break) water can be found as a product of the explosion.

5. CHEMICAL or PHYSICAL CHANGES? Making an iron bar into a magnet Burning a sample of carbon Ice cubes “shrink” over time in the freezer Steel forms red rust when exposed to air Sugar dissolves in water

6. CHEMICAL or PHYSICAL CHANGES? Heating a sample of ice until it melts Grape juice ferments into wine Tearing a sheet of paper into tiny pieces Fusion of hydrogen to helium in the sun
