In an investigation, a dripless wax candle is massed and then lighted. As the candle burns, a small amount of liquid wax forms near the flame. After 10 minutes, the candle’s flame is extinguished and the candle is allowed to cool. The cooled candle is massed. a. Identify one physical change that takes place in this investigation. __________________________________________________________________________________________ __________________________________________________________________________________________ b. Draw a particle diagram showing the change from solid wax to liquid wax. Use BEFORE for particles of wax. AFTER 2. When solid magnesium, Mg combines with oxygen gas, O2, to form solid magnesium oxide, MgO, an intense bright white flash is produced which can result in temporary blindness if looked at directly. ATOM KEY: Physical or Chemical Change? _____________________________ = Mg =O 3. Steam (gaseous water) from a turbine in order to produce electricity. As the gaseous water exits the it condenses into the liquid form. Physical or Chemical Change? _____________________________ ATOM KEY: BEFORE =O AFTER =H turbine
