  1. Skills Lab: Combination of Matter Essential Question: When I burn something, does it get heavier or lighter? Mg + O2

  2. TITLE: BurningMagnesium Problem: Does burning Magnesium make it heavier or lighter?

  3. Chemical Reaction Mg + O2 +

  4. Aim:Does burning Magnesium make it heavier or lighter? What type of chemical reaction is involved? Hypothesis: A statement that predicts what will happen. Use the structure: ‘If…then…because…’ Qualitative hypothesis: If Magnesium is ignited/burned, then…… because……..

  5. Hypothesis: Quantitative: Mg + O2 MgO Balanced equation: 2Mg + O22MgO Problem: How much magnesium oxide will be produced from burning ___ g of Mg?

  6. How much magnesium oxide will be produced from burning 0.24g of Mg? Mass of Magnesium: 0.24 g Mass of container: _____ Mass (initial) of Magnesium and container: _____ Mass (final) of Magnesium and container: _____ Predicted Mass of MgO: _______ Final Mass of MgO: _______ heavier or lighter than Mg?

  7. AIM: Does burning Magnesium make it heavier or lighter? How do you burn? Partial or complete? Burning of Magnesium Mass of Magnesium Mass of Mg (initial mass) Mass of Mg and container Complete burning To prevent errors

  8. Set-up and procedure: • What materials are you going to use? Draw your set-up. • How would you design your test? Write a step by step procedure. Do not look at burning Mg directly. It may cause damage to your eye?

  9. Hypothesis: Quantitative: Mg + O2 MgO Balanced equation: 2Mg + O22MgO Atomic Mass: 24 16 40 (2 x 24) (2 x 16) (2 x 40) 48 32 80 How much magnesium oxide will be produced from burning 0.24g of Mg?

  10. X g MgO Mass of Mg 80g MgO in balanced reaction 48g Mg in balanced reaction = Predicting the mass of MgO:
