Skills Lab: Combination of Matter Essential Question: When I burn something, does it get heavier or lighter? Mg + O2
TITLE: BurningMagnesium Problem: Does burning Magnesium make it heavier or lighter?
Chemical Reaction Mg + O2 +
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……..
Hypothesis: Quantitative: Mg + O2 MgO Balanced equation: 2Mg + O22MgO (Specific) Problem: How much magnesium oxide will be produced from burning ___ g of Mg?
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?
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?
X g MgO Mass of Mg 80g MgO in balanced reaction 48g Mg in balanced reaction = Predicting the mass of MgO:
