Question

6. Explain why your graphs of temperature versus time exhibit an increase in temperature. Also explain why the temperature reaches a maximum and then steadily decreases. [2 points] 7. The experimental procedure states that 1.5 g of magnesium oxide are required. Will the calculated value for the enthalpy of reaction, ?H?, (Question 4) be affected if you used 1.6 g of magnesium oxide instead? Explain why or why not. [2 points] 8. Explain why the reaction is performed inside a foam cup rather than in the usual glass beaker. How would your ?T and calculated ?H? or ?H? be affected if the reaction was performed in a beaker? [2 points]
