Relative atomic mass (Ar): Mg = 24 Relative formula mass (Mr): MgO = 40 [2 marks] Percentage mass of magnesium = % Question 1 continues on the next page4 *04* IB/M/Jun21/8464/C/1F Do not write outside the box 10 Magnesium carbonate decomposes to produce magnesium oxide and carbon dioxide. The word equation for the reaction is: magnesium carbonate → magnesium oxide + carbon dioxide Four students heated 2.00 g of magnesium carbonate for 10 minutes. Table 1 shows the results. Table 1 Mass of carbon dioxide produced in g Student 1 Student 2 Student 3 Student 4 Mean 0.97 0.91 0.50 0.95 X 0 1 . 6 What is the most likely reason for Student 3’s anomalous result? [1 mark] Tick () one box. The student heated more than 2.00 g of magnesium carbonate. The student heated the magnesium carbonate for less than 10 minutes. The student used a higher temperature. 0 1 . 7 Calculate value X in Table 1. Do not use the anomalous result. Give your answer to 2 significant figures.
