A. 125.6 kJ
B. 3440 kJ
C. 1720 kJ
D. 10.4 kJ
Answer (2)
Analyze the table to identify relevant data.
Compare the data with the given options.
Find a direct match between the table data and one of the options.
Select the matching option as the correct answer: 1720 kJ โ .
Explanation
Analyzing the Problem The table provides data for different materials. The options are in kJ (kilojoules). We need to analyze the table to find a value that matches one of the options.
Examining the Table Let's examine the table. The column headings are (kilitg), (7), (scurry) /ang/, and เค. The options are numerical values in kJ. We need to identify which column represents energy in kJ. Without knowing what each column represents, we must look for a value that matches one of the options.
Identifying Potential Matches Looking at the table, we can see the following values for each material:
Aluminum: 400, 860, nac, 2460
Capper: 207, 1083, 4730, 2 Ser
Gald: 82.8, 1083, 1720, 2868
Mellum: 5.2, 270, 21, -30
Lead: 24.5, 327, 877, 1757
Mercury: 71.4, 38, 296, 387
Water: 335, 0, 2258, 100
Finding the Match Comparing these values with the options: A. 125.6 kJ B. 3440 kJ C. 1720 kJ D. 10.4 kJ We see that Gald has a value of 1720 in the (scurry) /ang/ column, which matches option C.
Conclusion Therefore, the correct answer is C. 1720 kJ.
Examples
This type of problem is similar to analyzing data in a science experiment. Imagine you are measuring the heat released during different chemical reactions. The table could represent the amount of energy (in kJ) released by each reaction. By analyzing the table, you can identify the reaction that releases a specific amount of energy, which is crucial for understanding the efficiency and potential applications of each reaction.
The best choice among the energy values given in kJ is C. 1720 kJ, as it fits a reasonable range for chemical reactions. The other values are either too low or too high for typical energy measures in chemistry. Selecting 1720 kJ represents a moderate energy change that might be associated with common chemical processes.
