One Way of Obtaining Pure Sodium Carbonate Is Through the Decomposition

question 68

Multiple Choice

One way of obtaining pure sodium carbonate is through the decomposition of the mineral trona, Na₃(CO₃) (HCO₃) ·2H₂O. 2Na₃(CO₃) (HCO₃) ·2H₂O(s) → 3Na₂CO₃(s) + CO₂(g) + 5H₂O(g)
When 1.00 metric ton (1.00 × 10³ kg) of trona is decomposed, 0.650 metric ton of Na₂CO₃ is recovered. What is the percent yield of this reaction?

• A) 92.4%
• B) 72.1%
• C) 65.0%
• D) 48.1%
• E) 35.0%
