5. (4.2) One way of obtaining pure sodium carbonate is through the decomposition of the mineral
trona, which has the formula Nas(CO3)2(HCO3)-2H2O. Sodium carbonate is isolated from the
reaction below.
Nas(CO3)2(HCO3)-2H2O(s) →Na2CO3(s) + CO2(g) +3H₂O(g) (unbalanced)
When 1.00 kg of trona was decomposed, 0.47 kg of Na2CO3 was recovered. What was the percent
yield of this reaction?
