Question 1
A particular coal sample contains 2.32% S. When the coal is burned, the sulfur is converted to sulfur dioxide gas. What volume (L) of SO
2(g), measured at 25°C and 749 mmHg, is produced by burning 2.0 × 10
6 lb of this coal? (1 lb = 454 g)
Question 2
In an effort to address concerns about global warming, a power plant in Portland,Oregon is designed to take all of its exhaust gases from its boilers and recycle the CO
2 using the Solvay process to make sodium hydrogen carbonate. The reaction is shown below.
NH
3(g) + H
2O(l) + CO
2(g) + NaCl(aq) → NaHCO
3(aq) + NH
4Cl(aq)
How many liters each of NH
3 and CO
2 (both at STP) would be consumed to produce 3.00 kg of sodium bicarbonate?
