A 5.00 gram sample of a dry mixture of potassium hydroxide, potassium carbonate, and potassium chloride is reacted with 0.100 liter of 2.00 molar HCl solution. Molecular Structure and Bonding : You can find

Urea (H₂NCONH₂) is produced commercially from the reaction of ammonia and carbon dioxide: 2NH₃(g) + CO₂(g) → H₂NCONH₂(s) + H₂O(g). Ammonia gas at 223°C and 90 atm flows into a reactor at a rate of 500 L/min. Carbon dioxide at 223°C and 45 atm flows into the reactor at a rate of 600 L/min. What mass of urea is produced per minute by this reaction assuming a 74% yield?

0.200 minus 0.0200 minus 0.130 equals 0.050 mol cap H cap C l cap K cap O cap H Since the ratio is 1:1:

$$ \textMoles O = \frac0.211\text g16.0\text g/mol = 0.0132\text mol $$

(a) A 249 milliliter sample of dry CO₂ gas, measured at 22°C and 740 torr, is obtained from this reaction. What is the percentage of potassium carbonate in the mixture?
