Question

2. 21.41 What volume of hydrogen and nitrogen are required to produce 20.0 L of ammonia (all gases at STP)? 3. Acetylene (C2H2) burns in oxygen to form carbon dioxide and water. How many liters of oxygen (at STP) are needed to burn 25.0 L of acetylene at STP)? 4. Acetylene (C2H2) burns in oxygen to form carbon dioxide and water. How many liters of carbon dioxide (at STP) are formed when (25.0 L of acetylene (at STP) is burned? 5. Oxygen and hydrogen react when ignited to form water vapor. What volume of water (at STP) will be formed if 500. mL of oxygen and 500 mL of hydrogen (both at STP) are reacted? Instructors Initials Worksheet 14

Answer 1

2 So, al of niz pe 2.) Ne + 3th 2NH3 - of Nth produced from IL N₂ and 3L h. So, 20L & WH will be produced by N₂ = 20 x1 = 10L de = 20 x 3 = 30L 3.) 29th + 5O₂ - 4 CO₂ + 20 2 L Gry required 5L O₂. So, 25 L acetylene required O2 - 5x25 = 62.5 L 4.) a l of acetylene produced 4L co2 So, 25 L acetylene will produced ca x 25 - 50 L 5.) 2 + O₂ 2440 1 500 me of the require O₂ = 500- 250 ml Io present = 500 ml (or excen) so, the is limiting reagent. al of the produced al of ho so, 500 me of the will produced tho- 500 ml 500 ml produced = so, water
