Question

Part II : Volume - Volume 1. Carbon monoxide burns in oxygen to form carbon dioxide. What volume of oxygen at 25°C and 760. mm Hg is required to react with 15.0 L of carbon monoxide (at STP)? 2. What volume of hydrogen and nitrogen are required to produce 20.0 L of ammonia (all gases at STP)? 3. Acetylene ( CH) 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 bumed? 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
