Carbon Dioxide positive test

• clear lime turns milky in the presence of carbon dioxide

• water turns milky in the presence of carbon dioxide

• none

• burning splint will make a pop in the presence of carbon dioxide

positive test for hydrogen

• burning splint will make a pop sound when in presence of hydrogen

• none

• the glowing splint will reignite in the presence of hydrogen

• burning slint will explode when in presence of hydrogen

positive test for oxygen

• none

• glowing splint will reignite when is the presence of oxygen

• glowing splint will do nothing but pop a sound when in the presence of oxygen

• lime water will change milky when in the presence of oxygen

Leibig condenser system

• ethanol has low boiling point then water, will first turn to vapor, cold water will drip it out back to ethanol

• water has low boiling point then ethanol, will first turn to vapor, cold water will drip it out back to water

• none

• the water becomes so dense that it becomes below the ethanol causing it to separate easily as the water can be scooped up and taken out of the ethanol
