Reaction of non-metals with oxygen

The video tutorial demonstrates an experiment where coal is burned in an oxygen jar, producing carbon dioxide. This gas is then dissolved in water to form carbonic acid, which turns violet litmus solution red. The experiment illustrates how non-metals react with oxygen to form non-metal oxides, using carbon as an example.

What is the first step in the experiment involving the oxygen jar?

• Adding water to the jar

• Lighting the burner

• Placing the jar on the table

• Adding litmus solution

What gas is produced when coal is burned in the oxygen jar?

• Hydrogen

• Carbon dioxide

• Nitrogen

• Oxygen

What happens when water is added to the carbon dioxide gas in the jar?

• It forms hydrochloric acid

• It forms nitric acid

• It forms sulfuric acid

• It forms carbonic acid

What color does the litmus solution turn when carbonic acid is formed?

• Red

• Green

• Yellow

• Blue

What conclusion can be drawn about non-metals reacting with oxygen?

• They form basic solutions

• They do not react

• They form non-metal oxides

• They form metal oxides
