Answer 1

Answer:

Carbon dioxide, also commonly known by its chemical formula CO2, is one of the major building blocks of life. It is usually found in its gaseous form, and is a major part of the plant and animal life cycle. CO2 is consumed by plants in photosynthesis and is produced by animals (like us!) during respiration. It is also expelled from the earth’s core during volcanic eruptions and exits a vehicle’s engine from its tailpipe when the motor is running. It’s considered a greenhouse gas, one of several compounds which contributes to global climate change. Carbon dioxide is all around us, and this simple experiment will help you see CO2 production by conducting a carbon dioxide test with two chemical reactions.

Answer 2

Answer:

Observe the colour of the gas formed in the above experiment

2. Smell the gas in the gas jar. Use separate gas jars for the octivities 3 to 7 below:

3. Remove the lid of a gas jar and put some limewater in 11. 4. Place a burning candle in a guy jar

5. Drop a small amount of a solution of some universal indicator in one gos jur filled with

CO, and shake it 6. Pour some woter in a gas jar and shake it. 7. Moisten o blue and a red litmus paper and drop them in a gas jar of CO
