1.The limewater is used to test for the presence of carbon dioxide when a living thing respires.
2. The limewater turns chalky.
3. The limewater remains clear.
4. Jar A: The mouse in Jar A respires and gives off carbon dioxide. The carbon dioxide interacted with the limewater and caused it to turn chalky.
Jar B As the toy mouse is a non-living thing, it does not respire. No carbon dioxide is given off and the limewater remains clear.
5. When Latiff blew into the limewater, the carbon dioxide given out interacts with the limewater and caused it to turn chalky.
