What gas is collected when a uninflated balloon is placed round a test tube of yeast?
Carbon dioxide gas is collected when a uninflated balloon is placed around a test tube of yeast. This is because the yeast produces carbon dioxide gas as a byproduct of the fermentation process.
How could a burning splint be used to tell if gas were oxygen or carbon dioxide?
A burning splint can be used to test for oxygen or carbon dioxide by observing the splint's reaction. If the splint is placed in a container with oxygen, it will reignite or burn more vigorously due to the increased availability of oxygen for combustion. In contrast, if the splint is placed in carbon dioxide, it will extinguish, as carbon dioxide does not support combustion. This simple test helps differentiate between the two gases based on their effects on a flame.
When Acid is placed into limestone and produces carbon dioxide gas is this a physical or a chemical change?
This is a chemical change.
What happens to an egg when placed into sparkling water?
When an egg is placed into sparkling water, the carbon dioxide bubbles in the water adhere to the surface of the egg, creating a fizzy layer around it. This can create a fizzy appearance as the bubbles cling to the eggshell. However, it does not have any significant impact on the egg itself.
What will happen to a tied balloon that has dry ice inside it when it is placed in room temperature water?
The balloon should expand because the frozen carbon dioxide (dry ice) will sublime into carbon dioxide gas when placed into the room temperature water. The gas will expand, causing the balloon to expand.
Would a glowing splint placed into carbon dioxide gas glow more brightly or reignite?
Neither, because it dies out. See the answer to the question "what happens to a glowing splint....."
When dry ice placed in water we see bubbles rise these bubbles are made of carbon dioxide in what state?
The bubbles consist of carbon dioxide gas in the gaseous state.

Where is a carbon dioxide monitor to be mounted top of wall or next to floor?
Carbon Dioxide is heavier than air so the monitor will work best near the floor. However is your monitor for Carbon Dioxide or Carbon Monoxide. If the latter, CO detectors can be placed near the ceiling or near the floor because CO is very close to the same density as air.
Some salt and acid was placed in a test tube. The lime water turned milky.What is the name of this gas?
carbon dioxide
What is made of frozen carbon dioxide?
'Card ice' -which is used in theatres to mimic mist or smoke when placed in warm water.
Why does a candle go out when dry ice is placed near it?
Gaseous carbon dioxide is released and this gas doesn't support burning.
Where can you find a cell that gives off oxygen and carbon dioxide?
well plant cells produce oxygen naturally and when placed in an environment without light they will also breath and produce carbon dioxide so in a way they will produce both

What would you observe on adding dilute hydrochloric acid to sodium bicarbonate placed in a test tube?
You would observe effervescence (bubbling) due to the release of carbon dioxide gas. The reaction produces sodium chloride, water, and carbon dioxide.
