What is the modern word for fixed air?
carbon dioxide. (experiment by: Jason Priestly) He put a mouse in a jar, the mouse couldn't breathe. Then he put a plant in the same jar as the mouse, and the mouse could breathe!
How an anaerobic atmosphere can be created in a jar?
To create an anaerobic atmosphere in a jar, you can displace the oxygen by adding a gas such as nitrogen or carbon dioxide. You can also use chemical agents like sodium borohydride or sodium dithionite to remove oxygen from the jar. Ensure airtight sealing to prevent any oxygen from entering the jar.
Why freshly prepared 'KOH' solution is taken in a watch-glass and kept in the bell jar during the experiment to show that carbon-dioxide is essential for photosynthesis?
The freshly prepared KOH solution is used in the experiment to absorb carbon dioxide present in the air inside the bell jar. By keeping the KOH solution in a watch-glass, any change in the color of the solution due to the absorption of carbon dioxide can be easily observed. This helps demonstrate that carbon dioxide is essential for photosynthesis by showing that the removal of carbon dioxide inhibits the process.
What is anaerobic jar in microbiology?
A catalyst in the anaerobic jar permits oxygen to combine with hydrogen that comes from a gas generator producing CO2 and H2. Sodium thioglycollate is also used in growing anaerobes and microaerophiles because it sucks up oxygen.
Would a large plant and a burning candle placed under a bell jar will the candle burn the plant because of the plant is giving off carbon dioxide?
Yes, the burning candle will use up the oxygen inside the bell jar, leading to a decrease in the oxygen levels. However, plants also require oxygen for respiration, so if the oxygen levels drop too low, both the plant and the candle may eventually be deprived of oxygen and stop burning or respiring, rather than the plant being burned by the candle.
in one of the gas jars the gas goes out immediately. name the gas in the jar?
If the gas jar is standing with its opening to the top, then the escaping gas is Hydrogen. If the gas jar is being held upside down ( opening to the bottom), then the escaping gas is carbon dioxide.
What physical property of carbon dioxide allows gas to be collected?
The physical property of carbon dioxide that allows gas to be collected is its higher density compared to air. This causes carbon dioxide to sink and accumulate in a container when released, allowing for easy collection.
What gas does a jar full of air fouled by breathing contained an excess of?
The jar would contain an excess of carbon dioxide due to exhaled breath.
What jar contained carbon dioxide?
The jar that contained carbon dioxide was typically identified during experiments involving gas collection, such as those demonstrating the respiration of yeast or the reaction of vinegar and baking soda. In these experiments, carbon dioxide is produced as a byproduct and can be captured in a jar or container. Additionally, jars used in the study of photosynthesis may show a decrease in carbon dioxide levels when plants are involved. The specific jar would depend on the context of the experiment being conducted.
What is the uses of the gas jar?
A gas jar is used in microbiology. A flame is lit in the airtight jar which starts using up the oxygen in the jar and producing carbon dioxide. This creates an environment that is lower in oxygen than the normal atmosphere and creates a perfect environment for microaerophilic microbes which need a low concentration of oxygen in order to grow. It can also make fire...
What happens when a red hot charcoal in kept in a gas jar covering it with glass lid?
when red hot charcoal is kept in glass jar then carbon reacts with oxygen present in that glass jar and forms carbon-di-oxide as major product , but a little amount of carbon monoxide is also formed .

Which gas makes burning magnesium go out immediatley?
Carbon dioxide gas can extinguish burning magnesium immediately. This is because the interaction between the magnesium and carbon dioxide produces magnesium oxide and carbon, cutting off the oxygen supply needed for the combustion reaction to continue.

Can CO be broken down chemically?
Why not, If a burning piece of Magnesium is introduced in carbon dioxide containing jar it breaks the carbon dioxide ,oxygen goes with Magnesiumas oxide and carbon is settled down.
Is air sealed in a jar a gas?
Yes it's a gas, and if it is 'air' then it's a mixture of nitrogen, oxygen, argon and tiny amounts of other gasses.
