What gas is collected when a uninflated balloon is placed round a test tube of yeast?
CO2.
How do you test for carbon dioxide with a splint?
collect gas from reaction with a test tube, then light spint and insert into the gas filled tube. if splint is extinguished immediately, then its CO2. but limewater test is more reliable
Which gas is used for the preparation of Soda water?
Carbon dioxide or CO2.
What happens to a gas produced in a reaction?
it depends on what is reacting most commonly it is H2 gas or O2 gas or CO2 gas
How could you find out if a colorless gas is CO2 or hydrogen?
One way to identify the gas is to pass it through lime water (calcium hydroxide solution). If the gas turns the lime water milky white, it indicates the presence of carbon dioxide (CO2). Another method is to ignite the gas. If it produces a popping sound or a small explosion, it is likely hydrogen (H2).

What chemical test could be used to confirm that the gas prodced in a chemical reaction is carbon dioxide?
The gas yielded from a chamical reaction should be allowed to pass through clean lime water. If the gas is CO2, it turns lime water milky by formation of CaCO3. This is the confirmatory test for CO2 gas
Is CO2 poisonous?
no, Co2 is not a poisonous gas
What does co2 have to do with science?
co2 is the gas that we exhale. Scientist's think this gas causes global warming. ( plants filter co2 )
How do you test a gas to see if it was carbon dioxide?
Bubbling the gas into limewater is the classic test for CO2. Limewater is a saturated solution of Ca(OH)2. When CO2 is dissolved it reacts to produce insoluble CaCO3 and the solution turns cloudy. Ca(OH)2(aq) + CO2(aq) --> CaCO3(s) + H2O(l) :)
How do you test for presence of carbonate ion?
Reagent: Add dilute Hydrochloric acid [HCl] Inference: Effervescence and a gas which turns limewater milky [CO2 ] Equation: CO32- +2H+ -> H2O + CO2
What gas in in your blood gas?
oxygen and co2
What is a test to show that a gas is carbon dioxide?
Put the gas (CO2) in lime water. If the lime water changes colour, then it means that there is carbon dioxide in the gas depending on how fast the lime water changes colour
What is the fomula of CO2?
Carbon dioxide (CO2) is an inorganic gas.
What is a a property of co2?
CO2 gas is colorless, and it is covalently bonded.
Which gas is used for the preparation of Soda water?
Carbon dioxide or CO2.
