Why is the pH of deionized H2O often less than 7.0?
Because when it is exposed to air, the CO2 will effectively lower the pH
What happens when copper utensils are exposed to prolonged atmospheric air?
When copper is exposed to moist air for a long time, it acquires a dull green coating. The green material is a mixture of copper hydroxide and copper carbonate. This film called 'verdigris' protects the underlying metal from further damage. 2Cu + H2O+CO2 + O2 Cu(OH)2 + CuCO3
What happens when carbonic acid is unstable?
Basically the CO2 releases into the air and water is left. Its unstable because CO2 is a gas at room temp.
What happens when Mathane burns in air?
MEthane or CH4 with complete combustion will turn into CO2 and H2O The formula for complete combustion of methane: CH4 + 2O2-> CO2 + 2H2O
Why is air consider as a mixture while it cannot be separated physically?
It can be separated physically. By gradualy cooling air the gases are liquified each at their own teperature. The end result is solid CO2 (Cardice), liquid nitrogen and liquid oxygen.
What happens when bromthymol blue is exposed to CO2?
According to our experiment, CO2 was released to the BTB, it became like color yellow-green.
What happens if you puncture a pressurised can?
If there's any CO2 in it at the time, it all leaks out. As the gas escapes, it expands, cools, and the pressure in the canister drops.
For a paintball rifle is CO2 better than compressed air?
No compressed air would be better for accuracy as well as your gun. Its like co2 but at a higher pressure with cleaner air and no liquid that can damage your paintball marker.

Solid dissolves in gas?
oxygen \
What happens to air in a balloon?
it slowly leaks out of the balloon, to equalize oxygen and Co2 levels.
What happens when carbonic acid is unstable?
Basically the CO2 releases into the air and water is left. Its unstable because CO2 is a gas at room temp.
What happens when ZnCO3 is heated in the absence of air?
ZnCO3, when heated in the absence of air, decomposes to give ZnO and CO2. I think this is the answer.
What happens to the freezing point of water when the air pressure is low?
It evaporates, because when it is low there is not enough CO2 to condense the air.
Which does potassium hydroxide bond with to form a solid CO2 O2 H2O Air or Glue?
Potassium hydroxide will bond with CO2 to form solid sodium carbonate and liquid water.
What happens if you use co2 with your paintball gun?
If your gun is meant to run on CO2, then it will function well. If it is not, then it will jam up when the liquid gets insides until the gun completely jams up.
