If theirs more than can safely be present than yes
There should be minimal to no carbon dioxide in root beer when it is properly sealed and stored. Any bubbles or carbonation present in root beer are typically a result of the carbonation added during the production process.
Carbon dioxide itself is not warm or cold, as it is a gas. However, it can contribute to warming the Earth's atmosphere when present in high concentrations, as it is a greenhouse gas that traps heat from the sun.
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.
Magnesium will actually decompose when heated to form magnesium oxide and carbon dioxide. This is a common chemical reaction where magnesium reacts with oxygen from the air to form magnesium oxide, and if there is any carbon present, it can also react to form carbon dioxide.
The product of carbon being burnt is carbon dioxide, when it is burnt in excess of oxygen. Carbon dioxide is colorless and basically odorless, but it can be determined by passing the gases into a solution of limewater. This will become milky, as calcium carbonate would be produced in the presence of carbon dioxide.
"Dry ice" is simply frozen carbon dioxide - which is not a particularly dangerous substance. The only danger is that, as with any gas, if there is too much carbon dioxide in the air, it may displace oxygen - in other words, you would have too little oxygen, simply because it is "diluted" by the carbon dioxide. Just leave it outside and let it evaporate.
It is possible to breathe in carbon dioxide because if you smoke, you will breathe in carbon dioxide.
Any burning (oxidation reaction) produce carbon dioxide.
"Hydrocarbon" means something that contains only carbon and hydrogen. Coal is mainly carbon with small amounts of other materials. There are certainly hydrocarbon compounds present in coal, but for the most part it's probably more correct to think of it as an impure form of carbon.
Hydrogen, carbon, and oxygen
No: Hydrogen and sulphuric acid do not contain the element carbon, and no chemical reaction can have any element as part of the products that was not present in at least one of the reactants.
No, ammonia does not turn limewater milky. When ammonia reacts with limewater (calcium hydroxide solution), it forms a clear solution without any visible change. The milky appearance in limewater is typically caused by the precipitation of calcium carbonate when carbon dioxide is bubbled through the solution.
