how would you separate co2, h20, chalk and salt
Collect the CO2 gas. Filter the chalk out of the water. Then evaporate the water, leaving the salt behind.
First to get the CO2 out you put a bag over the bottel and squeeze it out of the bag or most will go out on its own but you will loose some.
Then add more water so the salt can dissolve.
And lastly you use filter to separate the Chalk and the water. And get them by selves.
The Chalk in the filter and the Water in a glass or beaker.
