In chemistry lime water can be used to test the presence of carbon dioxide because lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate. It is used to show how Limewater + Carbon Dioxide Chalk(/Limestone) + Water :
Ca(OH)2(aq) + CO2(g) CaCO3(s) + H2O(l)
NB: If too much carbon dioxide comes into contact with the cloudy limewater, it will cause the calcium carbonate precipitate to redissolve to form soluble calcium hydrogencarbonate.
CaCO3(s) + CO2(g) + H2O(l) Ca(HCO3)2(aq)
If you want to remove large amounts of CO2 there are other more robus methods (but less useful as a test)
If you are refering to photosythesis.
The fixation or reduction of carbon dioxide is a light-independent process in which carbon dioxide combines with a five-carbon sugar, ribulose 1,5-bisphosphate (RuBP), to yield two molecules of a three-carbon compound, glycerate 3-phosphate (GP), also known as 3-phosphoglycerate (PGA). GP, in the presence of ATP and NADPH from the light-dependent stages, is reduced to glyceraldehyde 3-phosphate (G3P). This product is also referred to as 3-phosphoglyceraldehyde (PGAL) or even as triose phosphate. Triose is a 3-carbon sugar (see carbohydrates). Most (5 out of 6 molecules) of the G3P produced is used to regenerate RuBP so the process can continue (see Calvin-Benson cycle). The 1 out of 6 molecules of the triose phosphates not "recycled" often condense to form hexose phosphates, which ultimately yield sucrose, starch and cellulose. The sugars produced during carbon metabolism yield carbon skeletons that can be used for other metabolic reactions like the production of amino acids and lipids.

Lithium hydroxide. Weight for weight more efficient than other absorbants. NASA approved.

flowers have eco-friendly chemical factories. They use the flexibility from the sunlight alongside with water to form a chemical reaction that provides off oxygen. there is not any different chemical reaction in the international that makes oxygen as quickly as photosynthesis.
