Carbon dioxide scrubber - Wikipedia

A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2).It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft, submersible craft or airtight chaers.Carbon dioxide scrubbers are also used in controlled atmosphere (CA) storage. They have also been researched for carbon capture and

Calcium metal reacts readily with water according to the equation: Ca + 2H2O Ca(OH)2 + H2 If 3.23 g of Ca react with 2.33 g of H2O, what is the limiting reactant in this reaction? (Be sure to show your work.)

Aluminate Phase - an overview | ScienceDirect Topics

The hydration of the system C 3 A-CaCl 2-CaSO 4 ·2H 2 O shows that the calcium chloride primarily accelerates the reaction between C 3 A and gypsum. Sulfate reacts first followed by reaction of C 3 A and chloride after the gypsum has been used up. Calcium chloride appears to stabilise the formation of trisulfoaluminate (ettringite).

However, of the individual components of distillation waste, only Ca(OH) 2 can react with CO 2 according to Equation (4). Calcium chloride, although its concentration in the liquid is still high, does not react with carbon dioxide. This is because CaCl 2 is the salt of a strong acid while carbonic acid is a weak acid.

Hard water - Wikipedia

Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is
