Chemistry - Writing and Balancing Chemical Equations

Extending this syolism to represent both the identities and the relative quantities of substances undergoing a chemical (or physical) change involves writing and balancing a chemical equation. Consider as an example the reaction between one methane molecule (CH 4 ) and two diatomic oxygen molecules (O 2 ) to produce one carbon dioxide molecule (CO 2 ) and two water molecules (H 2 O).

Water softening - Wikipedia

Water softening is the removal of calcium, magnesium, and certain other metal ions in hard water.The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of pluing by reducing or eliminating scale build-up in pipes and fittings.

Carbonate chemistry — Science Learning Hub

Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites.
