Mass balance - Wikipedia

2019-4-23 · A mass balance, also called a material balance, is an appliion of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of

Chemical Equations (previous version) | Chemistry

In the example seen above, 3O 2 had to be added to the right side of the equation to balance it and show that the excess oxygen is not consumed during the reaction.In this example, methane is called the limiting reactant. Although we have discussed balancing equations in terms of nuers of atoms and molecules, keep in mind that we never talk about a single atom (or molecule) when we use

Water Hardness - chemistry.wustl.edu

2014-9-29 · This precipitate, known as scale, coats the vessels in which the water is heated, producing the mineral deposits on your cooking dishes. In small quantities, these deposits are not harmful, but they may be frustrating to try to clean. As these deposits build up, however, they reduce the efficiency of heat transfer, so food may not cook as evenly or quickly in pans with large scale deposits.
