Balancing Chemical Equations | Representing …

If the equation is not balanced, change the coefficients of the molecules until the nuer of atoms of each element on either side of the equation balance. Check that the atoms are in fact balanced. (we will look at this a little later): Add any extra details to the equation e.g. phase syols. Worked example 1: Balancing chemical equations 1

What Are Chlorine Generators and Salt-Water Pools?

Chlorine generators can help fight against waterline scum build-up. They create a better, healthier swimming experience for most people. It isn''t necessary to handle or buy chlorine, and, if the unit is functioning correctly, chlorine residual will always be present in the pool, eliminating algae.

What Is the Chemical Formula for Calcium Carbonate

Calcium carbonate is a common constituent of rocks on Earth, and it is the main component of the shells of marine animals and snails. It releases carbon dioxide in reaction with strong acids. It decomposes into carbon dioxide and calcium oxide when heated up to temperatures above 1,544 degrees Fahrenheit.

The Chemistry of Acid Rain - lardbucket

2013-9-7 · The English chemist Robert Angus Smith is generally credited with coining the phrase acid rain in 1872 to describe the increased acidity of the rain in British industrial centers (such as Manchester), which was apparently caused by the unbridled excesses of the early Industrial Revolution, although the connection was not yet understood. At that time, there was no good way to measure hydrogen
