Dilution and Concentration of Solutions
Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...
Curated OER
Chemistry
In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...
