Laboratory Experiments for Chemistry: The Central Science 12th Edition by Theodore E. Brown, John H. Nelson, Kenneth C. Kemp and Matthew E Stoltzfus comprises 43 finely tuned experiments chosen to introduce college students to basic lab strategies and as example core chemical principles. You can even customize these labs via Catalyst, our custom database program.
Textual content references to the corresponding sections have been added. All experiments have been carefully edited for accuracy, security, and cost. New "Give it Some Thought" (GIST) questions help the coed in understanding the ideas exemplified by the experiment New experiments regarding equilibrium thermodynamics and crystalline solids have been added. More helpful hints within the Annotated Teacher's Edition (AIE) have been added.
There is a information on find out how to maintain a lab report notebook. Safety and waste management are covered in greater element, and lots of pre-lab and put up-lab questions have been updated. The labs can be custom-made by way of Catalyst, Pearson's customized database program.
