Experiment In this lab we were asked to observe changes and colors when mixing two or three chemicals together. The actual experiment itself used twelve different pipits and three chemicals I selected from my house. To begin‚ I first gathered everything‚ including the 96 well plate‚ 24 well plate‚ goggles‚ and gloves along with the observations of chemical changes bag. I set it up all on the the kitchen table that had paper towels on it. Next‚ I made my data table so that I could record my reactions

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a
