Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors‚ produce gases proving if the solutions are soluble or insoluble. Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row‚ into seven of the wells‚ and so on with the other three Nitrates. I then cut off

Chemistry 2202 Review Final Exam Chapter 2: The Mole 1. Isotope – atoms of an element that have the same number of protons but different numbers of neutrons. Ex. The three forms of oxygen are called oxygen-16‚ oxygen-17‚ and oxygen-18. They all have 8 electrons and are written as 16/8 O (8 protons + 8 neutrons)‚ 17/8 O (8 protons + 9 neutrons)‚ and 18/8 O (8 protons + 10 neutrons). 2. 3.
