CHEM 121 FINAL EXAM QUESTIONS AND ANSWERS 100% PASS kinetic molecular theory - Correct Answer ️️ -all matter is made of tiny particles that are constantly moving fundamental particle - Correct Answer ️️ -take a macroscopic object and divide it repeatedly. Eventually you have a particle, which, if further divided is no longer the original substance. This smallest piece of the substance is called... h2o molecule - Correct Answer ️️ -the fundamental particle of water is what? at...

Title: Chemical Reactions Purpose: Observe different kinds of chemical reactions and the results. Six tyles of simple chemical reactions and reversible reactions Procedure: 1. Combine AgNO3 (silver nitrate) and HCl (hydrochloric acid) in test tube. White solid forms - AgCl (silver chloride) 2. Put stopper on and invert to mix. Double displacement reaction. 3. Combine KI and Pb(NO3)2 - creates a yellow liquid (used to be used in paints - caused lead poisoning) 4. Acid/Base Double displac...

Title: Bonding and Properties Purpose: Study the infrared spectra and physical properties of molecules to determine what kinds of intra-molecular bonds are present within the molecules and what kinds of intermolecular bonds are present between the molecules. Procedure: 1. Add potassium chloride (ionic) to water in a test tube. Shake tube so potassium chloride dissolves. 2. Add pentate to test tube of water. Shake to see if it dissolves in the water. 3. Add normal propyl chloride to test t...
