Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass

SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for
