Chemistry
Fourth Award
Objectives/Goals When a copper wire and a zinc nail are inserted into a fruit, electric current can be measured with a voltammeter flowing between the metals. The goal of my experiment was t…
Chemistry
Objectives/Goals The main purpose of this experiment #I#m Melting# is to find a substance that would melt ice just as fast as salt, yet at the same time not harm any vegetation or concrete.…
Chemistry
Objectives/Goals This study was on the kinetics of the zinc-copper voltaic cell. The goal was to determine the order of the reaction with respect to Cu2+ concentration, which was ultimately…
Chemistry
