Announcements:
We will be having our second quiz next week, test on Thursday, and a party on Friday
Today we did a single replacement reactoins lab. We had four substances: Mg(NO3)2, Cu(NO3)2, Zn(CO3)2, and Ag(NO3)2. We also had three metals: Zinc, Magnesium, and Copper. We tested all three metals reactions in all four substances. Our goal was to put in order the most reactive metal to the least reactive metal. In addition, we know that all chemical reactions between the metals and substances were to be considered single replacement reactions were one element takes another's place. We made a data table to find the most reactive. We found four single replacement chemical reactions and we solved and balanced their outcomes:
Zn+Cu(NO3)2=Zn(NO3)2+Cu
Zn+Ag(NO3)2=Zn(NO3)2+Ag
Mg+Cu(NO3)2=Mg(NO3)2+Cu
Mg+Ag(NO3)2=Mg(NO3)2=Ag
Then we concluded that Magnesium was more reactive than Zinc because it had more violent reactions with the substances. So the order was Magnesium, Zinc, and Copper.
