Save Fred!
During this lab we were tasked with saving Fred, a gummy worm in distress. Basically we had a gummy work (Fred) a life preserver and some paper clips. Fred boat has tipped over and its up to you to save him. You have to move Fred from the top of his flipped boat to the inside with his life preserver, without touching anything, you have to use the paperclips to move him.

Periodic Trends Reactivity - John McC - Matthieu 9/10/14
Purpose
To explore reactivity trends of metals in groups and periods of the periodic table.
Pre Lab Questions
1) Groups are vertical collums of elements with similar properties. Periods are the horizontal rows of elements.
2) Metals are located to the left of the metalloid boundaries .
3) Alkali metals, Alkaline Earth Metals
4) Aluminum
Procedures - Part 1
1) Gather materials, Take to desk.
2) Label your test tubes.
3) Get your CA and MG from Charlene.
4) Put Samples into labeled test tubes.
5) Add enough water to cover sample.
6) Record observation in the table.
Table Part 1
Metal-------------------------Observations-----------------------------------------------------------
Mg Nothing, Falls to bottom doesn't float.
-------------------------------------------------------------------------------------------------------------
Ca Looks like milk (white, very viscous), Some settled on bottom.
-------------------------------------------------------------------------------------------------------------
Part 2 Activity series metals in HCL
1) Obtain samples from Charlene.
2) Get HCL from Charlene.
3) Put samples in labeled test tubes.
4) Add enough HCL to cover sample.
5) Record observations in table.
Metal-------------------------Observations-----------------------------------------------
Mg Exothermic Reaction, Smoke, Disolved.
------------------------------------------------------------------------------------------------
Zinc Exothermic Reaction, Bubbles like crazy, smoking.
------------------------------------------------------------------------------------------------
Tin No Reaction.
------------------------------------------------------------------------------------------------
Post Lab Questions
1) Magnesium is a metal (a solid) it can be found in the planet, made by the universe. Calcium is a man "Made" substance and a powder.
2) Zinc, Magnesium, Calcium, Tin
3) Yes, in most cases elements are organized together depending on ALL similarities this includes relative activity.
4) 9.23 g/cm3
5) Reactivity, moving down increases.6) It stays relatively around the same reactivity.7) Fr, Cs, Na. Ga, Rb, Fr
8) Francium it is at the bottom of the alkali metals the. "Most bottom". Maybe it might be found naturally, deep in the planet but I doubt you would find and exposed francium.
9) Yes they do all accept tin, which didn't react at all.
