SUPER LAB AWAAAAAYYYY!!!!

TODAY WAS A SUPER EPIC LAB NO JOKES. What did we do? Well go read lab 5b in your workbooks noobs. Lazy? Fine. Well anyway we did 7 experiments. These experiments were to look at different types of chemical reactions(ex. synthesis, single replacement, etc. Anway the first experiment required us to...


EXPERIMENT 1

take 6cm of copper and hold in on the hottest part of the flame for a few minutes. The copper turned pink surprisingly and it took a while to notice any change

EXPERIMENT 2

Place a nail into a test tube and add copper sulfate so that half the nail is covered. This was a unique experiment. In the begining it seemed as if nothign happend but soon half of the nailed (the part covered by the copper sulfate) turned pink. After 15 minutes we removed the nail and we were surprised to see that the WHOLE NAIL turned pink with splotches of red. Really cool.

EXPERIMENT 3

Pute solid copper sulfate PENTAhydrate into a test tube and heat it for a long time over a bunsen burner. Just like a previous experiment with a hydrate, this leaves over a coloured white sand with white flake remnant instead of a blue powder

EXPERIMENT 4

We add water to our result from experiment 3. The result, unexpectedly, turns back to normal after rehydrating it after it evaporated all its h2o.

EXPERIMENT 5

fill test tube 1/4 full with calcium chloride. Fill 2nd tube with sodium carbonate. Then mix them together. I thought something totally awesome would happen, and well it turned to a milky white solution....COOL.

EXPERIMENT 6

cover mossy zinc with hydrochloric acid. This is quite interesting actually. When added the solution continually keeps bubbling and rises. It keeps on doing this for over 20 minutes which surprised me. This reaction can go on for a looooooooong time.

EXPERIMENT 7

Half fill the tube with hydrogen peroxide and add a small amount of manganese oxide as a catalyst. THEN YOU HAVE TO QUICKLY light a match and stick it. IT ACTUALLY IGNITES! TRUE DMG AND OVER TIME OMFG. LIKE BAM. LIT. A SPARK FROM THE GAS, TOTALLY AWESOME....NO ONE WAS BURNED THOUGH....we tried to imitate this twice but .....no it was a one timer....

EXPERIMENT 8!!!!!!!!!!!!!!!!!!

THE MOST EPIC EXPERIMENT EVAR

MIX EVERYTHING TOGETHER AND SEE WHAT HAPPENS

BEFORE: EMPTY TUBE AND MANY MANY MANY THINGS

DURING: MIX EVERYTHING TOGETHER AND IT STARTS TURNING DARK GREEN

AFTER: IT TURNS BLACK BUT SOME SAID IT WAS DARK GREEN NOT BLACK O WELL

This is the hydrate experiment we did without the calculations he did
