Metal Reactions.

 Metal + Acid

Equation - Metal + Acid >>> metal salt + hydrogen

Method - Get a splint and light a Bunsen burner, then you need to get 2ml of Sulfuric acid and put it in a test tube, then put a small piece of metal in the test tube, the metal will dissolve and the test tube will heat up, after that you need to put a boiling tube on top of the test tube and put the test tube inside, wait 1 minute and light the split. then with the splint you need to lift up the big boiling tube, keep it upside down, and put the splint inside the boiling tube, it will make whistle or pop sound.

When we had done the steps to make the whistle, Cody put the splint inside the boiling tube and it made a very loud whistle sound. this experiment was fun because there wasn't a lot to do, but the stuff we had to do was easy. if we were to do this experiment i would like to add more acid and a lot more metal to try and make the sound pop / whistle as loud as possible.

Making a Metal Oxide

Method - Light your Bunsen burner, Hold the piece of magnesium in the scissor tongs but make sure you are holding the very end of the magnesium piece. hold the magnesium over the fire for about 3 seconds in the middle of the flame, not the top, not the bottom, directly in the middle, it should light on fire, that's when you should look away, and just look at it from the corner of your eye, if you look directly into it, it  can permanently damage your eyes.

Testing for the presence of Oxygen

Method - Light the Bunsen burner and add the manganese dioxide to the boiling test tube, add 2 millilitres of hydrogen peroxide. then what you need to do it light the splint for a few seconds and blow it out, the splint will still be hot and glowing, then you need to put the splint in the test tube, not in the hydrogen peroxide but in the middle, and the splint will relight

Metal Carbonate + Acid >>>>>> Metal Salt + Water + Carbon Dioxide

                                      CaCO3          2Ha                 CaA2            H2O            CO2

Equipment - Two Boiling tubes, Delivery Tube and Bung, Bunsen Burner, Test Tube rack, Wooden Splint, a bottle of acid, Small amount of metal carbonate, Test tube tongs, Safety Glasses.

Method - Light your Bunsen Burner and add a tiny pea sized amount of  metal carbonate into one of the boiling tubes, place this boiling tube into a test tube rack, make sure you have the bung and delivery tube ready. add 5ml of acid to the boiling tube, hold the other boiling tube with the tongs and capture the gas, when you think the tube is full your lab partner will light a wooden splint, then put the splint into the test tube and see what happens.
