Reducing Our Carbon footprint

http://www.jpmorganclimatecare.com/climate/low-carbon-living/#home
Electricity Conservation :
Switch to energy saving light bulbs


  • Electric tumble dryers use a huge amount of energy. If it’s a nice day dry your clothes outside or even inside if it’s not so nice.







  • When using a washing machine ensure there is a full load and turn down the temperature.







  • Take your phone charger out of the wall. It uses energy even when it’s not charging your phone.






  • Food :


  • Take your phone charger out of the wall. It uses energy even when it’s not charging your phone.






  • Driving :


  • If you're stuck in a jam, switch the engine off if you expect to be there for more than a minute or two. Cutting the engine will save fuel and reduce emissions.


  • Get your car serviced regularly to keep it running efficiently.







  • Plan your journeys to avoid congestion, road works and getting lost.

    CINCO REACTIONS!

    Synthesis: Synthesis is adding two elements together to equal one new element. C+D=CD

    Decomposition: The opposite of synthesis. Break down the elements to separate the compound element. CD=C+D

    Single-Replacement: A metal replaces a metal, and a nonmetal replaces a nonmetal. F+GH turns into FH+G.

    Double-Replacement: The same rules follow as single-replacement. RD+MC turns into RC+MD

    Combustion: all substances in a compound are combined with oxygen, combustion means burning. Heat is easily produced, but can be easily distinguished. CxHy + O2 --> CO2 + H2O

    Defenitions

    Synthesis : is a reaction in which two or more substances mix to give a new compound .
    Decomposition : separation of a substance into two or more substances that may differ from each other and from the original substance .
    Single-Replacement : a type of oxidation-reduction chemical reaction when an element or iron moves out of one compound and into another .
    Double-Replacement : a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound .
    Combustion : chemical reactions between a fuel and an oxidant mixed by the production of heat and conversion of chemical species. The release of heat can result in light or a flame .

    The Chemistry Magic Show ,


               The experiments today went as good as they should have. All the scientists started of in a line in the back of the stage. Whenever it was the time for each experiment the scientist would go up , and perform it. We had two different experiments and one was performed with the lights on and one was performed with the lights off. For the Halloween Reaction, the lights were on so everyone could see the transformation. It was time for the experiment and Brittney nervously approached the table. She was worried the chemicals we mixed would not work, and it came out black just as it should have. The reaction happened fast so that proves that we used a smaller volume of solution B. For the glow juice, the lights were on for a moment so Brittney and Felicia could carefully mix the solutions, but after they were quickly mixed, the lights were turned off. Felicia had to stand on a chair so she could pour the chemicals in a tube that swirled around a small pole. She hesitantly did and there was a glow, but it wasn't bright. It glowed all down the tube, until it got to the bottom. The magic show came out better than we thought.



    The black Liquid is the outcome of the halloween rxn.

    Glow Juice .

    luminol
    3 percent hydrogen peroxide.
    2 large mixing bowls .
    distilled water
    sodium carbonate
    copper sulfate pentahydrate


    OK, first step: Take half the water—one liter—and add to it the hydrogen peroxide. We're just diluting the peroxide, basically. Set this bowl aside for later.

    Now, in the other bowl, dump the rest of the water and 4 grams of sodium carbonate, which helps all the other chemicals mix together better.

    Add to the sodium carbonate mixture 0.4 grams of copper sulfate pentahydrate. It’s going to help light up the luminol, which is looking to steal electrons from metals—in this case, the copper in the copper sulfate . Luminol can only dissolve in highly alkaline solutions—11.8 pH.

    And now we carefully add 0.2 grams of luminol to the sodium carbonate/copper solution. And here we are with a fully prepped solution, just waiting to glow.

    Now let's return to the diluted hydrogen peroxide and add it to the luminol solution. The hydrogen peroxide replaces two of luminol’s nitrogen atoms with oxygen, producing a bunch of electrons so excited that they kick out a blast of photons. That’s the glow in our glowstick!


    ps .... dont drink it !


    The glow juice was not very hard to prepare. We just had to get two bowl for 2 different solutions. In bowl one we had water and hydrogen peroxide. In bowl two we had  4 grams of sodium carbonate and 0.4 grams of copper sulfate pentahydrate. while demonstrating it , we will have to mix the 2 solutions and put it into one beaker, and mix the third solution we cam up with , with luminol to make it glow.
