The average titration figure is then used to standardise (determine the specific concentration of) the Hydrochloric acid solution.

    Procedure: 
    • Set up apparatus as shown.
    • Add a few drops of phenolphtalein indicator to the NaOH in the conical flask. (note colour)
    • Allow the HCl to flow from the burettes into the NaOH in the conical flask.
    • Add the HCl drop by drop until the solution in the conical flask changes colour. (note colour)

The new findings come after researchers took a new look at the factors that limit human speed. Their conclusions? The top speed humans could reach may come down to how quickly muscles in the body can move.
    Factors that influence speed:
    • Wind resistance
    • Stride frequency
    • Contractile speed limits of the muscle fibers
    "Our simple projections indicate that muscle contractile speeds that would allow for maximal or near-maximal forces would permit running speeds of 35 to 40 miles per hour and conceivably faster," Bundle (one of the scientists who carried out this report) said.

This explains why a rock will sink while a huge boat will float. The rock is heavy, but it displaces only a little water. It sinks because its weight is greater than the weight of the small amount of water it displaces.

It should emulate sounds of pleasure and affection instead of distress. Finally, scientist believe that the main reason that you like a song is because of what it reminds you of. You need two of the factors listed above to have a good song. So if there was a song that is really sad but it it has rhythm and it reminds you of your best friend you still like it.]]> 2017-05-15 18:43:21 UTC https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/171926102 Why are aeroplanes used in music videos so often? 13jdolan_occ https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/171932122 There are many reasons music videos are shot in aeroplanes. Aeroplanes do not offend anybody, so people don't have any problem watching the video. When you watch a video which is inside an aeroplane you associate it with flying so you get excited as anyone would when they are flying. Thirdly, in some cases air hostesses are used because they are easy to look at and make people want to watch the video. Foo Fighters, Busted, Britney Spears and many more have all had music videos from the inside of a plane for at least one of these reason.]]> 2017-05-15 19:07:59 UTC https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/171932122 13jdolan_occ https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/171934362 2017-05-15 19:19:08 UTC https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/171934362 What part of your tongue tastes what 13jdolan_occ https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/171934811 2017-05-15 19:21:18 UTC https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/171934811 Salts and their colours 13jdolan_occ https://padlet.com/13jdolan_occ/vhyfnonn3wwq/wish/172033268 Strontium Chloride: Red
