Dearest all,
Merry Xmas! & Have a blessed year ahead!
As promised, Sean has completed this X'mas present for everyone. This present will allow anyone to be a master in BALANCING. Yes! I mean Chemical Equations :)
You can download this video for f*ree!

Tips for O Level Chemistry - Metal Reactivity Series
Yoz All O Level takers,
Hope things are going fine on your side.
Recently, i have Chemistry questions asking how to memorise the Metal Reactivity Series - in order to answer numerous questions that require the knowledge of the series. I certainly believed that school teachers would have improvised their own ways of helping you to memorize the series. Some are easy while unfortunately others are tough in way (for some that dont feel connected).
My suggestion is to come up with your own "Songs" or "Riddles" in order to easily memorise it. If you have no clue on how to do it, and do not like the one given by your teachers, perharps you want to try this one out:
Potassium -> Please
Sodium -> Send
Calcium -> Charlie
Magnesium -> Monkey
Aluminium -> And
Zinc -> Zebras
Iron -> In
Lead -> Large
Copper -> Cages
Mercury -> Most
Silver -> Securely
Gold -> Guarded
Hope you will find it useful.
All the Best,
Sean

Chemistry Phenomenons - Guano Kills The Bridge
Learning Chemistry is easy when you show aptitude and interest in the subject. Chemistry is happening around us everyday - all the phenomenons.
Below i would like to share with you on a Chemistry Phenomenon that i came across in TODAY papers dated 25th Aug 07.
Title: Did Pigeon Poo Weaken Fallen Minnesota Bridge?
I almost LOL when i read the title of this article. Interesting isn't it. Corny in a way. But after catching my breath and reading through - it is no corny anymore, it is based on scientific knowledge.
Inspectors searching for causes of the collapse of a Minnesota Bridge this month that killed at least 13 people have identified pigeon droppings as a possible factor. It is thought the build-up of Guano over many years could have speeded up the rusting of the steel beams in the eight-lane bridge, which collapsed into the Mississipi River on Aug 1.
Structural engineers had been aware of the problem as early as 1987, when inspectors noted a coating of Guano on the inside of some of the steel girders. Pigeon droppings contain Ammonia and Salt, which, when combined with rainwater, can lead to tiny electrochemical reactions that rust the steel."Over a long term, it might in fact cause structural weaknesses." Mr Neal Langerman, of the prestigous American Chemical Society (ACS) said.
The authorities can point to efforts to contain the problem, when screens were put up to prevent pigeons from nesting in some if the openings in the structure. But the build-up of Guano is thought to have continued on the other parts of the bridge.Guano is just one of the factors that Inspectors are considering as they seek to prevent a repeat of the catastrophe in other ageing bridges in the United States.
Here is what i call CHEMISTRY - The World of Wonders!
Enjoy,
