Sodium: Na Sodium is an element in the periodic table with the symbol Na. Sodium has an atomic number of 11 and an atomic mass of 22.98977 amu and is an Alkali metal. Sodium was used in ancient times by the Egyptian and Roman civilizations. Egyptians would call Sodium by the name of "natron" and Roman's had a similar name for the element, "Natruim". These names lead to the elements symbol, Na. The naming of Sodium originated from the Arabic word suda (headache). This was used as a cure for headaches during this time in history. However Sir Humphrey David discovered how to make sodium metal in ...

Conclusion. From doing the investigation on rates of reaction I have found that the higher the temperature of a reaction, the quicker the reaction goes at. From my results you can see that at 25c the reaction took 69 seconds compared to 45c, which took 43 seconds. This agreed with my prediction, which was the higher, the temperature the quicker the reaction. The scientific evidence which supports this is the temperature of a reaction is increased this would then increase the rate of reaction. A chemical that is heated will send energies of movement straight to the particles of the chemical. W...

Car accidents can prove to be fatal. However, with the proper safety measures, fatality can be avoided. Seatbelts can save your life, as well as airbags. An airbag is a big that undergoes a chemical reaction to burst out and causes a stop in motion, pillowing you into it. Airbags are complex, and a necessity to life. When two or more cars collide, force is exerted. This force is measured in an electronic sensor in the tunnel of the car. If the car decelerates at more than twenty-eight kilometers per hour, then the ignitor will trigger the gas generator, which will start a chemical reaction in ...
