Introduction

FIREWORKS Fireworks were first developed in China and used by the Chinese on any event (e.g. birth, death, wedding, new year). Some scholars say fireworks were developed in the Sui and Tang Dynasties (581-907), but others say that there were no fireworks until the Northern Song Dynasty (10th century). HOW DO FIREWORKS WORK? Fireworks are made up of several components: * Gunpowder - a mixture composing of: 75% Potassium Nitrate (KNO3), 15% Charcoal (Carbon), and 10% Sulphur. ...read more.

Middle

e.g. 14cm long and 2cm in diameter. The fuse is lit by a match and then the fuse burns rapidly into the core of the rocket where it ignites the gunpowder walls of the interior core. Gunpowder contains potassium nitrate, which is the most important ingredient. This is because of the molecular structure of KNO3, which is made up one potassium atom (K), one nitrogen atom (N), and three oxygen atoms (O3). ...read more.

Conclusion

The whites and golds are made with mixtures of iron, magnesium, and aluminium and using copper salts produces blues, but this isn't all that happens. One way is when the shell explodes the flames (heat) gives the electrons of the atoms extra energy causing the electron to jump to a higher energy level (or shell). When the electrons cool down they get rid of this extra energy in the form of a light particle (each element give a different light of the light spectrum) and the electron moves back down to its original energy level/shell.

  2. Investigating how concentration affects rate of reaction

    For this reason, I decided to conduct experiments testing two more concentrations within the range of the other four, thus making up for the two concentrations I had not been able to investigate. The results for these extra concentrations are shown below: Concentration of Sulphuric Acid (mol/dm-3)
