Lab Safety:
* Chemical Safety: watch out for any spills, keep the area clean * Heat Safety: stay at a safe distance from the flame
* Sharp Object Safety: take caution when working with magnesium wire * Safety glasses: in case of splashes from the chemicals * Horseplay will not be tolerated

Purpose: The purpose of this lab is to find the enthalpy of combustion of Magnesium. In other words the purpose of this experiment is to determine the enthalpy of formation of magnesium oxide. Background Information:

Sparklers are a type of handheld firework that burns for about a minute while giving off little sparks. They are composed of two fuels, an oxidizer, and pyrotechnic colors (to add visual interest). There’s also a compound that holds them together, either dextrin or nitrocellulose. However, the most important component to a sparkler is the magnesium. The function of the magnesium in sparklers is to provide the bright light to the sparkler. When magnesium is burned it gives off this bright white light, which makes the sparkler glow. Certain regulations to sparklers and firecrackers exist because of how dangerous they can be. According to the American Pyrotechnic Association, in the state of Georgia, a person must be 18 or older to purchase any firework. Also, Georgia does not allow any firework that explodes or shoot into the air, however sparklers, poppers, or any noisemaker is allowed. Numerous accounts of accidents from sparklers occur every year because sparklers burn at very high temperatures and very quickly. During the month of July there was a higher accident rate. There were 1,100 cases of children getting burned from sparklers, and 1,100 cases of fireworks also. MgO(s) + 2HCl(aq) = MgCl2(aq) + H2O(l) and also Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g). This reaction would be exothermic because it is releasing heat and...
