a FIRST PERSON narrator is an I (occasionally a we) who speaks from her/his subject position. That narrator is usually a character in the story, who interacts with other characters; we see those interactions through the narrator's eyes, and we can't know anything the narrator doesn't know. a SECOND PERSON narrator speaks in you..
The heat of the metal determines the color of the sparks. Lithium-Lithium is a metal that is used to impart a red color to fireworks. Lithium carbonate, in particular, is a common colorant. Magnesium-Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework.Oxygen-Fireworks include oxidizers, which are substances that produce oxygen in order for burning to occur. The oxidizers are usually nitrates, chlorates, or perchlorates.he heat of the metal determines the color of the sparks. Lithium-Lithium is a metal that is used to impart a red color to fireworks.

Click to Enlarge. Itâs Fireworks Night here in the UK tomorrow, which means fireworks (obviously), bonfires and sparklers. Weâve looked at fireworks in a previous post, so this time around itâs time to take a look at the chemicals that go into producing sparklers, and their various roles.In sparklers, there are three main components to the composition: a metal fuel, an oxidiser, and a binder.he temperature of the burning sparkler can easily reach between 1000-1600ËC, and the use of additional fuels can also have an effect on this. Regardless of your previous chemistry education, you probably came across the concept of oxidation and reduction reactions.
