26 Fireworks Do you enjoy watching fireworks? Do you like their colorful sparks and loud noises? Fireworks start out as hollow cardboard tubes filled with gunpowder. A fuse sticks into this gunpowder. The fuse is a thick cotton string. It's been soaked in saltpeter. When a flame lights the fuse, it burns the gunpowder. This makes the rocket shoot into the air. Then the gunpowder lights a smaller packet of gunpowder. This blows up the cardboard tube. It ignites tiny firecrackers at the top of the rocket, too. What makes the different colors? Small amounts of chemicals are added to the gunpowder. Sodium makes yellow sparks. Copper makes blue sparks. Charcoal gives the fireworks sparkling tails. Fireworks are not just pretty. They are dangerous. If they blow up near you, you i can be badly hurt. That's why some states won't let stores sell fireworks. That way, ni only experts can set them off. Fireworks have other uses, too. You may : have seen red flares on a road around an. accident. They are a different kind of firework. They burn for a long time and do not blow up. Check Your Understanding 1. Which chemical makes yellow fireworks? a. sodium c. copper b. charcoal d. calcium

Bonus Knowledge

Sodium is the magical element that turns fireworks into dazzling yellow bursts! When it reacts with the heat of the burning gunpowder, it ignites and produces that bright and cheerful golden glow that we all love to see in the sky. Aside from dazzling displays, fireworks also play a critical role in celebrations worldwide, from New Year's Eve festivities to the Fourth of July in the United States. It's fascinating how they bring communities together, sparking joy and amazement as people gather to watch brilliant colors illuminate the night sky, creating unforgettable memories. Just remember to enjoy their beauty safely!

The human body burns glucose \( \left(\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}\right) \) for energy according to this chemical reaction: \[ \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+6 \mathrm{O}_{2} \rightarrow 6 \mathrm{CO}_{2}+6 \mathrm{H}_{2} \mathrm{O} \] The products of the reaction are carbon dioxide \( \left(\mathrm{CO}_{2}\right) \) and water \( \left(\mathrm{H}_{2} \mathrm{O}\right) \). Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500 . iml. which is typically enriched to \( 4 \% \mathrm{CO}_{2} \) and \( 5 \% \) water vapor by volume.

M A. B. Figure 3 - Diagram of two waves. Which is of higher energy, wave " \( A \) " or wave " \( B \) "? \( \qquad \) How do atoms produce visible light and how is it related to atomic structure? The current model of atomic structure includes the presence of a nucleus (consisting of protons and neutrons) surrounded by electrons. Experimental evidence, including the analysis of light emitted from excited atoms, has led to the hypothesis that electrons in an atom exist at certain allowable locations away from the nucleus, corresponding to certain energy states or energy levels. Electrons closer to the nucleus are considered to be lower in energy than those further from the nucleus. Electrons can absorb energy from a flame or electric discharge, but only in packets that contain the exact amount of energy necessary to allow the electron to move farther from the uucleus into a higher energy level/energy state. When this happens, we say that the atom is in an excited state. When the electron returns to a lower energy level, it emits the previously absorbed energy in the form of packets of light called photons. These photons/packets of light ave a specific wavelength and energy equal to the difference between the two energy levels. Why does the light emitted from an excited neon atom look red to the human eye and iulticolored when viewed through a prism or spectroscope? In a given atom, many xcited states are possible due to the existence of a number of energy levels. When light is nitted by excited atoms, a variety of energies of light are released as the electrons return to eir lowest energy level. The naked eye perceives the sum of these emissions as colored light, \( y \) red or blue. For example, the color of fireworks is the sum of the various excitations of ectrons in metallic salts. When this emitted light is passed through a prism or a diffraction grating in a spectroscope ne spectrum is seen. Each line in the line spectrum corresponds to a packet of light of a ticular energy. This packet of light is emitted by the excited atom when electrons fall to low rgy levels from the excited state. Each element has its own unique line spectrum due to erences in the possible energy level transitions in atoms of different elements. The analys ne light emitted from atoms is used to determine the identity of elements in water, the sta many other types of matter.
