In the image below, you will see four laboratory spectra for known elements as well as the sample spectra for two unknown objects. Use the laboratory spectra to identify the chemical composition of both unknown spectra: Spectra A and Spectra B. For each unknown spectra, write out the chemical composition you determined and support your answer by explaining the evidence from the spectra
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
