Use the information below to answer the following question(s). Matter can be classified as an element, a compound, or a mixture. The elements sodium (Na) and chlorine (l) react with each other to form the compound sodium chloride (Nal), also known as table salt. The reaction between sodium and chlorine releases energy. This energy causes the temperature of the substances in the reaction to increase. When table salt dissolves in water a solution is formed, which is a type of mixture. Which list correctly describes the gases in containers R, S, and T?. R = element, S = compound, T = mixture. R = compound, S = element, T = mixture. R = element, S = mixture, T = compound. R = mixture, S = element, T = compound Which of these changes must happen for elements to become a compound?. elements are heated. a gas becomes a liquid. elements dissolve in water. chemical bonds form between atoms page 4 toms, Elements, ompounds and Mixtures
