A scientist has three unlabeled samples of pure metals. He wants to determine the identity of each metal. a. Identify which one of the following properties the scientist should use to determine the identity of the pure metal in each sample: color, melting point, mass, or volume. b. Explain why the property you identified in part (a) can be used to determine the identity of the pure metal in each sample. The scientist cuts each of the samples of pure metal into two smaller pieces. c. Is the property that is used to determine the identity of the metal affected when each sample is cut into two pieces? Explain your answer The scientist can also use density to determine the identity of the pure metal in each sample. d. Describe how the scientist can determine the density of the pure metal in each sample.

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.
