student performs Experiment 7 using copper wire as the initial copper source and obtains the following data: At the beginning of the experiment, the student weighs out a clean, dry beaker and obtains a mass of 120.4265 g. The student adds the copper wire to the beaker and obtains a mass of 122.4715 g. After performing all of the reactions, the student weighs the beaker containing
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.
