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.

The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. Suppose 48.0mL of dioxygen gas are produced by this reaction, at a temperature of 100.0°C and pressure of exactly 1atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits.
You are given a crushed sample that is a mixture of limestone (calcium carbonate), lime (calcium oxide), and sand. The calcium carbonate, or limestone, is the only material present in the mixture that will decompose when heated. You subject a 6.0685 g sample of the mixture to strong heating and after the sample reaches constant mass (no more mass is lost with additional heating), the sample has a final weight of 3.9247 g. What is the percentage of calcium carbonate present in the original mixture? (MW of calcium carbonate = 100.1 g/mol) Equation for reaction = CaCO3(s) -> CaO(s) + CO2(g).
