Combustion of hydrocarbons such as methane (CH¼) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can rap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about vhether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous methane into gaseous carbon dioxide and gaseous water. O-0 On x10 2. Suppose 0.200 kg of methane are burned in air at a pressure of exactly 1 atm and a temperature of 15.0 °C. Calculate the volume of carbon dioxide gas that is produced. Be sure your answer has the correct number of significant digits. olo

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.
