Reflection Read and analyze the statement below and answer the corresponding questions in a separate sheet of paper. The air we breathe is composed of nitrogen, oxygen, carbon dioxide, water vapor, and small amount of other gases. Substances which are not primary components of air and present in relatively high concentrations pollute the air. In accordance with the World Health Organization's guidelines in 2020, the air quality in the Philippines is considered moderately unsafe.

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.
