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.

![**Chemical Structure:**
- **Formula:** CH₃CH₂CH₂CH₃
- **Name:** Butane (Substance I)
**Description:**
Butane is a straight-chain alkane composed of four carbon atoms and ten hydrogen atoms. It is a colorless and easily liquefied gas. Butane is primarily used as a fuel in lighters and portable stoves and is a key component of liquefied petroleum gas (LPG).
This structural formula represents a linear arrangement of carbon and hydrogen atoms, showcasing its saturated hydrocarbon nature.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F53b194e6-8e1d-4197-8203-a99ce3110a41%2Fac38531e-99bf-4f70-aba6-e5d9d8f96cfe%2Ft19ty9e_processed.png&w=3840&q=75)
![The image displays the structural formula of a hydrocarbon labeled "Substance II." It consists of a central carbon atom (C) bonded to four groups: three methyl groups (CH₃) attached in different directions (left, right, and above) and one hydrogen atom (H) attached directly below the central carbon. This structure represents a branched alkane, specifically 2,2-dimethylpropane, also known as neopentane.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F53b194e6-8e1d-4197-8203-a99ce3110a41%2Fac38531e-99bf-4f70-aba6-e5d9d8f96cfe%2Fqkznoz_processed.png&w=3840&q=75)
