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.
![**Balancing Redox Reactions in Basic Solutions**
**Problem Statement:**
Balance the following redox reaction in a basic solution:
\[ \text{Sb}_2\text{O}_3(s) + \text{NO}_3^-(aq) \rightarrow \text{H}_3\text{SbO}_4(aq) + \text{NO}(g) \]
**Guidelines:**
- Identify the oxidation and reduction half-reactions.
- Balance atoms and charges separately for each half-reaction.
- Combine the balanced half-reactions and ensure the number of electrons lost equals those gained.
- Adjust with OH⁻ ions to balance the basic solution.
- Verify that mass and charge are balanced in the final equation.
This approach will help you achieve a balanced equation suitable for educational purposes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff3b4aa68-1696-4204-931e-d52a90d9be65%2Fdf53a3fa-6e2c-4dcf-8d76-9495079de3f7%2Fn5ybz6i_processed.png&w=3840&q=75)
