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.
given the following equation what is the net ionic equation?

**Chemical Reaction: Precipitation of Barium Sulfate**
When sodium sulfate reacts with barium hydroxide, a precipitation reaction occurs, forming barium sulfate as a solid. Below are possible representations of the reaction:
1. **Reaction Equation:**
\[
\text{Na}_2\text{SO}_4(aq) + \text{Ba(OH)}_2(aq) \rightarrow \text{BaSO}_4(s) + 2\text{NaOH}(aq)
\]
2. **Options:**
- \(\boxed{\phantom{X}}\) \(\text{Na}_2\text{SO}_4(aq) + \text{Ba(OH)}_2(aq) \rightarrow \text{BaSO}_4(s)\)
- \(\boxed{\phantom{X}}\) No reaction
- \(\boxed{\phantom{X}}\) \(2\text{Na}^+(aq) + \text{SO}_4^{2-}(aq) + \text{Ba}^{2+}(aq) + 2\text{OH}^-(aq) \rightarrow \text{BaSO}_4(s) + 2\text{Na}^+(aq) + 2\text{OH}^-(aq)\)
- \(\boxed{\phantom{X}}\) \(\text{SO}_4^{2-}(aq) + \text{Ba}^{2+}(aq) \rightarrow \text{BaSO}_4(s)\)
- \(\boxed{\phantom{X}}\) \(2\text{Na}^+(aq) + 2\text{OH}^-(aq) \rightarrow 2\text{Na}^+(aq) + 2\text{OH}^-(aq)\)
**Explanation:**
- **(aq)** indicates an aqueous solution.
- **(s)** indicates a solid precipitate.
- This reaction involves ions in a solution combining to form a solid compound, highlighting the process of ionic exchange and solid formation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1385b10f-f9b1-451c-97aa-8152fc0259bb%2Fb7992bd2-9362-46fe-a018-acae882314ed%2F93n3ehn_processed.jpeg&w=3840&q=75)
