Be sure to specify states such as (aq) or (s). If a box is not needed leave it blank. If no reaction occurs leave all boxes blank and click on "submit". Consider the reaction when aqueous solutions of barium chloride and sodium carbonate are combined. The net ionic equation for this reaction is: + + + +
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.

**Consider the Reaction Between Barium Chloride and Sodium Carbonate:**
When aqueous solutions of **barium chloride** and **sodium carbonate** are combined, the net ionic equation for this reaction is required.
**Equation Representation:**
- There are six boxes in total within the equation layout, arranged in the following manner:
```
[ ] + [ ] + [ ] → [ ] + [ ]
```
---
**Explanation of the Diagram:**
1. **Left side of the equation**:
- Three boxes are labeled with plus signs between them. These represent the reactants which are the ions present in the aqueous solutions before the reaction occurs.
2. **Arrow (→) in the middle**:
- Indicates the direction of the chemical reaction, showing how the reactants are converted into products.
3. **Right side of the equation**:
- Two boxes separated by a plus sign. These boxes represent the products formed by the chemical reaction.
Please fill in the appropriate reactants and products, indicating their states (aq or s) to complete the net ionic equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4126b89b-6ee3-437f-8fcf-aa0e90855818%2Fc7257710-d1ca-4073-bc6a-c07646f1f85a%2Fdf44q2g_processed.jpeg&w=3840&q=75)
