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.
What is the net ionic equation?
![The image contains a chemical equation written in a notebook. The equation is:
\[ \text{2Na}_3\text{PO}_4(\text{aq}) + 3\text{Ca}(\text{NO}_3)_2(\text{aq}) \rightarrow \text{Ca}_3(\text{PO}_4)_2(\text{s}) + 6\text{NaNO}_3(\text{aq}) \]
This equation represents a chemical reaction where sodium phosphate reacts with calcium nitrate to produce calcium phosphate as a solid precipitate and sodium nitrate in an aqueous solution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa7d7525f-9c27-4dea-8079-91e82ba48598%2Fc0d92f50-7f3f-4ee4-a362-8621f9d46517%2Fi22mo5e_processed.jpeg&w=3840&q=75)
Balanced molecular equation:
Balance molecular equation can be define as the reaction in which number of atoms of all the elements on the reactant side are equal to the number of atoms of all the elements on the product side.
Net ionic equation: In net ionic equation we represent only those compounds or ions which involved in a chemical reaction directly.
Note: Spectator ions can be define as the ions which are present on both product and reactant side of the complete ionic equation.
