Which type of reaction is represented by this equation?
(1) synthesis
(2) decomposition
(3) single replacement
(4) double replacement
Answer: Option (2) is the correct answer.
Explanation:
An equation in which the the number of reactants equal the number of products is known as a balanced equation.
Whereas a reaction in which a compound dissociates into two or more compounds is known as a decomposition reaction.
Therefore, the given reaction represents that decomposes into KCl and .
Hence, it is a decomposition reaction.
Decomposition reaction is the type of reaction that is represented by the given equation. Therefore, the correct option is option 2.
A chemical reaction called a decomposition reaction, often referred to as an analysis or dissociation, occurs when a compound disintegrates into more basic elements. A single compound is transformed into two or more products in this reaction, which may be elements or other compounds.
Decomposition reactions are typically induced by heat, light, electricity, or the presence of a catalyst. These reactions occur because the reactant compound is unstable under certain conditions, leading to its breakdown into more stable products. Therefore, is a decomposition reaction.
Therefore, the correct option is option 2.

A solution can exist in three phases: solid, liquid and gas, depending on the temperature and pressure. The pH of the solution can also change based on the nature of ions present in it. Understanding the nature and properties of solutions is crucial for many chemical reaction processes.
A solution can exist in three phases depending on the temperature and pressure, which are: gas, liquid, and solid. These are depicted in a phase diagram (an illustrative depiction that shows the states of a substance under different conditions of temperature and pressure).Consider the phase diagrams for a pure solvent and a solution. When a nonvolatile solute is dissolved in a solvent, a solution is formed. These states coexist and are in a state of thermal equilibrium at specific combinations of pressures and temperatures.
In addition to the physical phase, the pH of the solution can also be considered as a 'phase.' The pH can decrease, increase, or even show a pattern of increase and then decrease depending on the nature of ions present in the solution.
Solutions are crucial to life-sustaining processes as well as other chemical reaction processes. It's important to know the nature of solutions and factors determining its formation and properties for understanding various biological, geological and industrial processes.

Electronic configuration is the distribution of electrons of an atom in atomic orbitals. As we know Oxygen is a non metal and is present in group 6 and period 2 with atomic number 8. The atomic number in fact specifies the number of protons. Hence, for a neutral oxygen atom there must be 8 electrons to balance the charges of protons.
These 8 electrons are distributed in two main energy levels i.e. n = 1 and 2 and sub energy levels i.e. s and p. According to certain rules like Aufbau Principle, Pauli's Exclusion Principle and Hund's Rule the electronic configuration for eight electrons is as,
1s², 2s², 2px², 2p¹, 2p¹
The electronic configuration for oxygen is 1s2 2s2 2p4.
The electron configuration for oxygen is 1s2 2s2 2p4.
In the electron configuration, the numbers represent the energy levels (1s, 2s, 2p), and the superscripts represent the number of electrons in each orbital. The electron configuration follows the Aufbau principle, which states that electrons fill the lowest energy levels first.
In the case of oxygen, there are 8 electrons in total. The first two electrons fill the 1s orbital, the next two fill the 2s orbital, and the remaining four fill the 2p orbital (with two electrons each in the three 2p orbitals).
