The reaction between Mg and Br2 results in the formation of MgBr2. The balanced chemical equation is:
Mg + Br2 → MgBr2
The reaction represented is a single displacement reaction, where potassium (K) displaces iodine (I2) from potassium iodide (KI) to form potassium iodide and elemental iodine.
In the reaction ( \text{I}_2(s) \rightarrow \text{I}_2(g) ), entropy increases. This is because the transition from solid iodine to gaseous iodine involves a change from a more ordered state (solid) to a more disordered state (gas), where the molecules have greater freedom of movement and occupy a larger volume. As a result, the overall entropy of the system increases during this phase change.
In the reaction ( \text{I}_2(s) \rightarrow \text{I}_2(g) ), the entropy increases. This is because the transition from solid iodine to gaseous iodine involves a change from a more ordered state (solid) to a more disordered state (gas), where the molecules have greater freedom of movement. As a result, the number of possible microstates increases, leading to higher entropy in the gaseous phase compared to the solid phase.
The L2-L3 vertebrae are located in the lower back, specifically in the lumbar region. They are the second and third vertebrae from the top of the lumbar spine, just below the L1-L2 vertebrae and above the L3-L4 vertebrae.

The balanced equation is: Br2 + 2Kl -> 2KBr + I2. This means there is a 2 in front of the underlined substance, KI.
The reaction between magnesium and iodine is a synthesis reaction, resulting in the formation of magnesium iodide. The balanced chemical equation for this reaction is: Mg + I2 → MgI2. In this reaction, magnesium atoms react with iodine molecules to produce magnesium iodide, a compound consisting of magnesium cations and iodide anions held together by ionic bonds. This reaction is a classic example of a metal reacting with a non-metal to form an ionic compound.
The entropy increases in this reaction, as the solid reactant (I2(s)) is becoming a gas (I2(g)), which represents a higher degree of disorder and randomness on a molecular level. The increased entropy contributes to the spontaneity of the reaction.
The entropy increases, as going from a solid to a gas increases disorder or randomness in the system. This is because gases have more freedom of movement and energy compared to solids.
To balance the reaction Cl2 + 2Kl -> 2KCl + L2, you need to adjust the coefficients for each compound so that the number of each type of atom is the same on both sides of the reaction arrow. By changing the coefficient of KI to 2, the number of K and I atoms are balanced, and the reaction is balanced as a result.

The given reaction represents a double displacement reaction also known as a metathesis reaction. In this type of reaction, the cations and anions of two different compounds switch places to form two new compounds.
The reaction represented is a single displacement reaction, where potassium (K) displaces iodine (I2) from potassium iodide (KI) to form potassium iodide and elemental iodine.
The reaction is already balanced as it is written: Cl₂ + 2Kl → 2KCl + Cl₂. Each side of the reaction has the same number of atoms for each element.
