Capitolo 7, Problema 69a
Write a balanced equation for the reaction that occurs in each of the following cases: (a) Potassium metal is exposed to an atmosphere of chlorine gas.
Guida verificata passo dopo passo1
Identify the reactants involved in the reaction. In this case, the reactants are potassium metal (K) and chlorine gas (Cl2).
Write the unbalanced chemical equation by placing the reactants on the left side and the products on the right side. Since potassium reacts with chlorine, the product is potassium chloride (KCl). The unbalanced equation is: K + Cl2 → KCl.
Balance the equation by adjusting the coefficients to ensure that the number of atoms for each element is the same on both sides of the equation. Start by balancing the chlorine atoms.
After balancing the chlorine, adjust the coefficients for potassium so that the number of potassium atoms is equal on both sides of the equation.
Verify that the equation is balanced by counting the atoms of each element on both sides of the equation to ensure they are equal.

Balancing Chemical Equations
Balancing chemical equations involves ensuring that the number of atoms of each element is the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. To balance an equation, coefficients are adjusted in front of the chemical formulas to achieve equal atom counts.

Balancing Chemical Equations
Reactivity of Alkali Metals
Alkali metals, such as potassium, are highly reactive, especially with halogens like chlorine. When potassium reacts with chlorine gas, it forms potassium chloride. This reaction is characterized by the transfer of electrons from the alkali metal to the halogen, resulting in the formation of ionic bonds and the release of energy in the form of heat and light.

Ionic Compounds Formation
Ionic compounds are formed when metals react with nonmetals, resulting in the transfer of electrons. In the case of potassium and chlorine, potassium donates one electron to chlorine, leading to the formation of K+ and Cl- ions. These oppositely charged ions attract each other, creating a stable ionic compound, potassium chloride (KCl), which can be represented in a balanced chemical equation.
