Understanding Single Displacement Reactions
Single displacement reactions are a type of chemical reaction where one element displaces another element from a compound. These reactions involve the transfer of electrons from one element to another, resulting in the formation of new compounds. In a single displacement reaction, one element takes the place of another element in a compound, often resulting in the formation of a new compound and a new element.
The Importance of Balancing Chemical Equations
Balancing chemical equations is a crucial step in understanding and predicting the outcomes of chemical reactions. A balanced chemical equation is one where the number of atoms of each element is the same on both the reactant and product sides. This ensures that the law of conservation of mass is obeyed, and the equation is thermodynamically feasible. In the context of single displacement reactions, balancing the equation is essential to determine the products formed and the reactants consumed.
The Given Equation
The given equation is:
In this equation, we have sodium bromide (NaBr) reacting with chlorine gas (Cl2) to form two products. The task is to identify the chemical symbols that will complete the equation.
Identifying the Products
To identify the products, we need to consider the possible reactions between sodium bromide and chlorine gas. Sodium bromide is a salt of sodium and bromine, while chlorine gas is a halogen. When sodium bromide reacts with chlorine gas, the bromine atoms in the sodium bromide are displaced by chlorine atoms, resulting in the formation of sodium chloride (NaCl) and bromine gas (Br2).
Balancing the Equation
To balance the equation, we need to ensure that the number of atoms of each element is the same on both the reactant and product sides. The balanced equation is:
In this balanced equation, the number of sodium (Na) atoms, chlorine (Cl) atoms, and bromine (Br) atoms is the same on both the reactant and product sides.
Conclusion
In conclusion, the chemical symbols that will complete the equation for the single displacement reaction are NaCl and Br2. These products are formed when sodium bromide reacts with chlorine gas, resulting in the displacement of bromine atoms by chlorine atoms. The balanced equation is a crucial tool in understanding and predicting the outcomes of chemical reactions, and it is essential to ensure that the number of atoms of each element is the same on both the reactant and product sides.
