Introduction
Balancing chemical equations is a crucial step in understanding chemical reactions. It involves adding coefficients to the reactants or products to ensure that the number of atoms of each element is the same on both sides of the equation. In this article, we will focus on identifying the missing coefficient in the balanced equation and classifying the type of reaction.
Balancing the Equation
The given equation is:
To balance the equation, we need to add coefficients to the reactants or products. Let's start by balancing the nitrogen (N) atoms. There are 2 nitrogen atoms on the reactant side, so we need to add a coefficient of 2 in front of NH3 on the product side.
Now, let's balance the calcium (Ca) atoms. There are 3 calcium atoms on the reactant side, so we need to add a coefficient of 3 in front of Ca(OH)2 on the product side.
The equation is now balanced.
Classifying the Type of Reaction
Now that we have balanced the equation, let's classify the type of reaction. The reaction involves the exchange of partners between two compounds, resulting in the formation of two new compounds. This type of reaction is known as a double displacement reaction.
Double Displacement Reaction
A double displacement reaction is a type of chemical reaction where two compounds exchange partners to form two new compounds. The general equation for a double displacement reaction is:
In the given reaction, calcium nitride (Ca3N2) reacts with water (H2O) to form calcium hydroxide (Ca(OH)2) and ammonia (NH3). This is a classic example of a double displacement reaction.
Conclusion
In conclusion, the missing coefficient in the balanced equation is 3 and 4. The type of reaction is a double displacement reaction. Balancing chemical equations and identifying reaction types are essential skills in chemistry. By understanding these concepts, we can better comprehend the underlying mechanisms of chemical reactions and apply this knowledge to real-world problems.
