Chemical reactions are a fundamental concept in chemistry, and understanding how to balance equations is crucial for solving problems and predicting outcomes. In this article, we will explore the reaction between calcium and zinc carbonate to form calcium carbonate and zinc, and determine the correct balanced equation.

Understanding the Reaction

The reaction between calcium and zinc carbonate can be represented by the following equation:

$$Ca + ZnCO_3 \rightarrow CaCO_3 + Zn$$

This equation shows that calcium (Ca) reacts with zinc carbonate (ZnCO3) to form calcium carbonate (CaCO3) and zinc (Zn). However, we need to determine if this is the correct balanced equation.

Balancing Equations

To balance an equation, we need to ensure that the number of atoms of each element is the same on both the reactant and product sides. In this case, we need to balance the equation to reflect the correct reaction.

Option A: $Ca - ZnCO_3 + CaCO_3 - Zn$

This option is incorrect because it shows calcium (Ca) being subtracted from zinc carbonate (ZnCO3), which is not a valid reaction. Additionally, the equation is not balanced, as the number of atoms of each element is not the same on both sides.

Option B: $Ca + ZnCO_3 - CaCO_3 + Zn$

This option is also incorrect because it shows calcium (Ca) being added to zinc carbonate (ZnCO3), but then subtracting calcium carbonate (CaCO3) and zinc (Zn). This is not a valid reaction, and the equation is not balanced.

Option C: $Ca + ZnCO_3 \rightarrow CaCO_3 + Zn$

This option is the correct balanced equation, as it shows calcium (Ca) reacting with zinc carbonate (ZnCO3) to form calcium carbonate (CaCO3) and zinc (Zn). The equation is balanced, as the number of atoms of each element is the same on both sides.

Conclusion

In conclusion, the correct balanced equation for the reaction between calcium and zinc carbonate to form calcium carbonate and zinc is:

$$Ca + ZnCO_3 \rightarrow CaCO_3 + Zn$$

This equation shows that calcium (Ca) reacts with zinc carbonate (ZnCO3) to form calcium carbonate (CaCO3) and zinc (Zn), and is the correct representation of the reaction.
