Question

Balance the chemical equations:

MgF₂+Li₂CO₃→MgCO₃+LiF
A. 1:2:2:1
B. 2:1:2:1
C. 1:1:2:1
D. 2:2:1:1

Answer 1

The balanced chemical equation MgF₂ + Li₂CO₃ → MgCO₃ + LiF corresponds to option A: 1:2:1:2.

Step-by-step explanation:

To balance the equation MgF₂ + Li₂CO₃ → MgCO₃ + LiF, we need to ensure that the number of atoms of each element is the same on both sides of the reaction. After carefully examining the equation, we can determine that the correct coefficients to balance this equation are 1, 2, 1, and 2, respectively. So, the balanced equation is MgF₂ + 2Li₂CO₃ → MgCO₃ + 2LiF. This corresponds to option A: 1:2:1:2.

The given chemical equation is:

MgF₂ + Li₂CO₃ → MgCO₃ + LiF

This equation is balanced with a ratio of 1:2:2:1. Each element and compound on both sides of the equation has an equal number of atoms. Therefore, the correct answer is A. 1:2:2:1.
