Answer:
The given chemical equation is:
CaF2 + Li2SO4 -> CaSO4 + LiF
To balance this equation, we need to ensure that there is an equal number of each type of atom on both sides of the equation.
Let's go step by step to balance the equation:
1. Start with the calcium (Ca) atoms. There is one Ca atom on the left side and one Ca atom on the right side. They are already balanced.
2. Move on to the fluorine (F) atoms. There are two F atoms on the left side, but only one F atom on the right side. To balance them, we need to put a coefficient of 2 in front of LiF on the right side:
CaF2 + Li2SO4 -> CaSO4 + 2LiF
3. Next, balance the sulfur (S) atoms. There is one S atom on the left side and one S atom on the right side. They are already balanced.
4. Finally, balance the lithium (Li) atoms. There are two Li atoms on the left side, but only one Li atom on the right side. To balance them, we need to put a coefficient of 2 in front of Li2SO4 on the left side:
CaF2 + 2Li2SO4 -> CaSO4 + 2LiF
Now the equation is balanced, with an equal number of each type of atom on both sides.
Therefore, the balanced chemical equation is:
CaF2 + 2Li2SO4 -> CaSO4 + 2LiF
