Answer:
CaF2 + Li2SO4 -> CaSO4 + 2LiF
Step-by-step explanation:
When balancing equations that are not in acidic or basic solutions, you can not add extra compounds or elements to make both sides equal. In order to balance you need to change how many moles that are in the equation. Since the number of mols is equivalent to the amount of atoms that are present. Think of 3/4 being the same as 6/8 but looking at 3/4 is easier to understand.
In this chemical equation there is the same amount of Ca, S atoms, and Oxygen atoms. (You will learn later that SO4 is a polyatomic ion but that doesn’t matter in this equation). The only difference is that there is two Flourine (F) and two Lithiums (Li). This problem makes it easier because the Lithium and Flourine separate from their reactant compounds and form together as a product so you only need to focus on that compound in the products. Multiplying the entire compound by two will mean that it is the same number of Flourine atoms on both sides and the same number of Lithium atoms.
I hope this helps!
