Question

an unbalanced chemical equation for the reaction of boron fluoride with lithium sulfite is shown. bf₃ + li₂so₃ → b₂(so₃)₃+lif what is the coefficient of lithium fluoride in the balanced chemical reaction? 1 3 4 6

Explanation:

Step1: Balance el átomo de Boro

$$2BF_{3}+Li_{2}SO_{3}\to B_{2}(SO_{3})_{3}+LiF$$

Step2: Balance el grupo $SO_{3}$

$$2BF_{3}+3Li_{2}SO_{3}\to B_{2}(SO_{3})_{3}+LiF$$

Step3: Balance el átomo de Litio y Flúor

$$2BF_{3}+3Li_{2}SO_{3}\to B_{2}(SO_{3})_{3}+6LiF$$

Answer:

6
