Answer:
Step-by-step explanation:
Here, we want to balance the given equation
To do this, we have to ensure that the number of atoms of each element on each side of the chemical equation is the same
We can start by balancing the HF as follows:
From what we have above:
Sn = 1 on both sides
H = 2 on both sides
F = 2 on both sides
Thus, we can conclude that the reaction is balanced at this stage
We simply put the value 1 in places where we do not have another number as coefficient
