How would you balance the following equation? #?BF_3 + ?Li_2SO_3 -> ?B_2(SO_3)_3 + ?LiF#
Start with a species that you can see is not present in equal quantity on each side of the equation.
Perhaps you could recognize that Boron is not present in equal quantity on both sides of the equation - fix it by making the quantity equal eachother.
Notice that by doing this, we changed the number
Let's make the quantity of
You'll notice now that that we have changed the quantity of species
You'll notice now that all the species have equal quantities across the chemical system and that Boron Sulfite does not need a coefficient.
The balanced reaction is:
