Answer:

  • We want to take inventory of the right and left side
  • Right: S=1 O = 2 Li = 2 Se= 1
  • Left: S= 1 Se=2 Li= 2 O=1
  • Lets balance out each side because we see we are off by 1 oxygen on the left
  • Add a coefficient of 2 on the Li2O
  • Add a coefficient of 2 on the right Li2Se
  • Now we have So2+ 2Li2Se ---> SSe2+ 2Li2O
