10. What do you have to do to the coefficients of equation I below to get to equation II?
i. 2 SnO2 + 4 H2 2 Sn + 4 H2O
ii. SnO2 + 2 H2 Sn + 2 H2O
a) Both equation I and II are balanced, but equation I is the correct way to write the balanced equation.
b) Can you divide equation II by another factor and still have it be correct? Why or why not?
c) In a complete sentence, write down a method you could use to determine if an equation is written in the correct way.
