--What do you have to do to the coefficients of equation I below to get to equation II? i) 2 $SnO_{2}$ + 4 $H_{2}$ --> 2 Sn + 4 $H_{2} O$
ii) $SnO_{2}$ + 2 $H_{2}$ --> Sn + 2 $H_{2} O$

--Can you divide equation II by another factor and still have it be correct? Why or why not?

--In a complete sentence, write down a method you could use to determine if an equation is written in the correct way.
