In the simulation, were you able to use noninteger numbers $($like $(1)/(2)$ or $0\mathrm{.}43)$ for the coefficients in a balanced equation? Why do you think this is$?$

a$)$ Which of the following are coefficients you could use in a balanced equation?

$(1)/(2)1269$

b$)$ If you were balancing an equation containing the O$2$ molecule, which of the following wouldbe correct representations of O$2$ and its coefficient?

$(1)/(2)$O$2$ O$23$O$26$O$23$O $5$O$3$

c$.$ What do you have to do to the coefficients of equation I below to get to equation II$?$

i$.2$ SnO$2+4$ H$22$ Sn $+4$ H$2$O

ii$.$ SnO$2+2$ H$2$ Sn $+2$ H$2$O

d$.$Both equation I and II are balanced, but equation I is the correct way to write the balanced

equation.

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

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