The Attempt at a Solution
I just don't know where to start with this...
i don't get what the two half reactions would be like the fe loses an electron and the iodine gains an electron.
so i got the two half reactions a
FeI2 ==> FeCl3
HIO3 ===> ICl
i don't get how to balance these because in the first one where does the iodine...
Homework Statement
For those who have mastered the balancing of any type o redox equation, an extra challenge is provided below. Balance each of the following equations. Note: all of the reactions take place in aqueous solution.
Homework Equations
HIO3 + FeI2 + HCl ====> FeCl3 + ICl +...
same here. warm air rises becasue its less dense. the lamp warms the surrounding air, then that air rises while cool air which is more denses comes down.
ps what's up. guess who i am
thank you, i was trying to think of a different way. but this was the only way i could think of and i wanted to make sure this was right because there is a follow up question to this. again thanks
