I really need help please !? asap

lol you have a pretty high expectation of people on the internet
do you really expect someone to do your entire chemistry assignment for you for 3 points on yahoo answers...
you obviously haven't attempted them either and you've asked people to help you do your entire assignment before... you need to actually try them yourself because you'll end up having to ask someone on here all the time and not learn a single thing..

anyways here's some pretty subtle hints to finish the questions
1)
Fe + O2 → Fe2O3

times Fe2O3 by 2 and then just balance out the rest of the equation.

once you do that, divide the entire equation so it's just 1 mole of Fe and then times that by the amount of Fe they've given you and find out how much O2 you need to react with that many moles of Fe.

2) balance the equation yourself. it's not that hard.
find out the mass of 1 mole of CaCl2 equals (find molecular weight of Ca and add that to twice that of the molecular weight of Cl) use your periodic table or wiki
since you have the mass, use 1 mole of CaCl2 = molar mass to calculate the number of moles you have

since it's excess sodium whatever, you assume that the reaction goes to completion so just use your balanced equation.

3) same steps, balance it yourself and use that equation. easy enough.

4) it's 4 moles because 8 moles of Li is just 4x that whole equation

5)find molar mass of 1 mole of KClO3, use that to find the moles you have. then use the already balanced equation to find the moles of O2 you get
then you just times that by the molar mass of oxygen.

6) 2Al + 6HCl -> 2AlCl3 + 3H2
times that by 3 because you have 6 moles of Al (2x3=6)
see that you need how many moles of HCl to react with Al
i'll just do this one because it's hard to explain without doing it
