Explanation / Answer

So in order to balance an equation, the best method is to listlist elements below each so of the reaction.   Under eachside you should have Al, O, C, Cl.
First lets balance Al, Since 2 is on the first side, there needs tobe a 2 coefficient on the second side in front of AlCl3 andaluminums are now balanced. Next, the left side now was 6 Cl's so add coefficient 3 to Cl2on the first side and now chlorines are balanced. On the right side we have three oxygens so put a 3 in front ofCO and now oxygens are balanced. Lastly, we now have 3 Carbons on the right side, so add athree coefficient to the carbon on the left. Now everythingis balanced an Al2O3 will have coefficient 1. For the stiochiometry problem, all you need to do is set upthe appropriate conversion factors to convert from grams of acompound to atoms of an element in the compound. Keep in mindthat in one mole of this compound there is 2 moles N, 4 Moles H,and 3 moles O, which is derived from the emperical formula. The conversion factors are below. Good luck! 10g NH4NO3 1 Mol NH4NO3 2 Mol N 6.02 times 1023 atoms of N 80.052 g NH4NO3 1 Mol NH4NO3 1 Mol N 10g NH4NO3 1 Mol NH4NO3 2 Mol N 6.02 times 1023 atoms of N 80.052 g NH4NO3 1 Mol NH4NO3 1 Mol N
