I dont think I can use Grignard can I? PLEASE HELP. CH3CH2Br + CH3CH2Mg/EtoEt -> CH3Ch2Ch2Ch2MgBr + NaN3/EtOH -> CH3Ch2Ch2Ch2N=N=N + LiAlH4/H20 CH3Ch2Ch2Ch2NH2? Then what? does this even work?

If 300.0g of NaN3 (Sodium Azide) is combined with 300.0g Pb(CH3O2)2 (Lead acetate) which compound runs out first?

According to my book, I think it only mentions about NaN3, KNO3 and SiO2 as starting materials. Among the three, which one is least important? Would it be necessary to have it present in a precise stoichiometric ratio? Why or why not? Thanks for your help.

How many grams in 4.00 moles of Fe2O3? Answer 4 Moles Mass = 159.7 grams 4 X 159.7/1 = 6.388 or 6.39 grams. How do you get 6.39X102grams? Fe is +2 and O is 2. you have 2-Fe and 3-O why would this not be 6.39X10-2 grams

1. Use: mass = (volume)*(density), or grams = (milliliters)(grams/ml) to calculate the mass (grams) of each compound. 2. Find the molar mass of toluene. 3. Divide the mass (grams) of toluene by the molar mass of toluene to convert grams to moles. 4. Convert the grams of ...

Answer is 1.104L Oh remember that there are 0.028 mol in 1.88g of NaN2. Final, in 0.028mol of NaN3, there is 0.042 mol of N2. This is your n. so, V= ( nRT)/P remember, you are given R, T and P Hope this helps:)
