2Al+3Cl2---> 2AlCl3 (i cant remember if this is balanced equation or not if not can you do that too? thank you i appreciate it.)
If I have 5.0 g Aluminum how much AlCl can I produce?
Step 1 convert grams Al to moles Al: (the dashes resemble a fraction)
5.0 g Al
- times - =
Step 2: convert mol al to mol AlCl3
0.19 mol Al
- times - =
1
step 3: convert MOL AlCl3 to GRAMS AlCl3
0.19 mol AlCl3
- times - = 25.4 g AlCl3

THIS FIRST # PART PROBLEM IS STOICHEMITRY for chemistry if you know please help me out I have been struggling on this for a week now..thank you so much.
This next part is LIMITING REACTANTS:
If Al produces 25.4 g of AlCl3 and Cl2 gas produces 20.0 g AlCl3 what is my limiting reactant, Al or C2??
How do i determine my percent yeild if my actual yeild is 19.5g???
i put a link to the picture!!

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
