Re: M. 15

You will first write the chemical equation that is given and balance it. Al(s) + Cl2(g) ---> AlCl3(s) After you balance the chemical equation, you find the moles of Al and Cl2 to help you determine the limiting reactant. To find the moles, you would convert to moles. So for Al, you would use 255g an...
