In the lab you measure 0.65 g of aluminum foil and place it in a beaker under the hood. Very carefully you measure 2.0 mL of Br2 ( 2 needs to be subscript) (density 2.928 g/mL), aslo under the hood, and pour it into the beaker with the aluminum foil. A really cool reaction occurs. What is the limiting reagent? Show ALL necessary

Attached you will find a table listing the chemicals I will be mixing in lab next week. I would like to know the reactions between the solutions. Once I have these reactions in a table, I will be able to mix unknown solutions, and identify the unknowns based on the table I will have in advance. Below is the abbreviations I ha
