1a. In a reaction between the elements aluminum and chlorine, aluminum chloride is produced. Write the balanced chemical equation.



1b.If 2.00 moles of Al react with Cl2 according to the above equation, how many grams of AlCl3 will form?

Answer 1

Step-by-step explanation:

Part A

2 Al + 3 Cl_2 ==> 2 AlC_3

Part B

The balanced equation tells you for every 2 mols of Al you will produce 2 mols of AlCl_3

Find the mass of 1 mol of AlCl_3

Mass Al = 27

Mass 3Cl = 3*35.5 = 106.5 Add

Mass 1 mol AlCl_3 = 133.5

Answer: 2 mols of AlCl_2 = 267.0 grams
