For the following reaction, calculate how many moles of FeCl3 are produced if [x] grams of Cl2 are reacted with sufficient Fe. 2 Fe(s) + 3 Cl2(g) –> 2 FeCl3(s)

Choose the best answers to fill in the blanks in the following passage.  Some answers may be used more than once, or not used at all. Chemical reactions may be classified into reaction ‘types.’  There are many such possible systems, but one way is to organize reactions according to whether materials are coming together, breaking down, or changing bonding partners.  In a 1)______________________ reaction, two or more materials combine to produce a single product.  In a 2)_____________________ reaction, one material is broken down into two or more products.  In a 3)___________________ reaction, one element is replaced for another in a compound.  Finally, in a 4)____________________reaction, two materials ‘swap’ bonding partners, to generate two new products.
