Calculate the mass in grams of iodine (i2) that will react completely with 20.4 g of aluminum (al) to form aluminum iodide (ali3)

The balanced chemical reaction between Aluminum and Iodine is,

Mass of Aluminum = 20.4 g

Moles of Aluminum =

The stoichiometric mole ratio of iodine to Al:

Moles of Iodine that would react with 0.756 mol Al=

Mass of iodine =

Therefore, 287.8 g iodine would react with 20.4 g aluminum completely to form aluminum iodide.

what are the two models

explanation:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
