Question
How many grams of aluminum hydroxide is obtained from 13.7 g of aluminum sulfide?
Express your answer in grams to three significant figures.
Solid aluminum sulfide reacts with water to form solid aluminum hydroxide and gaseous hydrogen sulfide.

Transcribed Image Text:Solid aluminum sulfide reacts with water to form solid
aluminum hydroxide and gaseous hydrogen sulfide.
Al½S3(s) + H2O(1) → Al(OH)3 (s) +H2S(g)
Then count each kind of atom on the two sides of the equation. There are two Al atoms, three S atoms, two H
one O atom on the left side and one Al atom, three O atoms, five H atoms, and one S atom on the right side.
the number of Al atoms, place a coefficient of 2 in front of Al(OH)3:
Al, S3(s) + H2O(1) → 2Al(OH)3 (s) +H»S(g)
Now there are two Al atoms, three S atoms, two H atoms, and one O atom on the left side and two Al atoms,
eight H atoms, and one S atom on the right side. To balance the number of S atoms, place a coefficient of 3 in f
Al, S3(s) + H2O(1)
2Al(OH)3 (s) + 3H,S(g)
Now there are 2 Al atoms, 3 S atoms, 2 H atoms, and 10 atom on the left side and 2 Al atoms, 6 O atoms,
and 3 S atoms on the right side. To bring the H and O atoms into balance, place a coefficient of 6 in front of H2
Al,S3(s) + 6H2O(1) → 2Al(OH)3(s)+ 3H2S(g)
Now there are 2 Al atoms, 3 S atoms, 6 O atoms, and 12 H atoms on each side. The equation is balanced.
