What mass of aluminum hydroxide will be produced when 0.460 grams of aluminum sulfide react with water? How many grams of hydrogen sulfide are produced, according to the following equaton?

Question

Al2S3 + H20 -------> Al(OH)3 + H2S

Steve · Answer

First, balance the equation:

Al₂S₃ + 6H₂O --> 2Al(OH)₃ + 3H₂S

Al₂S₃ = 150g/mol
H₂S = 34g/mol

.46g of Al₂S₃ is 0.003 mole

each mole of Al₂S₃ produces 3 moles of H₂S, so you'd get

.009moles of H₂S = 0.313g
