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