Aluminum sulfide reacts with water to form aluminum hydroxide and hydrogen sulfide.
Write the balanced chemical equation for this reaction.
How many grams of aluminum hydroxide are obtained from 16.2g of aluminum sulfide?

Respuesta :

Answer:

See below in bold.

Explanation:

Al2S3 + 6H2O ----> 3H2S + 2AL(OH)3 is the balanced equation.

Using molar masses :

150.14 g AL2S3 gives 2 * 78.006 g Al(OH)3

So 1 g Β  .......................... Β 156,012 / 150.14 ................

16.2 g ...............................156.012 Β * 16.2 / 150.14 g

= Β 16.83 g Al(OH)3.
