Why is beta stopped by aluminum?
Beta particles are essentially electronsAluminum foil is of sufficient density that it will scatter or absorb the betaThere is nothing special about aluminumAny material with a similar density will do the trick.
Al2S3 + 6H2O- 2Al(OH)3 + 3H2S 139g(1 mol H2S/150.14g)(3 mol H2s/1 mol H2S)2.78 mol H2S 2.78mol H2S(34.08 g H2S/1 mol H2S)94.7 g H2S Not sure about thisOh I actually did it right.
