Hydrogen sulfide gas can be produced from the reaction of aluminum sulfide and water according to the following equation: Al2S3(s) 6H2O(l) > 3 H2S(g) 2Al(OH)3(aq) What volume of hydrogen sulfide gas is produced if 65.0 g Al2S3 reacts at 90.0 oC and 0.987 atm,

The volume of hydrogen sulfide gas is 38.8 L.

Explanation:

The given reaction equation is as follows.

Mass of is given as 65.0 g. Hence, moles of (molar mass = 150.158 g/mol) is calculated as follows.

As 1 moles of is giving 3 moles of . Hence, moles of formed by 0.433 moles of are as follows.

Here, pressure is 0.987 atm and temperature is . Therefore, volume of hydrogen sulfide is calculated as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

Thus, we can conclude that volume of hydrogen sulfide gas is 38.8 L.  

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
