Answer 2

Balancing the Chemical Equation

The given chemical equation is: 3H2S + 2Al = Al2S3 + 3H2. This equation represents the reaction between hydrogen sulfide and aluminum to produce aluminum sulfide and hydrogen gas.

Finding the Mass of Hydrogen Sulfide

To find the mass of hydrogen sulfide (H2S) produced, we can use the given mass of aluminum (Al), which is 10.8 grams.

Calculating the Mass of Hydrogen Sulfide

The molar ratio of aluminum to hydrogen sulfide in the balanced chemical equation is 2:3. Therefore, we can use the molar mass of aluminum to find the moles of aluminum, and then use the mole ratio to find the moles of hydrogen sulfide produced. Finally, we can convert the moles of hydrogen sulfide to grams to find the mass.

Let's calculate the mass of hydrogen sulfide using the given information.

The molar mass of aluminum (Al) is 26.98 g/mol.

The molar ratio of aluminum to hydrogen sulfide is 2:3.

Given mass of aluminum (Al) = 10.8 grams.

Calculation

1. Calculate the moles of aluminum using the given mass: Moles of Al = Given mass of Al / Molar mass of Al Moles of Al = 10.8 g / 26.98 g/mol

2. Use the mole ratio to find the moles of H2S: Moles of H2S = (Moles of Al) * (3/2)

3. Convert moles of H2S to grams: Mass of H2S = Moles of H2S * Molar mass of H2S

Let's perform the calculations to find the mass of hydrogen sulfide.
