to solve this question on option E. Aluminum sulfide reacts with water to form aluminum hydroxide on hydrogen sulfate were provided with the unbalanced equation as there are two aluminum atoms on three s Adam on the left hand side while only one aluminium on one cell phone at right inside. Replace a two in front off A ll. Which three and three in front off it's two s. This makes 12 hydrogen along with six Adams on the right side off to hydrogen and one Adam on the left side. Off the equation. They are balanced by placing six infront off water. This is the provided balanced equation for auction. Be the mullahs. Mask off. Aluminum hydroxide is 78 on the molar mass off aluminum sulfide is 150. The number off molds can be determined by using a formula They divided by the molecular mass giving us the moles as 0.0 945 more. The balance chemical equation is represented as follow. This I commit. Lee indicates that one mole off ailed us tree the acts to produce to moral off aluminum hydroxide. Then the number off more off a ll which three produced from 0.945 moons off a toe s can be Ditto mind by using unitary method, which is 0.189 months for the mask off aluminum hydroxide obtain in The reaction is determined by using its small on Muller. Must we know the far? The formula for number off mole is weight divided by molecular mass. Rearranging this formula, we can determine the mass off aluminum hydroxide, which turns out to be 14.7 grounds.
