Cadmium metal reacts vigorously with yellow crystals of sulfur to produce a yellow powder of cadmium sulfide. a chemist determines that 112.4 g of cadmium reacts with 32.1 g of sulfur. how much cadmium sulfide could be produced from 22.0 g of cadmium metal?

Respuesta :

The mass of cadmium sulfide produced on reacting [tex] 112.4 g [/tex] of cadmium with [tex] 32.1 g [/tex] of sulfur = [tex] 112.4 g + 32.1 g = 144.5 g [/tex]

[tex] 1 g [/tex] of cadmium forms [tex] \frac{144.5}{112.4} [/tex] cadmium sulfide.

So, [tex] 22.0 g [/tex] of cadmium will give [tex] 22.0 \times \frac{144.5}{112.4} = 28.3 g [/tex] of cadmium sulfide.
