In this case, given the undergoing chemical reaction, we can see a 4:3 mole ratio between the consumed moles of gallium and sulfur respectively, therefore, the consumed moles of sulfur, from the 100.0 g of gallium (use its atomic mass) turn out:

$n_{S}=100.0gGa*\frac{1molGa}{69.72gGa}*\frac{3molS}{4molS} \\\\n_S=1.076molS$

52. Which is true about all the different types of matter?

Svetllana [295]

Types of matter are just different ways molecules behave at certain temperatures. There's no specific atoms or molecules that make solids, liquids, or gases. Ice, water, and water vapor are all H2O, for instance. The only correct answer would be that it is made of the same basic particles, but then again, so is everything.
