The most important state in determining the state of a substance is
temperature. This is because the kinetic energy of a substance's
molecules depend on its temperature. For example, an increase in
temperature speeds up the movement of molecules. A decrease in
temperature slows down the movement of molecules.
This is
important because by increasing or decreasing a substance's temperature,
you are also adding or removing energy from it. And when a substantial
amount of energy has been added or removed, a substance can change its
state from solid > liquid > gas or the other way around.
Answer:
balanced chemical equation is
2 SiO₂ + 3 C₂ = 2 SiC + 4 CO
1 mole tungsten ------------- 6.02 x 10²³ atoms
0.0845 moles ---------------- ( atoms tungsten )
atoms tungsten = 0.0845 x ( 6.02 x 10²³) / 1
atoms tungsten = 5.08 x 10²² / 1
= 5.08 x 10²² atoms of tungsten
