How do three states of matter arise?

Evgen [1.6K]

The status of the state of matter of a material defines the phase. Pellet currently case 16 is defined; three of which solid, liquid and gas are referred to as conventional cases. There are a total of 16 state currently defined, these classic except; liquid crystal, amorphous solid, magnetic regularly, superconducting, superfluid, the Bose-Einstein condensation, Rydberg molecules, plasma (ionized gas), the quark-gluon plasma, degenerate matter, Superkate, the stringy liquid and SuperCam mine. Daily life in general, solid materials, include liquid or gaseous, but outside world, 99% of the material in the universe plasma (ionized gas) is in the form.

a compound is found to contain 31.1% sulfur and 68.9% chlorine determine the empirical formula for the sulfur and chlorine sampl

ollegr [7]

Answer:

Empirical formula = S₁Cl₂ = SCl₂

Explanation:

The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.

This compound contains 31.1% sulfur and 68.9% chlorine.

That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.

Convert the mass of each element to moles using the molar mass from the periodic table.

Moles of Sulfur = $\frac{31.1}{32.065 } \\$

= 0.9699

Moles of Chlorine= $\frac{68.9}{35.453 } \\$

= 1.9434

Divide each mole value by the smallest number of moles calculated.

Units of sulfur = $\frac{0.9699}{0.9699} \\$

= 1

Units of Chlorine = $\frac{1.9434}{0.9699} \\$

= 2

Empirical formula = S₁Cl₂ = SCl₂
