Molecular chlorine and molecular fluorine combine to form a gaseous product. Under the same conditions of temperature and pressu

uranmaximum [27]

Answer:

Cl F₃

Explanation:

1) Reactants:

The reactants are:

Molecular chlorine: this is a gas diatomic molecule, i.e. Cl₂ (g)

Molecular fluorine: this is also a gas diatomic molecule: F₂ (g)

2) Stoichiometric coefficients:

One volume of Cl₂ react with three volumes of F₂ means that the reaction is represented with coefficients 1 for Cl₂ and 3 for F₂. So, the reactant side of the chemical equation is:

Cl₂ (g) + 3F₂ (g) →

3) Product:

It is said that the reaction yields two volumes of a gaseous product; then, a mass balance indicates that the two volumes must contain 2 parts of Cl and 6 parts of F. So, one volume must contain 1 part of Cl and 3 parts of F. That is easy to see in the complete chemical equation:

Cl₂ (g) + 3F₂ (g) → 2Cl F₃ (g)

As you see, that last equation si balanced: 2 atoms of Cl and 6 atoms of F on each side, and you conclude that the formula of the product is ClF₃.

which of the following methods is most appropriate to use to determine the number of different-colored components in a sample of

Andru [333]

The answer is paper chromatography using different solvents with a range of polarities as the mobile phase.

Paper chromatography- Low-molecular-mass molecules can be separated using paper chromatography based on how evenly they are distributed in the stationary and mobile phases. Paper chromatography is regarded as a potent analytical technique because of its low cost and the availability of numerous procedures for the separation of chemicals.

A small amount of a sample solution is poured onto a strip of chromatography paper in a paper chromatography experiment. After that, a solvent is used to suspend the chromatography paper. The sample solution's constituent components split out into bands of distinct hue as the solvent goes up the paper.

The speed of the chromatography process is influenced by the solvent's polarity. Therefore, we may conclude that all of the other components in the mixture move more quickly during the chromatography experiment if the solvent's polarity is increased.

Thus, answer is paper chromatography using different solvents with a range of polarities as the mobile phase.
