Combined Gas Laws

Given: V1= 3.9L    V2= 4.13L   T1= 299K   P1=763mmHg   P2=720mmHg

Unknown: T2=?

Formula: T2=T1P2V2 / P1V1

Solution: T2= (299K)(720mmHg)(4.13L) / (763mmHg)(3.9L)
                   = 889,106.4 / 2975.7

Answer: T2=298.8K

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:

<u>1) Reactants:</u>

The reactants are:

  • <em>Molecular chlorine</em>: this is a gas diatomic molecule, i.e. Cl₂ (g)

  • <em>Molecular fluorine</em>: this is also a gas diatomic molecule: F₂ (g)

<u>2) Stoichiometric coefficients:</u>

  • <em>One volume of Cl₂ react with three volumes of F₂</em> 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) →

<u>3) Product:</u>

  • It is said that the reaction yields <em>two volumes of a gaseous product;</em> 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.
