Answer:

The answer to your question is         CdCl₂  ⇒   Cd⁺²  +  2Cl⁻¹      

Explanation:

Data

Reactant = CdCl₂ (aq)

Process

1.- Determine the products of this reaction

The products will be the elements that form part of this compound (Cadmium and chlorine).

2.- Write the dissociation reaction

                      CdCl₂  ⇒   Cd⁺²  +  Cl⁻¹

3.- Balance the reaction

                      CdCl₂  ⇒   Cd⁺²  +  Cl⁻¹      

            Reactants    Elements     Products

                    1                 Cd                 1

                    2                 Cl                  1

The reaction is unbalanced

                     CdCl₂  ⇒   Cd⁺²  +  2Cl⁻¹      

            Reactants    Elements     Products

                    1                 Cd                 1

                    2                 Cl                  2

A sample of a compound of xenon and fluorine contains molecules of a single type; XeFn, where n is a whole number. If 5.0 x 1020
kicyunya [14]

Answer:

4

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by N_0.

Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.

Avogadro constant:-

N_a=6.023\times 10^{23}

Hence,

Mass of XeF_n = 131.293+ n18.998 g

So,

6.023\times 10^{23}  molecules have a mass of 131.293+ n18.998 g

Also,

1  molecules have a mass of \frac{(131.293+ n18.998)}{6.023\times 10^{23}} g

So,

5.0\times 10^{20}  molecules have a mass of \frac{(131.293+ n18.998)}{6.023\times 10^{23}}\times 5.0\times 10^{20} g

Also, given mass = 0.172 g

Thus,

\frac{(131.293+ n18.998)}{6.023\times 10^{23}}\times 5.0\times 10^{20}=0.172

\frac{18.998n+131.293}{1204.6}=0.172

18.998n+131.293=207.1912

n=\frac{75.8982}{18.998}=4

<u>Thus, value of n is 4.</u>
