Question

Which of the following formulas is consistent with the unit cell of the rhenium oxide compound shown below? (A) Re 2 O 6 (B) Re 2 O 3 (C) ReO 6 (D) ReO

Tardigrade Admin · Accepted Answer

Effective number of rhenium =(1/8) × 8=1 Effective number of oxygen =12 × (1/4)=3 ∴ Formula = ReO 3 or Re 2 O 6

Q. Which of the following formulas is consistent with the unit cell of the rhenium oxide compound shown below?

$R e_{2} O_{6}$

$R e_{2} O_{3}$

$R e O_{6}$

$R e O$

Effective number of rhenium $= \frac{1}{8} \times 8 = 1$
Effective number of oxygen $= 12 \times \frac{1}{4} = 3$
$∴$ Formula $= R e O_{3}$
or $R e_{2} O_{6}$

Q. Which of the following formulas is consistent with the unit cell of the rhenium oxide compound shown below?

Re2​O6​

Re2​O3​

ReO6​

ReO

Effective number of rhenium =81​×8=1 Effective number of oxygen =12×41​=3 ∴ Formula =ReO3​ or Re2​O6​

$R e_{2} O_{6}$

$R e_{2} O_{3}$

$R e O_{6}$

$R e O$

Effective number of rhenium $= \frac{1}{8} \times 8 = 1$
Effective number of oxygen $= 12 \times \frac{1}{4} = 3$
$∴$ Formula $= R e O_{3}$
or $R e_{2} O_{6}$
