Look up and compare the ionic radii of In3+, Mn3+, and Y3+ for a specific coordination number. Why do you think Mn3+ forms a sol

id substitution on the In3+ rather than the Y3+ site?

Answer:

See explanation

Explanation:

Substitution implies that one thing is repalced by the other.

Substitution of one ion by another largely depends on the sizes of the ions in question.

The ionic radius of Mn3+ is about 0.65 Angstroms while that of In3+ is about 0.94 Angstroms. On the other hand, the ionic radius of Y3+ is about 1.032 Angstroms.

It is clear that the sizes of Mn3+ and In3+ are closer to each other hence Mn3+ can substitute for In3+ easily than Y3+ in a lattice site.

The larger size of Y3+ explains why it is not easily replaced by Mn3+.

Alinara [238K]

Explanation:

La ciencia puede entenderse como una forma que el ser humano encontró para adquirir conocimientos a través de métodos científicos, tecnológicos y basados ​​en estudios, pruebas e investigaciones y no basados ​​en el pensamiento para explicar los fenómenos humanos, de la naturaleza y de la vida.

La ciencia tiene un rol impactante y transformador en la sociedad, todo el conocimiento adquirido por el hombre a través de la ciencia ha transformado para mejor la vida de las personas, generando mayor calidad de vida, salud, educación, sentido crítico, etc.

En el escenario pandémico que vive el mundo actualmente, la ciencia es fundamental, a través de sus estudios e investigaciones que han ayudado en el desarrollo de vacunas efectivas para inmunizar a los humanos contra el virus y salvar vidas.

iron is made by a reduction of iron oxide with carbon monoxide. Fe2O3+3CO-2Fe+3CO2. Calculate the mass of iron that can be forme
lyudmila [28]

Answer:

Mass = 88.12 g

Explanation:

Given data:

Mass of iron oxide = 126 g

Mass of iron formed = ?

Solution:

Chemical equation:

Fe₂O₃ + 3CO    →      2Fe + 3CO₂

Number of moles of iron oxide:

Number of moles = mass/molar mass

Number of moles = 126 g/ 159.69 g/mol

Number of moles = 0.789 mol

Now we will compare the moles of iron with iron oxide.

                      Fe₂O₃           :             Fe

                         1                 :               2

                   0.789              :            2/1×0.789 = 1.578 mol

Mass of iron:

Mass = number of moles ×molar mass

Mass = 1.578 mol × 55.84 g/mol

Mass = 88.12 g

What is the equilibrium partial pressure of water vapor above a mixture of 62.9 g H2O and 33.2 g HOCH2CH2OH at 55 °C. The partia
bija089 [108]

Answer : The partial pressure of H_2O is 102.3 mmHg.

Explanation :

As per question,

Mass of H_2O = 62.9 g

Mass of HOCH_2CH_2OH = 33.2 g

Molar mass of H_2O = 18 g/mole

Molar mass of HOCH_2CH_2OH = 62 g/mole

First we have to calculate the moles of H_2O and HOCH_2CH_2OH.

\text{Moles of }H_2O=\frac{\text{Mass of }H_2O}{\text{Molar mass of }H_2O}=\frac{62.9g}{18g/mole}=3.49mole

\text{Moles of }HOCH_2CH_2OH=\frac{\text{Mass of }HOCH_2CH_2OH}{\text{Molar mass of }HOCH_2CH_2OH}=\frac{33.2g}{62g/mole}=0.536mole

Now we have to calculate the mole fraction of H_2O and HOCH_2CH_2OH.

\text{Mole fraction of }H_2O=\frac{\text{Moles of }H_2O}{\text{Moles of }H_2O+\text{Moles of }HOCH_2CH_2OH}=\frac{3.49}{3.49+0.536}=0.867

\text{Mole fraction of }HOCH_2CH_2OH=\frac{\text{Moles of }HOCH_2CH_2OH}{\text{Moles of }H_2O+\text{Moles of }HOCH_2CH_2OH}=\frac{0.536}{3.49+0.536}=0.134

Now we have to partial pressure of H_2O.

According to the Raoult's law,

p^o=X\times p_T

where,

p^o = partial pressure of water vapor

p_T = total pressure of gas

X = mole fraction of water vapor

p_{H_2O}=X_{H_2O}\times p_T

p_{H_2O}=0.867\times 118.0mmHg=102.3mmHg

Therefore, the partial pressure of H_2O is 102.3 mmHg.
