How many grams of iron(III) oxide (Fe(OH)3) may theoretically be produced from 85.0 g FeCl3?

Chemistry

Crank3 years ago
8 0

Answer:

56.0 g

Explanation:

Calculation of the moles of FeCl_3 as:-

Mass = 85.0 g

Molar mass of FeCl_3 = 162.2 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{85.0\ g}{162.2\ g/mol}

Moles= 0.52404\ mol

According to the reaction:-

FeCl_3+3 NaOH\rightarrow Fe(OH)_3+3 NaCl

1 mole of FeCl_3 on reaction forms 1 mole of Fe(OH)_3

Also,

0.52404 mole of FeCl_3 on reaction forms 0.52404 mole of Fe(OH)_3

Moles of Fe(OH)_3  = 0.52404 moles

Molar mass of Fe(OH)_3  = 106.867 g/mol

Mass = Moles*Molar mass = 0.52404\times 106.867\ g = 56.0 g

What is the [OH-] of a substance that has a pH of 11?
Deffense [45]

Answer:

0.001 M OH-

Explanation:

[OH-] = 10^-pOH, so

pOH + pH = 14 and 14 - pH = pOH

14 - 11 = 3

[OH⁻] = 10⁻³ ; [OH-] = 0.001 M OH-

A 2.04 g lead weight, initially at 10.8 oC, is submerged in 7.62 g of water at 52.3 oC in an insulated container. clear = 0.128
alisha [4.7K]

Answer: The final temperature of both the weight and the water at thermal equilibrium is 50.26^{o}C.

Explanation:

The given data is as follows.

mass = 7.62 g,           T_{2} = 10.8^{o}C

Let us assume that T be the final temperature. Therefore, heat lost by water is calculated as follows.

       q = mC \times \Delta T    

          = 7.62 g \times 4.184 J/^{o}C \times (52.3 - T)

Now, heat gained by lead will be calculated as follows.

       q = mC \times \text{Temperature change of lead}  

           = 2.04 \times 0.128 \times (T - 11.0)

According to the given situation,

     Heat lost = Heat gained

7.62 g \times 4.184 J/^{o}C \times (52.3 - T) = 2.04 \times 0.128 \times (T - 11.0)

        T = 50.26^{o}C

Thus, we can conclude that the final temperature of both the weight and the water at thermal equilibrium is 50.26^{o}C.
