A solution of aminoheptanoic acid, H2N-(CH2).COOH, in m-cresol at a concentration of 3.3 mol amino acid per kg of solution is po

garik1379 [7]

Explanation:

The given data is as follows.

Concentration = 3.3 mol

Rate constant = $2.74 \times 10^{3} kg/mol min$

Molecular weight = 55000 g/mol

$\tau = C_{A_{0}} \times \int_{0}^{X_{A}} \frac{dX_{A}}{-r_{A}}$

Initial concentration ( $C_{A_{0}}$ ) of aminoheptanoic is 3.3 kg/mol.

$-r_{A} = 2.74 \times 10^{3} kg/mol min$

Hence, putting the given values into the above formula as follows.

$\tau = C_{A_{0}}\times \int_{0}^{X_{A}} \frac{dX_{A}}{-r_{A}}$

= $\frac{3.3}{2.74 \times 10^{3} kg/mol min} [X_{A}]^{0.1}_{0}$

= 120.43 min

Thus, we can conclude that total time required to to form polyamide is 120.43 min.

What is the mole fraction of potassium dichromate, K2Cr2O7, in a solution prepared from 24.42 g of potassium dichromate and 240.

Harrizon [31]

Answer:

$6.19\times 10^{-3}$ is the mole fraction of potassium dichromate.

Explanation:

Mass of potassium dichromate = 24.42 g

Moles of potassium dichromate = $n_1=\frac{24.42 g}{294.185 g/mol}=0.0830 mol$

Mass of water = 240.0 g

Moles of water = $n_2=\frac{240.0 g}{18.015 g/mol}=13.3222 mol$

Mole fraction is calculated by:

$\chi_1=\frac{n_1}{n_1+n_2}$

$\chi_1=\frac{0.0830 mol}{0.0830 mol+13.3222 mol}=0.00619=6.19\times 10^{-3}$

$6.19\times 10^{-3}$ is the mole fraction of potassium dichromate.

An organic compound must meet the requirements of having both Carbon and Hydrogen bound to one another. As you can see, CO2 is the only compound that is not organic because it lacks hydrogen in it. All the other compounds have at least 4 Hydrogens and is the reason why they are an Organic Compound.
