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 charge dose an atom have? pls have a claim,Evidence,Reasoning

Andre45 [30]

An atom typically has a neutral charge, as in most cases an atom has the same amount of positively charged protons as it does negatively charged electrons.

Atoms that do not have the same amount of electrons as protons are known as isotopes.
