Explanation:

The way in which the scientist communicates the results of an experiment is through the publication of the scientific article in a scientific journal.

The publication of a scientific or technical article is a way of transmitting to the technical-scientific community the knowledge of new discoveries, and the development of new materials, techniques and methods of analysis in the various areas of science.

Many educational and / or research institutions, and several commercial companies often require their professionals to present the progress of their work and / or study through the publication of technical and scientific articles. In addition, institutions or companies that publish constantly enjoy the technical recognition of their name, which helps to attract greater investments and gains for this organization.

9 g of hydrogen - 42 g of nitrogen
5 g of hydrogen - x g of nitrogen

$9x=42 \cdot 5 \\
9x=210 \\
x \approx 23.33$

The mass of nitrogen in the second sample is 23.33 g.

A liquid-phase isomerization is carried out in a 1000-gal CSTR that has a single impeller located halfway down the reactor. The

igomit [66]

Answer:

The conversion achieved for the first CSTR impeller is 0.382

Discrepancy = 0.188

Explanation:

The impeller divides the CSTR into 2 equal reactors of volume 500gal

Using V = FaoX/ (-ra)

500gal = Fao×Xa/[(KCao^2( 1 -X1)^2]

500gal = CaoVoX1/ KCao^2(1-X1)

500gal= 500gal × X1'/(1 - X1)^2

(1 -X1)^2 = X1

X1^2 - 3X1 + 1 = 0

X1= 0.382

Conversion achieved in the first CSTR is 0.382

Actual measured CSTR = 57% =57/100=0.57

Discrepancy in the conversions= 0.57 -0.383 =0.188
