Answer:

The answer to your question is:  68.3%

Explanation:

Urea = ?

Theoretical yield

Ammonia 145.1 kg

Carbon dioxide = 211.4 kg

Urea = 174.9 kg

MW NH3 = 17kg

MW CO2 44 kg

MW Urea = 60 kg

                     2NH₃(aq)     +    CO₂(aq)    →     CH₄N₂O(aq)    +     H₂O(l)

                     34                        44 kg                 60kg

                    145.1                   211.4                   174.9

Limiting reactant = NH3

                   34kg of NH3 ------------------ 60 kg of Urea

                    145.1 kg       -------------------   x

                 x = (145.1 x 60) / 34

                x = 256 kg of Urea

Percent yield = 174.9 / 256 x 100

                     = 68.3%

In the naturally occurring D series of ketoses, the carbonyl group is found on carbon number ___________, whereas in aldoses, th
Elena-2011 [213]

Answer:

second carbon atom from the  end

end carbon atom

Explanation:

Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygen. The general molecular formula of Carbohydrates is C_x(H_2O)_y.

Carbohydrates can be classified based on structures,

Carbohydrates with the structure of alkanals (-CHO) are known as aldose while those of the structure of alkanones (C=O) are known as ketose.

In stereochemistry , D series is a kind of configurational arrangement where the hydroxyl group attaches itself to the right hand side.

Thus; in naturally occurring D series of ketoses, the carbonyl group is found on carbon number <u>second carbon atom from the  end </u>whereas in aldoses, the carbonyl group is found on carbon number <u> end carbon atom.</u>

What is true of intercellular signals that do not go through direct connections between cells, such as plasmodesmata?
Ronch [10]

I believe that what happens here is that when those cells carrying those intercellular signals do no pass through the connections, actually the signal is passed through or are transferred to adjacent cells for signal transmission, hence the answer is:

What did J.J. Thomson discover about the atom that changed the atomic model previously used?
galina1969 [7]
J.J. Thomson hypothesized and discovered that the atom was not the smallest unit of matter but that instead there were much smaller units. He discovered "sub-atomic particles" which make up atoms. The sub-atomic particle that Thomson discovered was the electron. He discovered this through a process of experiments testing cathode rays.
