which diol is produced by treatment of trans-2-butene with osmium tetroxide followed by workup with aqueous sodium bisulfite?

The gram formula mass of the product, PCl₃, is 137.5 g.

The amount of a compound that has the same mass in grams as the formula mass in an atomic mass unit is said to have the compound's gram formula mass. It is also known as the molar mass.

Every element's atom has a characteristic mass, and each compound's molecule has a characteristic mass determined by the compound's formula.

The gram formula mass of the product PCl₃ is calculated below:

The atomic mass of P = 31 g

The atomic mass of Cl = 35.5 g

The gram formula mass of PCl₃ = 31 + 35.5 * 3

The gram formula mass of PCl₃ = 137.5 g

To produce 1000 kg of fishmeal (M = 1000 kg), you would need 3000 kg of pasta. To determine the amount of pasta required to produce 1000 kg of fishmeal, we need to consider the mass balance of the process. Let's break down the steps involved:

A. Extraction of fish oil:

The pasta obtained from the extraction stage contains 20% flour and 80% water. To calculate the amount of pasta, we need to determine the mass of flour and water in the pasta. Let's assume the total mass of the pasta is P kg.

Mass of flour = 20% of P = 0.2P kg

Mass of water = 80% of P = 0.8P kg

b. Drying of pasta:

During the drying stage, the pasta is dried in a rotary drum, resulting in fishmeal with 40% humidity. This means that the final fishmeal will contain 60% dry matter.

Let's assume the mass of the dried fishmeal is M kg.

Mass of dry matter = 60% of M = 0.6M kg

Since the dry matter in the fishmeal comes from the flour in the pasta, we can equate the mass of dry matter to the mass of flour:

0.6M kg = 0.2P kg

To produce 1000 kg of fishmeal, we want to find the corresponding value of P:

0.6M = 0.2P

P = (0.6M) / 0.2

P = 3M

Therefore, to produce 1000 kg of fishmeal (M = 1000 kg), you would need 3000 kg of pasta.

Answer:

The answer is C.

Explanation:

i got a 100 on the test

The theoretical yield of carbon dioxide, CO₂ obtained from the reaction is 8.93 g

We'll begin by calculating the mass of citric acid, H₃C₆H₅O₇ that reacted and the mass of carbon dioxide, CO₂ produced from the balanced equation.

H₃C₆H₅O₇ + 3NaHCO₃ —> 3CO₂ + 3H₂O + Na₃C₆H₅O₇

Molar mass of H₃C₆H₅O₇ = (3×1) + (12×6) + (5×1) + (7×16) = 192 g/mol

Mass of H₃C₆H₅O₇ from the balanced equation = 1 × 192 = 192 g

Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol

Mass of CO₂ from the balanced equation = 3 × 44 = 132 g

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂

Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂.

Therefore,

13 g of H₃C₆H₅O₇ will react to produce = (13 × 132) / 192 = 8.93 g of CO₂.

Thus, the theoretical yield of CO₂ is 8.93 g

Explanation:

In living beings the nucleus of each cell contains the genetic information in a molecule called DNA. The DNA is formed by chains of nucleotides, whose order and sequence determine this information.

A DNA molecule forms a chromosome, and this contains genes, corresponding to segments or fractions of the DNA molecule that forms it. This information, contained in the nucleus, is necessary for the construction and functioning of each living being.

Explanation:

The iron concentration is 1.310 M and the sulfate concentration is 1.965M.

We know that ,

Molar mass of Fe2(SO4)3 = 399.88 g/mol

174 ml = 0.174 L

To find molarity,

Molarity = moles solute/liter solution

Moles of solute = 45.6 g x 1 mol/399.88 g

= 0.114 moles Fe2(SO4)3

Molarity (M) = 0.114 moles/0.174 L

= 0.6551 M

We have to find the concentration of each ion ,

Fe2(SO4)3 ==> 2Fe3+ + 3SO42-

[Fe3+] = 2 x 0.6551 M

          = 1.310 M

[SO42-] = 3 x 0.6551 M

           = 1.965 M

Therefore the concentration of ions that is iron is 1.310 M and sulfate is 1.965 M.

28/95 = 29.,5 % of Arsine decomposed

Explanation:A sample of gaseous arsine (AsH3) in a 460 mL flask at 332 Torr and 223 K, is heated to 437 K, at which temperature arsine decom- poses to solid arsenic and hydrogen gas. The flask is then cooled to 273 K, at which tem- perature the pressure in the flask is 488 Torr. What percentage of arsine molecules have de- composed?

Answer in units of %.

initial pressure 332 Torr initial volume 0.46 L initial temperature 223K

final pressure 488 Torr final volume 0.46 L final 273 K

Torr is 1/760 atm 332 torr = 0.437 atm 488 Torr =0.642 atm

PV = nRT so n=RT/PV

INITIAL n= 0.082 X 223/(0.437)(0.46) = 91 moles

final n= 0.082 X 273 / (.437)(488) = 105 moles

2AsH3----------> 2As + 3H2

x moles of Arsine decomposed to make 1.5 moles of H2

the final number of moles was

(91 -X)+ 1.5 X = 105 moles

91 + 0.5 X = 105

0.5 X = 14

X =28

CHECK

if 28 moles of Arsine , then the container would have

91 --28 + 1.5(28) = 91 +14 =105 check

so 28/95 = 29.,5 % of Arsine decomposed

Explanation:

Aluminum oxide or Al2O3 is a chemical compound composed of 3 Oxygen and 2 aluminum atoms. Naturally, it is present in the form of mineral corundum in crystalline polymorphic forms. It holds significant importance in the preparation of Aluminium metal that is used as a refractory material.

To calculate the molar mass of Aluminum oxide, we will add the molar mass of 2 Al and 3 O atoms.

                        Since molar mass of Al is: 26.98 g

                              Molar mass of O is: 16.00 g

                                  Molar mass of Al2O3

                                 =   (26.98)2 +  (16.00) 3

                                    =    53.96 +   48

                                      = 101.96 g/mol

Since it is mentioned in question to round off the answer upto 4 significant figures, it will make the answer: 102.0 g/mol.

Explanation:

This problem is stating a situation in which a solid object is fully immersed in a liquid and the buoyant force is larger that its weight, so that you need to discuss whether this is possible or not.

In general terms, it is necessary to keep in mind that when the buoyant force is larger than its weight, the object will float. On the other side, when the buoyant force is smaller than the weight, then the object will sink.

It means that it could be possible to have this scenario under specific conditions. Now, the Archimedes' principle can be applied with the following version:

\(F_B+W>m_{obj}*a\\\\\rho _{fluid}*V*g+m_{obj}*g>m_{obj}*a\\\\\rho _{fluid}*V-m_{obj}>m_{obj}*a\)

It means that the object can move down the liquid if has a significant acceleration (could be external), even when the buoyant force is larger than the weight

The impact of e-commerce on commercial real estate is significant. E-commerce sales have grown steadily, accounting for a considerable portion of overall sales.

The growth of e-commerce has fueled the demand for distribution spaces, specifically distribution centers and warehouses, which play a crucial role in the supply chain and logistics of packaging and shipping goods to customers. These spaces are sought after by e-commerce giants, who prefer locations near large cities while still providing ample room for large buildings. Suburban areas, such as Katy, Brookshire, and Waller near Houston, are experiencing significant growth in the establishment of distribution centers.

On the other hand, the rise of online shopping has posed challenges for brick-and-mortar retailers. Many physical retail spaces have struggled to remain open or have had to downsize. As a result, there is a trend towards smaller retail spaces, which require less inventory in-store. This trend encourages a combination of online and in-store shopping, known as hybrid shopping. The Covid-19 pandemic further accelerated this trend as consumers sought the convenience and safety of online shopping with options like curbside or in-store pick-up. Even as restrictions ease, this approach is expected to remain popular.

To adapt to the changing retail landscape, integrating technology into physical retail spaces has become crucial. Technology tools, such as mobile apps, can enhance the shopping experience, offer special promotions, and provide valuable data on customer behavior. Retailers, especially large lifestyle shopping centers, have been proactive in blending technology with consumer experiences to stay relevant and attract customers.
