Cranberries and grapes may have therapeutic value. A cranberry company obtained the patent for a process to extract the oil from

cranberry seeds. According to the patent, this oil can be used to treat breast cancer or to reduce its incidence. The oil can be used in drinks and foods. A grape juice company claims to have evidence that certain grapes have health benefits ranging from improving cardiovascular health to improving cognitive brain function in the elderly. These claims will be tested by the Food and Drug Administration (FDA) before the companies are allowed to market their products for “treating” ailments or “improving” health. Until then, the companies can describe that their products “help to maintain” or “support” health. Until studies support their claims, the companies cannot ascribe direct health benefits to their products.
Why would the FDA perform tests when a cranberry company and a grape company have already conducted research on the same products?

A. The FDA is the only organization that can test if health actually improves.

B. Tests that are performed by any company which benefits financially are considered unreliable.

C. The FDA tests give reliability to the results of improved health obtained by each company.

D. Tests performed by the FDA follow established scientific methods, but those performed by companies do not.

Answer is: C. The FDA tests give reliability to the results of improved health obtained by each company.

The FDA (The Food and Drug Administration) is a federal agency of the United States Department of Health and Human Services.

The FDA controls food safety, tobacco products, dietary supplements, prescription, pharmaceutical drugs, vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices, cosmetics and animal food.

Answer:

615 g

Explanation:

In order to convert from moles of any given substance into grams, we have to use said substance's <em>molar mass</em>, as follows:

  • # moles * Molar mass = grams of substance.

Thus, we now <u>calculate the molar mass of beryllium iodide</u>, BeI₂, using the <em>molar masses of the elements</em>:

  • Molar Mass of BeI₂ = Molar Mass of Be + (Molar Mass of I)*2 = 262.821 g/mol

Finally we <u>calculate how many grams are there in 2.34 moles of BeI₂</u>:

  • 2.34 mol * 262.821 g/mol = 615 g

4. A sample of gas has a pressure of 700 mmHg and 30.0°C. Ar what temperature would the pressure be 600 mmHg if the volume remai
shtirl [24]

Answer:

T₂  = 259.84 K

T₂  = -13.31 °C

Explanation:

Given data:

Initial pressure = 700 mmHg

Initial temperature = 30.0°C (30+273.15 K = 303.15 K)

Final temperature = ?

Final pressure = 600 mmHg

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

700 mmHg /303.15 K  = 600 mmHg / T₂

T₂  = 600 mmHg × 303.15 K / 700 mmHg

T₂  =181890 mmHg.K /700 mmHg

T₂  = 259.84 K

Temperature in celsius

259.84 K - 273.15 = -13.31 °C

Use the particle theory to explain,liquid to soild process
hjlf

The liquid to solid process  using the particle theory is as below


  • The process  that involve  change    of liquid to solid  is known as  Freezing
  • It involve  change from a high energy state to lower energy
  • The constant  temperature at  which  a liquid change to solid by giving  out heat energy is called freezing point  of the liquid
  • when  liquid are cooled  the thermal energy  of  particles  decrease.
  • The cohesive forces  between  the  particles strengthen  to such extent  that particles  can have relative motion with each other and they occupy the fixed position, thus liquid is converted to solid

The reaction converting glycerol to glycerol-3-phosphate can be represented as: glycerol + hpo42− ⟶ glycerol-3-phosphate + h2o.
Volgvan

Answer;

Yes; this reaction be spontaneous if coupled with the hydrolysis of ATP.

Explanation;

The reaction converting glycerol to glycerol-3-phosphate (energetically unfavorable) can be coupled with the conversion of ATP to ADP (energetically favorable):

Glycerol + HPO42 ⟶glycerol-3-phosphate+H2O

ATP + H2O⟶ ADP + HPO42− + H+
