protein in foods are broken down into amino acids through what process? Explain your answer.

a. adsorption
b. elimination
c. chemical digestion
d. mechanical digestion

Answers

The answer is c. Because it’s breaking things down

Final answer:

Proteins in food are broken down into amino acids through chemical digestion, a process that takes place mainly in the small intestine with the help of enzymes. This is different from mechanical digestion, which physically breaks down food without changing its chemical composition. The resulting amino acids are then absorbed in the small intestine.

Explanation:

Proteins in foods are broken down into amino acids through the process of chemical digestion. This process involves the reduction of complex proteins into their chemical building blocks, amino acids, which can then be absorbed into the bloodstream to nourish the cells of the body. Most of chemical digestion occurs in the small intestine, particularly in the duodenum, where enzymes break down proteins. It is important to differentiate this process from mechanical digestion, which refers to the physical breakdown of food into smaller pieces through actions such as chewing, without altering the chemical composition of the food.

The absorption of nutrients, primarily in the small intestines, follows digestion. The amino acids, once liberated from the proteins by chemical digestion, are absorbed through the walls of the small intestine and enter the bloodstream for distribution to the body's cells. This process is fundamental because proteins in the diet are not directly absorbed but must first be broken down into their constituent amino acids.

ZnCl2 is used in soldering flux, an alloy used to join two metals together. Determine the moles of Cl- ions in 2.50 mol ZnCl2.

5.00 mol Cl-

0.500 mol Cl-

1.75 mol Cl-

15.0 mol Cl-

Answers

Answer : The number of moles of [tex]Cl^-[/tex] ions are, 5.00 mole.

Explanation :

When 1 mole of [tex]ZnCl_2[/tex] dissociates then it gives 1 mole of [tex]Zn^{2+}[/tex] ion and 2 moles of [tex]Cl^-[/tex] ions.

As we are given that there are 2.50 mole of [tex]ZnCl_2[/tex].

Now we have to determine the number of moles of [tex]Cl^-[/tex] ions.

As, 1 mole of [tex]ZnCl_2[/tex] dissociate to give 2 moles of [tex]Cl^-[/tex] ions.

So, 2.50 mole of [tex]ZnCl_2[/tex] dissociate to give [tex]2\times 2.50=5.00[/tex] moles of [tex]Cl^-[/tex] ions.

Therefore, the number of moles of [tex]Cl^-[/tex] ions are, 5.00 mole.

There are 5.00 moles of Cl- in 2.50 moles of ZnCl2.

We have that the amount of moles of ZnCl2 is equal to 2.50 moles, so, according to the equation that forms this compound we can say that:

                                      [tex]Zn + 2Cl[/tex] ⇒[tex]ZnCl_{2}[/tex]

So, 1 mole ZnCl2 of  decomposes as 1 Zn ion and 2 Cl ions, that is, the number of moles of chlotide is twice the number of moles of ZnCl2:

                                     [tex]2 \times 2.50 = 5.00 moles[/tex]

So, there are 5.00 moles of Cl- in 2.50 moles of ZnCl2.

Which of the following compounds will behave MOST like an ideal gas at higher pressures? a) He b) SO2 c) H2 d) N2 e) F2

Answers

Answer:

Option A

He

Explanation:

Ideal gas: refers to a type of gas having a perfectly elastic collisions between atoms or molecules with no intermolecular attractive forces. Helium is the most ideal gas amongst the given options because it exists as a single atom, with a low boiling point with a very low or even zero intermolecular interaction.

SO2 is less volatile having more intermolecular interaction (van da waal interaction, this is the reason for it's deviation from ideality).

H2 almost behaves like an idea gas because it has a low intermolecular interaction not zero.

N2 is not an ideal gas

F2  is not the most ideal gas.

Final answer:

Helium (He)- (a) is most likely to behave like an ideal gas at higher pressures due to its minimal intermolecular forces and very small atomic radius, which make its behavior under such conditions closer to the assumptions of the ideal gas law.

Explanation:

The compound that will behave most like an ideal gas at higher pressures is helium (He). Ideal gas behavior assumes that there are no intermolecular forces between the gas particles and that the volume of the gas particles themselves is negligible compared to the container. Helium, being a noble gas with a single atomic structure, has minimal intermolecular forces and a very small atomic radius, making it less likely to deviate from ideal behavior even at higher pressures. Furthermore, helium's atoms are significantly smaller than molecules like SO₂, H₂, N₂ or F₂, which means that the volume the particles take up is less significant. Real gases such as SO₂ and F₂ have stronger intermolecular forces due to their larger size and molecular structure, which will cause these gases to deviate from ideal gas behavior more than helium under the same conditions. Therefore, amongst the options provided, helium will behave most similarly to an ideal gas at higher pressures.

A gas sealed in a drum container occupies 7.70 L at a sizzling 325C degrees. What will the volume be if the drum is quickly chilled at 9C degrees.

Answers

The volume of the drum after chilled quickly is 3.6 L.

Explanation:

As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.

[tex]$\frac{V1}{T1} = \frac{V2}{T2} \\[/tex]

After chilling the drum, the volume will get reduced and it can be found as,

V2 = [tex]$\frac{V1T2}{T1}[/tex]

     = [tex]$\frac{7.7 L \times 282 K}{598 K}[/tex]

      = 3.6 L

Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.

You have a 20 gram piece of aluminum and a 40 gram piece of aluminum sitting in the sun. Which piece of aluminum will increase by ten degrees first? What is your evidence and reasoning?

Answers

Since the 2 pieces are made of the same material (aluminum), they have the same specific heat.  Then the piece of lower mass will warm up faster.

ΔT = Q/(mc)

They both receive the same heat transfer Q from the sun,  they both have the same specific heat c, so the one of lower mass m attains the higher temperature rise ΔT over the same time interval.

Final answer:

The 20-gram piece of aluminum will heat up by ten degrees faster than the 40-gram piece because it has less mass. This is based on the properties of heat capacity, represented by the formula for heat transfer Q = mcΔT.

Explanation:

This question is about heat capacity, a concept in physics related to the thermal properties of materials including aluminum. The heat capacity of an object determines how much it will heat up for a given amount of heat applied. It is determined by an object's mass and the specific heat of its material.

As both objects in question are made of aluminum, the specific heat of the material is the same, and thus the only factor that makes a difference is the mass. The heat capacity of an object is proportional to its mass, so a larger object will take longer to heat up. Consequently, the 20-gram piece of aluminum will heat up faster than the 40-gram piece.

This is because less energy is needed to cause a given temperature increase in a smaller mass than in a larger mass, due to the direct proportionality of heat, mass, and temperature change. This is represented by the formula for heat transfer Q = mcΔT, where Q is the heat transferred, m is the mass, c is the specific heat, and ΔT is the change in temperature.

Does the coronavirus have DNA or RNA?

Answers

Answer:

The coronavirus has RNA?

Explanation:

Coronaviruses are important human and animal pathogens and contain an extraordinarily long (27-31 kb) RNA genome. Its RNA synthesis involves complex mechanisms of regulation, similar to those of DNA viruses. In this treatise, mouse hepatitis virus (MHV) is used as a model for the discussion of the mechanism of viral RNA synthesis. We show that MHV RNA synthesis requires interactions of multiple RNA components, which are likely mediated by protein-RNA and protein-protein, as well as RNA-RNA, interactions. This virus also provides a unique example of a discontinuous transcription mechanism, which involves a trans-acting RNA component. Finally, study of the cis-acting signals for the various steps of RNA synthesis revealed an insight into the regulation of viral RNA synthesis. This discussion suggests that the regulation of RNA synthesis in coronavirus is more complex than previously thought possible for RNA viruses. Coronavirus RNA transcription and replication may serve as a paradigm of RNA synthesis for RNA viruses in general.

what is the pressure of 62.76 g of carbon dioxide (CO2) gas if it occupies a volume of

35,000 mL at standard temperature?

Answers

Answer:

P = 995.6 atm

Explanation:

assuming ideal gas:

PV = RTn

∴ Tst = 25°C ≅ 298 K

∴ V = 35.00 mL = 0.035 L

∴ molar mass CO2 = 44.01 g/mol

∴ mass CO2(g) = 62.76 g

⇒ mol CO2(g) = (62.76 g)*(mol/44.01 g) = 1.426 mol

∴ R = 0.082 atm.L/K.mol

⇒ P = RTn/V

⇒ P = ((0.082 atm.L/K.mol)*(298 K)*(1.426 mol)) / (0.035 L)

⇒ P = 995.6 atm

Answer:

The pressure of the carbon dioxide (CO2) gas is 0.913 atm

Explanation:

Step 1: Data given

Mass of carbon dioxide (CO2) = 62.76 grams

Molar mass of carbon dioxide (CO2) = 44.01 g/mol

Volume = 35000 mL = 35 L

Standard temperature = 273 K

Step 2: Calculate moles CO2

Moles CO2 = mass CO2 / molar mass

Moles CO2 = 62.76 grams / 44.01 g/mol

Moles CO2 = 1.426 moles

Step 3: Calculate the pressure

p*V = n*R*T

⇒with p = the pressure of the gas

⇒with V = the volume of the gas = 35 L

⇒with n = the moles of the gas = 1.426 moles

⇒with R = the gas constant = 0.08206 L*atm/mol *K

⇒with T = the temperature = 273 K

p = (n*R*T) / V

p = (1.426 * 0.08206 * 273) / 35

p = 0.913 atm

The pressure of the carbon dioxide (CO2) gas is 0.913 atm

Answers

Answer:

A

Explanation:

With chemical reactions, there are various factors that affect the rate of the reaction. One of these is temperature.

When you raise the temperature, the reaction will move faster. Why? Temperature is directly correlated with the kinetic energy (basically, the energy that makes the particles move). Higher temperatures mean higher kinetic energies. Particles with higher kinetic energies move faster, which makes them more likely to collide. When collisions occur more frequently, the reaction follows through more quickly.

Thus, when Julissa warms the solutions, she will see that bubbling and white solid formation (the products of the reaction) occus faster. So, the answer is A.
