What is the factor that changes the reaction rate in the following example and why:
Wine sours more slowly when stored in closed bottles.

Answers

Answer 1

Answer:

The factor is called a "catalyst." The wine sours more slowly when stored in closed bottles because there's no "oxygen" inside the bottle that could lead to an increase rate of decomposition.

Explanation:

Wines are naturally stored with a cork. The cork prevents oxygen from entering into the bottle. As you probably know, wines have natural bacteria which play a role in the process of fermentation. Once bacteria are introduced to oxygen, they multiply. However, in the process of fermentation, there's no oxygen present. So, once the bottle of wine is opened, it should be consumed immediately because exposing it to air will change its flavors.

A "catalyst" is a factor that affects reaction rates. Their presence hastens the time for decomposition.

In fermentation, what do cells use instead of oxygen to break down glucose?

Answers

Answer:

sugar

Explanation:

In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation. Fermentation doesn't break the sugar down any further, it simply helps reset the system so that more sugar can be broken down.

Cells use sugar instead of oxygen to break down glucose.

The cell employs a phenomenon known as anaerobic fermenting throughout the oxygen-free environment. or just fermentation. Fermentation does not in any way break down the sugar; it only gently serves to refresh the mechanism because then additional sugar may very well be decomposed as well as subdivided.

Thus the above response is right.

When an electron beam strikes a block of copper, x-rays of frequency 6 x 10^18 Hz are emitted. What is the wavelength of these x-rays? Answer in units of pm.

Answers

Answer:

0.5×10² pm

Explanation:

Given data:

Frequency of x-ray = 6×10¹⁸ Hz

Wavelength of x-ray = ?

Solution:

Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.

Formula:

speed of wave = wavelength × frequency

speed = 3×10⁸ m/s

now we will put the values in formula.

3×10⁸ m/s = λ  × 6×10¹⁸ Hz

Hz = s⁻¹

λ  = 3×10⁸ m/s / 6×10¹⁸ s⁻¹

λ  = 0.5×10⁻¹⁰ m

m to pm

0.5×10⁻¹⁰ m × 10¹² pm/1m

0.5×10² pm

Diffusion of Ammonia in an Aqueous Solution. An ammonia (A)-water (B) solution at 278 K and 4.0 mm thick is in contact at one surface with an organic liquid at this interface. The concentration of ammonia in the organic phase is held constant and is such that the equilibrium concentration of ammonia in the water at this surface is 2.0 wt 'Yo ammonia (density of aqueous solution is 991.7 kg/m3) and the concentration of ammonia in water at the other end of the film 4.0 mm away is 10 wt % (density of 961.7 kg/m3). Water and the organic are insoluble in each other. The diffusion coefficient ofNH3 in water is 1.24 x 10- 9 m 2/sCalculate the flux N_B. Explain.

Answers

Answer:

The Flux N_B = 0

Explanation:

So, we are given the following set of data or parameters which is going to help in solving this particular Question. So, let us take each at a time;

=> "An ammonia (A)-water (B) solution at 278 K and 4.0 mm thick is in contact at one surface with an organic liquid at this interface."

=>" 2.0 wt 'Yo ammonia (density of aqueous solution is 991.7 kg/m3) and the concentration of ammonia in water at the other end of the film 4.0 mm away is 10 wt % (density of 961.7 kg/m3). ''

With the information above, we can determine the N_A(which the question did not specify that we should calculate).

For the value of N_B, it will be equals to zero(0) because the insolubility of water in organic solvent.

Answers

Answer:

The answer is 87.21 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{5.25 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 87.2093023...[/tex]

We have the final answer as

87.21 moles
