A "fizz-keeper" is a small air pump that you can place on an opened soda bottle. When operated the pump is used to pressurize th

e air space above the soda by pumping in air from the outside. Based on Henry's law, this would be expected to __________ the solubility of carbon dioxide in the remaining soda.

Answer: increase

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

As soda contains carbon dioxide dissolved in water.

The equation given by Henry's law is:

C_{CO_2}=K_H\times p_{CO_2}

where,

C_{CO_2} = solubility of carbon dioxide in water

K_H = Henry's constant

p_{CO_2} = partial pressure of carbon dioxide

Thus on increasing the pressure, the solubility of carbon dioxide also increase.

How much heat must be absorbed by 125 g of ethanol to change its temperature from 21.5 ∘C to 34.8 ∘C? (Specific heat capacity of
Katarina [22]

Answer:

Option D. 4.02 kJ

Explanation:

A simple calorimetry problem

Q = m . C . ΔT

ΔT = Final T° - Initial T°

C = Specific heat capacity

m = mass

Let's replace the data

Q = 125 g . 2.42 J/g∘C . (34.8°C -21.5 °C)

Q= 4023.25 J

We must convert the answer to kJ

4023.25 J . 1kJ /1000 =4.02kJ

In E. coli, the enzyme hexokinase catalyzes the reaction: Glucose + ATP → glucose 6-phosphate + ADP The equilibrium constant, Ke
kondor19780726 [428]

Answer:

Explanation:

Glucose + ATP → glucose 6-phosphate + ADP The equilibrium constant, Keq, is 7.8 x 102.

In the living E. coli cells,

[ATP] = 7.9 mM;

[ADP] = 1.04 mM,

[glucose] = 2 mM,

[glucose 6-phosphate] = 1 mM.

Determine if the reaction is at equilibrium. If the reaction is not at equilibrium, determine which side the reaction favors in living E. coli cells.

The reaction is given as

Glucose + ATP → glucose 6-phosphate + ADP

Now reaction quotient for given equation above is

q=\frac{[\text {glucose 6-phosphate}][ADP]}{[Glucose][ATP]}

q=\frac{(1mm)\times (1.04 mm)}{(7.9mm)\times (2mm)} \\\\=6.582\times 10^{-2}

so,

q ⇒ following this criteria the reaction will go towards the right direction ( that is forward reaction is favorable  until q = Keq
