The heat released from the calculation is 33.56 kJ.

<h3>Heat of vaporization</h3>

The heat of vaporization is the heat absorbed when a substance changes from liquid to vapor. It is equal to the heat released when the vapor is condensed.

The total heat released = Heat of condensation + Heat lost to the skin

=  (13.3 g × 2260 J/g) + (13.3 g × 4.18 J/g/°C  × ( 100 - 37)°C)

= 30058 + 3502

= 33.56 kJ

The heat released from the calculation is 33.56 kJ.

How can the conductivity of a salt solution be decreased?
Musya8 [376]

Answer:

B. Add more water to decrease the concentration.

Explanation:

If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.

  • Concentration is the amount of solute in a solution.
  • Conductivity deals with the ability of a solution to allow the passage of current.

Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.

  • Adding more water increases the amount of solvent and the concentration reduces.

nadezda [96]

Answer:

0.35 milli moles of ethanol can be theoretically be produced under these conditions.

Explanation:

C_6H_{12}O_6 + 2 ADP + 2 Pi\rightarrow 2 C_2H_5OH + 2 ATP + 2 CO_2

Moles of glucose = 3.50\times 10^2 milli mole

Moles of ADP = 0.35 milli mole

Moles of Pi = 0.35 milli mole

Moles of ATP = 0.70 milli mole

As we can see that ADP and Pi are in limiting amount which means tat they are limiting reagent. So, the moles of ethanol produced will depend upon the moles of ADP and Pi.

According to reaction, 2 moles of ADP gives 2 moles of glucose.

Then 0.35 milli moles of ADp will give :

\frac{2}{2}\times 0.35 mmol=0.35 mmol of ethanol

0.35 milli moles of ethanol can be theoretically be produced under these conditions.
