Answer:
0.371
Explanation:
number of moles = mass / Ar
= 23.8g / 32.1 + (16.0 × 2)
= 0.37129485179 = 0.371 (3 s.f).
hope it helps :)
There are three methods of heat transfer
Answer:
a. Cellular Respiration produces more ATP than Anaerobic Respiration.
Explanation:
Cellular Respiration creates a total of 36-38 ATP per round. Anaerobic processes only produce 2 ATP per cycle.
Answer: Option (a) is the correct answer.
Explanation:
The given data is as follows.
= 4.19 
= 1.9 
Heat of vaporization (
) at 1 atm and
is 2259 kJ/kg
= 0
Therefore, calculate the enthalpy of water vapor at 1 atm and
as follows.
=
+
= 0 + 2259 kJ/kg
= 2259 kJ/kg
As the desired temperature is given
and effect of pressure is not considered. Hence, enthalpy of liquid water at 10 bar and
is calculated as follows.
= 
= 334.781 kJ/kg
Hence, enthalpy of water vapor at 10 bar and
is calculated as follows.

=
= 2410.81 kJ/kg
Therefore, calculate the latent heat of vaporization at 10 bar and
as follows.
=
= 2410.81 kJ/kg - 334.781 kJ/kg
= 2076.029 kJ/kg
or, = 2076 kJ/kg
Thus, we can conclude that at 10 bar and
latent heat of vaporization is 2076 kJ/kg.
