Answer:
The partial pressure is
Explanation:
The Partial pressure of is mathematically represented as
Where is the total pressure of water with a value of 15.5 mm of Hg
is the partial pressure of water with a value 753 mm of Hg
Now substituting values
Answer:
6 moles
Explanation:
You have a 1:3 ratio between nitrogen gas and hydrogen gas
The final temperature in Celsius of the metal block is 49°C.
<h3>How to find the number of moles ?</h3>
Moles water =
=
= 0.0266 moles
Heat lost by water = 0.0266 mol x 44.0 kJ/mol
= 1.17 kJ
= 1170 J [1 kJ = 1000 J]
Heat lost = Heat gained
Heat gained by aluminum = 1170 J
1170 = 55 x 0.903 (T - 25) = 49.7 T - 1242
1170 + 1242 = 49.7 T
T = 48.5°C (49°C at two significant figures)
Thus from the above conclusion we can say that The final temperature in Celsius of the metal block is 49°C.

Answer:
Explanation:
A. The ripening of a banana
Ripening of banana releases ethene is a gas which increases the entropy of the system.
B. Dissolution of sugar in a cup of hot coffee
Solid sugar will dissolve in aqueous medium to be liberate sugar molecules and is more distributed throughout the hot coffee, thus an increase in the entropy of the system.
C. The reaction of nitrogen atoms to form N2 molecules at 25 degree C and 1 atm. It takes two atoms to form 1 molecule of N2
A decrease in the number of the particles leads to a decrease in the entropy of the system.
D. Lightning
The process of lightning is from ions coming together to releases energy in the form of light. Thus the system has less energy leading to a decrease in the energy distribution and a decrease in the entropy of the system.
E. Formation of CH4 and O2
CO2 and H2O at room temperature and 1 atm of pressure is a gas while H2O exits as a liquid. When CH4 and O2 are formed, they will both be in the gas phase. Change of phase from Liquid to gas increases the entropy of the system.
