Answer: Partial pressure of ammonia gas will be 0.36 atm.
Explanation: According to question we have partial pressure values of hydrogen and nitrogen gas with total pressure exerted by the all gases which hydrogen , nitrogen and ammonia. given
= 0.26 atm
= 0.28 atm
= ?
=0.90 atm
+
+
=
..(1)
putting values in (1)
0.26 + 0.28 + = 0.90
= 0.36 atm
Answer: He spends 29.17 hours per week
Explanation:
1 class = 50mins
7 classes = 7 x 50mins = 350mins
For 5 days in a week, we have
5 x 350mins = 1750mins
Converting to hours, we have
1750 /60 = 29.17 hours
There are two possible situations.
1) If a phase change is not occurring, then the heat added contributes to increased translational energy of the particles. What that means is the particles move/vibrate faster.
2) If a phase change is occurring, then the heat added contributes to the breaking of bonds or intermolecular forces (depending on the chemical nature of the matter you're dealing with).
No; it can only ever be at half pressure
hope this helps (;
