Answer:
7.22L
Explanation:
At Stp T2 = 273K and P2 is 1 atm
So we have the following data
V1 =10L. P1=650mmHg(0.855atm)
V2 =V2. P2 = 1 atm
T1=50°c (323K) T2 =273K
Hence from the combined gas law
P1xV1 /T1 =P2xV2/T2
0.855x10/323 =1xV2 /273
8.55/323 =V2 /273
V2 = 8.55x273 /323
V2 = 7.226 L
Answer:
The waves travel in a direction parallel to direction of the vibration of the medium
Crystallize below earths surface
Q=mcΔT
q=(125g)(0.446 J/(g x °C))(78°C - 23.5°C)
q=(125 g)(0.446 J/(g x °C))(54.5°C) (Be sure to cancel all similar units)
q= 3038.375 J
The number of neutrons in an atoms nucleus can be calculated by subtracting the atomic number of that atom from its mass number.
