Answer:
The new volume at -29°C and 432 torr is 6.51 L
Explanation:
Step 1: Data given
Initial volume of CO = 4.63 L
Initial temperature = 296.0 K
Initial pressure = 737 torr = 737/760 = 0.9697 atm
Step 2: Calculate the new volume
(P1*V1)/T1 = (P2*V2)/T2
V2 = (P1V1*T2) / (T1*P2)
⇒ with P1 = the initial pressure = 0.9697 atm
⇒ with V1 = the initial volume = 4.63 L
⇒ with T1 = The initial temperature = 296.0 K
⇒ with T2 = the new temperature = -29.0 + 273 = 244 K
⇒ with P2 = the new pressure = 432/760 = 0.5684 atm
V2 = (P1V1/T1) * (T2/P2)
V2 = 6.51 L
The new volume at -29°C and 432 torr is 6.51 L
Answer:
33/16 S
Explanation:
In beta decay, the atomic number of the daughter nucleus increases by one unit while the mass of the daughter nucleus remains the same as that of the parent nucleus.
Hence, if we know that a beta decay has occurred, then the parent nucleus must have the same mass as its daughter nucleus but have an atomic number that is less than that of the daughter nucleus by only one unit, hence the answer above.
Answer:
Cell Type I: Animal cell surrounded by a plasma membrane only.
Cell Type II: Plant cell surrounded by a plasma membrane and a cell wall.
Explanation:
Hello,
In this case, we must remember that animal cells are covered only by a plasma membrane, which is not enough to keep the cell from bursting as no limit for the inlet salt is established, causing it both to swell and burst. On the other hand, plant cells are covered by both a plasma membrane and a cell wall which contributive effect allow the inlet of the salt but prevent the cell to burst as the cell wall is rigid. In such a way, based on the described situation, one infers that the cell type I is an animal cell surrounded by a plasma membrane only the cell type II is a plant cell surrounded by a plasma membrane and a cell wall.
Best regards.
The first scientist to show that atoms emit tiny negative particles was J. J. Thomson.
