Use the combined gas law (convert temperatures to Kelvin first).
P1V1/T1 = P2V2/T2
P1 = 0.5 atm
V1 = 143 mL
T1 = 35.0°C = 308 K
P2 = 1 atm
V2 = ?
T2 = 0°C = 273 K
Solve the equation for V2 and you get:
V2 = P1V1T2/T1P2 = (0.5 atm)(143 mL)(273 K) / (308 K)(1 atm) = 63.4 mL
C. 63.4 mL
Astrophysics
and planetar Astrophysics and planetary science are considered
subspecialties of Astronomy. Astronomy is the study of the sun, moon,
planets, stars, comets, gas, galaxies, dust and other bodies and
phenomena.
Note
Astrophysics
- properties of space
Planetary
Science - planet formation

Answer:
The experimental feature of the MALDI-MS technique which allows the separation of ions formed after the adduction of tissue molecules:
B) Velocity of ions depends on the ion mass-to-charge ratio.
Explanation:
- The option a is not correct as distance traveled by ions doesn't depend upon the ion charge rather it depends upon time for which you leave the sample to run.
- The option b is correct as velocity of ions depends on the ion mass-to-charge ratio because separation is done due to mass to charge ratio feature.
- The option c is incorrect as time of travel is not inversely proportional to the ion-to-mass ratio because the ion will move across the gel until you stop the electric field.
- The option d is not correct as electric field between MALDI plate and MS analyzer is though uniform but this feature doesn't allow the separation of ions.
Answer:
to keep the surfer from slipping off the board
Explanation:
Surfboard wax (also known as surfwax) is a formulation of natural and/or synthetic wax for application to the deck of a surfboard, bodyboard, or skimboard, to keep the surfer from slipping off the board when paddling out or riding a wave. It is also used to increase grip on the paddle of a surf kayak or dragon boat.
Answer:
D. It contains a phosphate with higher phosphoryl transfer potential than ATP
Explanation:
1,3-Bisphosphoglycerate contains a phosphate group that has high phosphoryl transfer potential than ATP (they can transfer the phosphoryl group to ATP). Other high phosphoryl transfer potential groups include :Creatine kinase and phosphoenolpyruvate.
