Question

Will Fan and Medal just need help double checking easy chem questions.

Answer 1

Lol. Ok.....

Answer 2

1. Standard atmospheric pressure corresponds to the normal air pressure at sea level.
a. True
b. False

i said true

Answer 3

2. Which of the following shows the correct setup in converting 234 kilopascals to torr?

i said 234 kPa (760 Torr / 101.325 kPa)

Answer 4

@abb0t @jigglypuff314 @StudyGurl14

Answer 5

Yeah. You're right.

Answer 6

3.If the volume of a container is increased, the pressure of the gas in the container also increases (when the amount of gas and temperature are held constant)

i said false

Answer 7

4.To keep the pressure and temperature of a gas constant, the volume of the gas canister must remain constant as additional moles of gas are added.

i said false for this one too

Answer 8

I think youre right on those too

Answer 9

okay for 5. If the volume and moles of a container are held constant, the temperature of a gas is inversely proportional to the pressure.

i put false

Answer 10

6. If the moles and temperature of a gas are held constant, the pressure of a gas doubles when:

i put volume is doubled

Answer 11

5. youre right
6 it dounbles when the volume is halved. if you double the volume, the space for the molecules to move around in doubles, then the pressure lessensas they can move around moe and are not hitting the walls of the container as hard and fast

Answer 12

oh okay that makes sense thanks

Answer 13

7. A balloon containing 0.10 moles of gas has a volume of 2.00 liters. If temperature and pressure remain constant, the new volume will be 3.00 liters when you add 0.15 moles of gas to the balloon.

i said true

Answer 14

8. When using the ideal gas constant value, R = 0.0821, in an ideal gas law calculation, the units of pressure may be expressed in units of atmospheres or kilopascals.

i said false

Answer 15

I think youre right on both of those

Answer 16

cool those are all of em :)
thanks for your help!

Answer 17

youre welcome :-) im in Colo CA and we just did the gas laws :-)
