I need some help. A helium balloon in a
closed car occupies a
volume of 7.7 liters at 68
degrees
Celsius. It's a hot day and
the temperature rises to 121
degrees Celsius, what is
the
new volume of the balloon?
Always convert
temperature to Kelvin:
(Celsius + 273 =
Kelvin)
A)-8.9 L
B)-09.5L
C)-07.7L
D)-8.2 L

According to the diagram; a) identify the anode of the cell and write the half-reaction that occurs there b) write the overall equation for the reaction that occurs as the cell operates c) calculate the value of the standard cell potential ,e cell. d)write the shorthand notation of the cell above e)indicate the flow of the electrons on the diagram

Displacement is the slope of a velocity vs. time graph a. true b. false

Which states of matter have particles that move independently of one another with very little attraction?
