The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed 3RT rms speed = where R = 8.314 J/(mol·K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg-m²/s?). What is the rms speed of F, molecules at 305 K? rms speed: m/s What is the rms speed of He atoms at 305 K? rms speed: m/s

An electric current of 21.50 A flows for 21.0 minutes. Calculate the amount of electric charge transported.. Be sure your answer has the correct unit symbol and 3 significant digits. 7 x10 •O U 89 S

These are two separate questions.

Which statement is true?   Question 12 options:    Precision is measured by standard deviation.   Precision is measured by error or relative error.   Accuracy is measured by the standard deviation.

for forensic chemistry :  If a vehicle with four wheels is traveling in a linear path through soft dirt, how many and which tires would you expect to leave tire track impressions?
