Well...........thanks for posting anyway.
B. Don't take up most of the space in an atom,
Answer:
a. What is the wavelength?
The wavelength is 5 meters.
b. What is the frequency?
The frequency is 0.05Hz
c. What is the wave velocity?
The wave velocity is 0.25 meters per second
Explanation:
the wavelength is the distance between two troughs or two crests, which in this case is 5 meters.
the frequency=cycles/time. For this equation the equation would be 1/20, which is 0.05
the wave velocity=wavelength x frequency. Plug in the numbers, 5 x 0.05, and you will get 0.25.
Mole number of 75 g is 0.4 mol. NO2 is 0.8 mol and is 36.8 g.
