False, air movement as no control over how quickly it occurs
To solve this we use the
equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
2 M x V1 = 1.50 M x 100 mL
<span>V1 = 75 mL of the 2 M KNO3 solution</span>
1.00mol is the correct answer
Due to the ability of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can reflect radio waves directed into the sky back toward the Earth. Radio waves directed at an angle into the sky can return to Earth beyond the horizon.
I hope this helps !
