True. The number of molecules in one mole of any substance is the same, the Avogadro number which is 6.022 * 10^23.
<span>After 41.0 min, 41.0% of a compound has decomposed. what is the half-life of this reaction assuming first-order kinetics?</span>
Answer:
F.
Explanation:
Steam is a gas formed when liquid is heated.
The given information in the question is :
Frequency = 170 Hz
1 Hz = 
Frequency = 170 
Wavelength given = 2 m
Speed is unknown which we need to calculate.
Speed can be calculated by using the formula : Speed = wavelength X frequency
By plugging the value of wavelength and frequency in the above formula we get :
Speed = 
Speed = 340
