Explanation:
During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. El Niño can
If you’re referring to H vs H2,
H is usually found in ion form as H+
H2 is the designation for pure hydrogen gas, as it is diatomic and can only exist on its own in nature if it’s bonded to another H atom.
In this case, H is an ion and H2 is hydrogen gas
The way you wrote them out, though, indicates that they could be something different. Maybe isotopes? In this case the 1 and 2 are indicative of the amount of neutrons that the atom has.
Answer:
Option D) Compound B may have a lower molecular weight.
Explanation:
Compound A and B are standing at the same temperature yet compound A is evaporating more slowly than compound B.
This simply indicates that compound B have a lower molecular weight than compound A.
This can further be seen when gasoline and kerosene are placed under same temperature. The gasoline will evaporate faster than kerosene because the molecular weight of the gasoline is low when compared to that of the kerosene.
Answer
6.9 x 10¹²Hz
Explanation:
Given parameters:
Wavelength of the wave = 4.35 x 10⁻⁵m
Unknown:
Frequency of the wave = ?
Solution:
The speed of a wave is related to the wavelength and frequency using the expression below;
C = Fλ
C is the speed of light = 3 x 10⁸m/s
F is the frequency
λ is the wavelength
Insert the given parameters and solve;
3 x 10⁸ = F x 4.35 x 10⁻⁵
F = 
= 6.9 x 10¹²Hz
