I believe the answer is burning a candle
Calcium Chloride is the salt that is effective for melting ice on roads
The equation that relates both energy and wavelength is:

where e is the energy and lambda is the wavelength.
Therefore, as we can see from this equation, the energy of an electromagnetic wave is inversely related to the wavelength of the electromagnetic wave.
Answer:
To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol).
Answer:
iron atoms
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number
of particles.
contains= 2 atoms of iron
contains=
atoms of iron
thus 0.32 moles of
contains=
atoms of iron
Thus the sample would have
iron atoms.
