Answer:

B. The western coast of the united states

Explanation:

I'm not sure if its correct but its pretty simple to understand, if you look at the arrows red represents heat, and blue represents cold, the red arrows (warm climate) is at the left more towards the U.S, therefore looking at the guide of North West South and East, it is at the western coast of the u.s

How is the wavelength of an electromagnetic wave related to the energy of the wave?

Sauron [17]

The equation that relates both energy and wavelength is:

$e=\frac{h*c}{lambda}$

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.

How many iron atoms are in 0.32 mol of Fe2031? 3.9x 1023 jron atoms O 3.9 iron atoms O 6.02 x 1023 iron atoms 1.9 x 1023 iron at

Gennadij [26K]

Answer: $3.9\times 10^{23}$ iron atoms

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

$1 molecule of [tex]Fe_2O_3$ contains= 2 atoms of iron

$1 mole of [tex]Fe_2O_3$ contains= $2\times 6.023\times 10^{23}=12.05\times 10^{23}$ atoms of iron

thus 0.32 moles of $Fe_2O_3$ contains= $\frac{12.05\times 10^{23}}{1}\times 0.32=3.9\times 10^{23}$ atoms of iron

Thus the sample would have $3.9\times 10^{23}$ iron atoms.
