Answer:
Infrared
Explanation:
To calculate the wavelength if the electromagnetic radiation, we must use the following formula:
c = f × λ
where c is the speed of the wave (in this case it's the speed of light, which is 3 × 
m/s) , f is the frequency and λ is the wavelength.
Using this formula, all we have to do is plug in our values and rearrange for the answer:
c = f × λ
3 × = 5.00 x 
Hz × λ
λ = 3 × /5.00 x
λ = 6.00 × 
m = 6.00 ×
nm
Now that we know the wavelength we can figure out which kind of electromagnetic radiation this is.
6.00 × nm falls in the range of infrared radiation. We know this either from memorizing the values of the wavelengths or looking up a reference.
The phase is Waning Crescent phase.

19.11 g of MgSO₄ is placed into 100.0 mL of water. The water's temperature increases by 6.70°C. Calculate ∆H, in kJ/mol, for the dissolution of MgSO₄. (The specific heat of water is 4.184 J/g･°C and the density of the water is 1.00 g/mL). You can assume that the specific heat of the solution is the same as that of water.
