A beam of light has a wavelength of 506 nanometers. What is the frequency of the light? What color is the light

Beam Light wavelength = 506 nanometer Frequency of light = F The color of light = L To fine the electromagnetic field: => S = wavelength x Frequency Frequency = (3 x 10^8) / (5.06 x 10^ -7) F = 5.96 x 10^14 Hz According to the visible light spectrum, wavelength from 495 to 570 is equals to the color of green. Since the given wavelength is 506, thus, the color of light is green.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
