Visible light falls into wavelength ranges of 400-700 nm, for which 

. 

The energy and wavelength of light are related by the equation

where 

 is energy in Joules, 

 is Planck's constant (

), 

 is the speed of light (

), and 

 is the wavelength in m.

If a visible light photon has a wavelength of 452.2 nm, what is the energy of the photon (in J)?

Calculate the molecular weight of phosphorus if 2.3437 grams are dissolved in 50.000 grams of para-dibromobenzene and the solution freezes at 81.35 degrees Celsius. What is the molecular formula for phosphorus?

Beano contains an enzyme that breaks down polysaccharides into smaller, more digestible sugars, which diminishes the intestinal gas formation that can occur after eating foods such as vegetables and beans. (20.1, 20.2, 20.5) a. The label says “contains alpha-galactosidase.” What class of enzyme is this? b. What is the substrate for the enzyme? c. The directions indicate you should not cook with or heat Beano. Why?
