Albert einstein determined this equation: energy (in joules) of a photon
is equal to planck's constant times the frequency of the light:
erhof
frequency (f) has units of 1/sec (which is a hertz, or hz)
planck's constant (h) = 6.626 x 10-34 j·sec
a) if the frequency of a red spectrum line is at 1.60 x 1014 hz, how
much energy does each photon of this light have?

When undergoing chemical reactions where does the reactant combine to the enzyme?

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
