WebAP® CHEMISTRY 2010 SCORING GUIDELINES Question 2 (continued) (c) Assume that the specific heat capacity of the calorimeter is negligible and that the specific heat capacity of the solution of urea and water is 4.2 J g −1 °C 1 throughout the experiment. (i) Calculate the heat of dissolution of the urea in joules. WebApr 12, 2024 · This is the value for energy of a single photon, and for ‘k’ no of photons, it would be: E = (k x 2 x 10²⁵)/λ. The value of E is calculated only when wavelength, λ is given in meters. If λ is given in any other unit let’s say in Angstrom, simply, we can convert 1 Angstrom to meters (1 Angstrom = 10⁻¹⁰m) where h is the Planck ...

WebThe value for carbohydrate energy in chocolate is an extreme example - the factors range from 5.56 kJ/g (1.33 kcal/g) to 17 kJ/g (4.0 kcal/g). For most individual foods that are major sources of energy in the diet, use of a specific rather than a general factor results in differences that range from -6 to +3 percent.
