WebbThe 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. WebbMechanical Energy: It is the sum total of potential energy and kinetic energy which is the energy associated with the motion & position of any object. Therefore, the formula of … WebbThe energy of the electron is given by this equation: E = − k Z 2 n 2 The atomic number, Z, of hydrogen is 1; k = 2.179 × 10 –18 J; and the electron is characterized by an n value of 3. Thus, E = − ( 2.179 × 10 −18 J) × ( 1) 2 ( 3) 2 = −2.421 × 10 −19 J Check Your Learning The electron in Figure 6.15 is promoted even further to an orbit with n = 6. sims 2 rented space alesso omen
