The talus bone of the foot receives the weight of the body from the tibia. The talus bone then distributes this weight toward the ground in two directions: one-half of the body weight is passed in a posterior direction and one-half of the weight is passed in an anterior direction. Describe the arrangement of the tarsal and metatarsal bones that are involved in both the posterior and anterior distribution of body weight.
Cont. ch 9 To measure the heat flow at a constant volume ( ΔE ¿ Heat capacity (c): is the amount of heat that is necessary in order to raise the temperature of an object or the substance of a given amount q C= q=C ×ΔT ΔT Specific heat capacity (c): is the amount of heat that is required in order to raise the temperature of 1 g of a substance by 1 degree C. q= (Mass of substance) x (Specific Heat) x ΔT Molar Heat Capacity (Cm): the amount of heat that is necessary for the temperature to rise, 1 mol of a substance by 1 degree C q= Cm x moles of substance x ΔT Conversions: 1 Kcal = 4.184 Kj 1 atm = 760 torr 101.325 J = 1 L ` atm 1 kcal = 1 cal Hess’s Law: is the overall enthalpy change of a reaction that is equal to the sum of the enthalpy change for the individual steps in the reaction Δ H Harber Process: is when you have to find 2 H (g)+N (g)→N H g ) 0 Ex: 2 2 2 4 Δ H =95.4kJ N H (g)+H g →2 N H (g) Δ H =−187.6kJ 2 3 3H (g)+N g →2 N H (g) Δ H =−92.2 2 2 3 0 Standard Heat of Formation ( Δ H ¿F : Enthalpy change for the formation of 1 mole of a su
