Resting energy expenditure, abbreviated as REE, is the amount of energy, usually expressed in kcal (food calories), required for a 24-hour period by the body during resting conditions.It is closely related to, but not identical to, basal metabolic rate.esting energy expenditure, abbreviated as REE, is the amount of energy, usually expressed in kcal (food calories), required for a 24-hour period by the body during resting conditions.
Coefficients in a chemical equation represent the number of units of the formula immediately following the coefficient that are involved in the balanced equation for the react â¦ ion.1 person found this useful. Answered.oefficients are placed in front of the chemical formulas when balancing a chemical equation. Never change the subscripts in a formula in order to balance an equation.
Calculation of Chemical Composition. The calculation of the chemical composition is straight-forward. The molecular weight from the empirical formula divided by the sums of the atomic weights of each element to yield the percentage of each element. This is done for each element in the empirical formula and tabulated as the chemical composition. Please note the sort order is based on the electro-negativity of the element. Additional information provided is the chemical composition expressed as the % oxide of the element.
