Anabolism - Uses energy to construct components of cells. Catabolism - Breaks down organic matter, for example, to harvest energy. Nutrient Density - A measure of the nutrient a food provides compared to its energy content. Trace Minerals - Needed only in tiny amounts. These minerals participate in most chemical reactions in the body. These include iron, zinc, iodine, copper, manganese. Protein Complementation - The act of consuming a variety of plant products to provide all the necessary...

Chem Exam: Types of Calculation Questions & Answers 100% Verified Calorimetry Calculations: 1. 2.50 kJ of energy changes the temperature of a sample of lead by 8.52 degrees C. What is the mass of the sample? - ANS-Q = mcΔT m=Qc/Δt m = 2500/0.13(8.52) = 2.3×103 g 2. 950.3 J of energy is removed from 28.5 g of water at 80.3 degrees C. What is the final temperature? - ANS-Q = mcΔT −950.3 = 28.5(4.18)(T2 − 80.3) T2 = −950.3/(28.5)(4.18) + 80.3 = 72.3O C 3. A 30.56 g sample...
