According to USDA Organic, What are the standards for how cosmetics and personal care products are certified? Are there specific grades or amounts of certified ingredients required to receive the certification?

When you add starch to the solution, present of a black color indicates:     the solution contains KI     the solution contains I2     the solution contains S4O62-

Question #11

C) Complete Oxidation or Burning of Organic Compounds 5) Propane, C,Hg, burns in air. 6) Acetone (nail polish remover), CH3COCH3, is completely oxidized.

the oxidation of glucose and palmitic acid yields 15.64 kJ/g and 38.90 kJ/g, respectively. Calculate these values in terms of kJ/mol and kJ per carbon atom oxidized for both glucose and palmitic acid.

It is part of the plant cell wall. Provides rigidity to cells and tissues: Maltose Starch aminopectin Cellulose

Chapter 8- Carbohydrates (pages 221 - 223) 1. What are carbohydrates and what are the three elements that make them up? What is the general formula of carbohydrates? 2. One of the simplest carbohydrate is glyceraldehyde. Glyceraldehyde (number of carbons) carbon sugar. is a 3. Draw the structure of D-glyceraldehyde (Fig. 8-1, page 222) in the space below. 4. Monosaccharides can be aldoses or ketoses, depending on the position of the carbonyl group. Describe aldoses and ketoses: a. Aldoses: H b. Ketoses*: *IMPORTANT NOTE: The most common ketoses have the ketone function at carbon 2. 5. Circle the carbonyl group in the structures below and specify if the structures correspond to an aldose or ketoses. CH₂OH H-C-OH CH₂OH C=O 1 CH₂OH

describe the conversion of cellulose to carbon materials.
