Please answer question 17 Part A
Crime scene investigators keep a wide variety of compounds on hand to help with identifying unknown substances they find in the course of their duties. One such investigator, while reorganizing their shelves, has mixed up several small vials and is unsure about the identity of a certain powder. Elemental analysis of the compound reveals that it is 67.31 % carbon, 6.978% hydrogen, 4.617% nitrogen, and 21.10% oxygen by mass. Which of the compounds could the powder be? C17H19NO3C17H19NO3 = morphine, analgesic C17H21NO4C17H21NO4 = cocaine, illicit drug C7H5N3O6C7H5N3O6 = 2,4,6-trinitrotoluene (TNT), commonly used explosive C10H15NC10H15N = methamphetamine, stimulant C4H5N2OC4H5N2O = caffeine, stimulant C11H15NO2C11H15NO2 = 3,4-methylenedioxymethamphetamine (MDMA), illicit drug C21H23NO5C21H23NO5 = heroin, illicit drug C3H6NO3C3H6NO3 = hexamethylene triperoxide diamine (HMTD), commonly used explosive

write mixture if it is corresponds with mixture and compound if it is corresponds with compound. -atoms of different elements chemically combined together in a fixed ratio -combination of two or more substances-elements or compounds -ingredients that are physically mixed but chemically separate -substances combined together in varying ratio -represented by a chemical formula -can be separated into simpler substances by chemical reaction -can be separated into simpler substances by physical means -have its characteristic chemical and physical properties that are distinct from its components -reflects the chemical and physical properties of its components -can be homogeneous or heterogeneous
A substance composed of 2 or more elements in a fixed, definite proportion is considered a homogeneous mixture. a heterogeneous mixture. a molecular compound an alloy. a solution.
Mixture is a combination of two or more substances that are not chemically combined. The substances are formed together but no new substance is formed. A mixture can be of any form. It may be solid, liquid or in gaseous form. Mixtures can be classified according to their appearance. Uniform mixtures or Homogenous Mixtures have substances that cannot be recognized because solutes completely dissolve in the solvent while Nonuniform or heterogeneous mixtures have components which can be identified easily. EXPERIMENT: Forming Mixtures A. Materials: Three glasses, water, teaspoon, flour, food color/soy sauce, cooking oil, pebbles/small stones B. Procedure: 1. Half-fill the four glasses with water. 2. Put the food color/soy sauce in one glass. Stir. Label it as "Set A. 3. Put a teaspoon of flour in the second glass. Stir. Label it as "Set B". 4. Put a teaspoon of cooking oil in the third glass. Stir. Label it as "Set C". 5. Put the pebbles/small stones and the flour in a plate or petri dish…
