Elements, Compounds & Mixtures- Day 1 2013

  1. 1. Name Date PeriodElements, Compounds and Mixtures (IR Pgs. 67-80, Text pgs. 134-147)Elements are pure substances made of only one kind of atom. As we have learned, atoms are tinystructures found in all matter. Most substances contain many different atoms. It is how those atomsare arranged that determine whether you have an element, a compound or a mixture.ELEMENT COMPOUND MIXTURES1. 1. 1.2. 2. 2.3. 3. 3.4. 4. 4.Particles look like: Particles look like: Particles look like:Examples: Example: Example: Salt Salad Coffee Aluminum can Heterogeneous HomogeneousYour Example: Your Example: Your Example:
  2. 2. Based on your diagrams and descriptions above, label the following illustrations as Elements,Compounds or Mixtures.A= B= C= D= E=Write the letters A, B, C, D or E from the pictures above that match the description. 1. _______ A pure compound made up of 3 elements 2. _______ Atoms of an Element 3. _______ A mixture of 3 elements, both of which are made of atoms 4. _______ Molecules of an element 5. _______ A pure compound made of 2 elements.Categorize as either Atom, Element, Molecule or Compound Item Classification Item Classification Sugar (C6H12O6) CO2 NaCl Water IronSolvent, Solute and Solution (pg. 144-145 in text)A solution is a mixture where all components blend together to look like one substance. A solution isa homogeneous mixture that appears to be a single substance. The solution is composed of particlesof two or more substances that are distributed evenly among each other and have the sameappearance and properties throughout. Coffee, Hot Chocolate, Gatorade, Brass, Our Atmosphereand Cleaning Fluids are all solutions.In solutions the SOLUTE is the substance that is being dissolved and usually is the smaller quantity in themixture. The SOLVENT is the substance doing the dissolving and is usually the larger quantity in themixture.How do you IDENTIFY the solvent or solute in a Homogeneous mixture/solution? Solute = Solvent = Solution =How are a Homogeneous and Heterogeneous Mixture different?
  3. 3. Give some examples in various states: (pgs. 144-145)States Example in the book Your exampleGas in gasGas in liquidLiquid in liquidSolid in liquidSolid in solidSaturation LevelsHave you ever put sugar into lemonade and seen the grains of sugar sink to the bottom and not dissolve? This isbecause the lemonade is supersaturated. In other words, there is not enough water(solvent) to completelydissolve the sugar (solute). Temperature and Pressure can affect saturation levels. Solutions can either be:Saturation Level What does this mean? What does this look like? (color)UnsaturatedSaturatedSupersaturatedChoose one correct answer for each:1. Fundamental substances that cannot be broken down chemically into simpler substances are____? A. Elements B. Ions C. Bonds D. electrons2. Which of the following processes can break down a compound? A. Dissolving & B. Distilling at the boiling C. Using a magnet to D. Applying an filtering points of the compound’s attract the metallic electric current components components3. When a solid copper block is heated at one end, the entire block is eventually heated. By what process isthe heat transferred? A. conduction B. convection C. Refraction D. Radiation4. If the molecules of a substance are locked in place, the substance is most likely a(n) A. Element. B. Compound. C. Gas. D. Solid.5. Which of the following occurs when a liquid is boiled? A. Its molecules break B. It undergoes a C. It breaks down D. Its molecules apart from each chemical reaction. into it elements. lock into place other
  4. 4. 6. What kind of change is needed to break down a compound? A. Physical B. Distillation C. Chemical D. Evaporation7. An element that conducts thermal energy well and is easily shaped is a A. metal B. nonmetal C. metalloid D. none of these8. Which of the following substances can be separated into simpler substances only by chemical means? A. Na B. Salt water C. Water D. Gold9. A(n) _______________ has a definite ratio of components A. element B. solute C. solvent D. compound10. The ________________ is the substance that dissolves to form a solution. A. solvent B. solute C. metal D. metalloid11. Elements with the same # of protons but different amount of neutrons in the nucleus are called A. Ions B. Valence C. Metals D. Isotopes12. According to the periodic table, which elements form the compound C 6H12O6? A. Carbon, B. Calcium, Helium C. Chromium and D. Carbon, Helium Hydrogen & and Oxygen Oxygen and Oxygen Oxygen13. Both Carbon Monoxide (CO) and Carbon Dioxide (CO 2) are made of Carbon and Oxygen, but they arenot the same compound. Explain why these compounds differ from each other.14. When nail polish is dissolved in acetone, which substance is the solute and which is the solvent? Why?15. In our classroom atmosphere about 78% is nitrogen and 22% is oxygen. Which gas is the solute and which isthe solvent?16. Which makes up most of the mass of living things?A. salts B. carbon C. air D. water17. Which element is the MOST important to living organisms on Earth?A. carbon B. nitrogen C. phosphorus D. hydrogen18. Chemical reactions usually release or absorb------?A. excess atoms. B. ions. C. heat D. atoms of carbon.
