Review Booklet: Sec 3 Applied 1. 2. Fill in the following table Carbon dioxide Test Name Lime water Reaction to the test Turns cloudy Hydrogen Flaming Splint pops Oxygen Glowing Splint Relights the splint Color in the test that will react with the liquids in the left column Red Litmus Saltwater Distilled water Alcohol Acid Base 3. reacts Blue Litmus Cobalt chloride reacts reacts Conductivity reacts reacts reacts reacts reacts reacts What substance is each example describing? Underline the characteristic property that enabled you to identify the substance. a. I am colorless, I am tasteless and I have a density of !g/ml Distilled water because it has a density of 1 b. I turn red litmus paper blue, I turn cobalt paper pink and I conduct electricity Base because it turns red litmus blue c. I have a mass of 6 g, I cause a pop with a flaming splint and I have no scent Hydrogen because it pops using the flaming splint test 4. What test allows you to differentiate between saltwater and distilled water? Electrical Conductivity 5. What test allows you to identify if water is present in a liquid? Cobalt Chloride 6. Use the table to determine the density of a rock Mass Volume of water in cylinder Volume of water + rock 19 g 200mL 222mL Mass of rock: 19g Volume of rock : 222ml-200ml 22ml Density = 19g/22ml = 0.86g/mL 7. Use the table to determine the density of apple juice Volume Mass of graduated cylinder Mass of graduated cylinder+ juice 96 ml 60g 110g Mass of apple juice: 110g-60g 50 g Volume of apple juice: 96 mL Density = 50g/96ml = 0.52 g/ml 8. You have an unknown liquid you think is vinegar. You know the density of vinegar is 1.5g/mL. You also know the mass of the unknown is 5.5. g and its volume is 2 mL. Explain if your unknown liquid is vinegar. Density : 5.5/2 2.75g/ml Therefore the unknown is not vinegar because the densities do not match. 9. Balance the following equations and determine which type of chemical reactions they are. a) S+ O2 SO2 Type of chemical reaction: oxydation b) 2KClO3 Type of chemical reaction: 2KCl + 3O2 decomposition c) H2 + 2Cl 2HCl Type of chemical reaction: synthesis d) CH4 + 2O2 Type of chemical reaction: CO2 + Oxydation 2H2O 10. Indicate whether each pure substance below is a compound or an element a. Br2 Compound b. NaCl Compound c. Mg Element d. HI Compound e. H2O Compound 11. Name the signs of a chemical reaction 1. Creation of a gas 2. Absorption or release of energy 3. Emits light 4. Changes color 5. Forms a precipitate 12. Name all type of nutrients. 1. Carbohydrates 2. Lipids 3. Proteins 4. Minerals 5. Vitamins 6. Water 7. Fiber 13. What are three areas that filter the air we breathe? Nasal cavity, trachea, bronchi 14. What are the two muscles responsible for respiration? Intercostal muscles, Diaphragm 15. Fill in the following chart Diaphragm Ribs Lungs Air 16. Inhale Contracts and moves down Move up and out Increase in volume Flows in Exhale Relaxes and moves up Move down and in Decrease in volume Flows out Explain why air enters our lungs when we inhale Air enters our lungs because as the diaphragm lowers, the volume of the lungs increases. This leads to the decrease in the pressure of the lungs and the air automatically flows into the lungs to balance the pressure. 17. Label the following diagram of the respiratory system 1. Nasal Cavity 2. Mouth 3. Larynx 4. Right Lung 5. Right Bronchi 6. Diaphragm 7. Pharynx 8. Trachea 9. Left Bronchi 10. Bronchioles 11. Alveoli 18. Label the following diagram of the digestive system. 1. Mouth 2. Pharynx 3. Liver 4. Stomach 5. Gall bladder 6. Stomach 7. Large intestine 8. Small Intestine 9. Rectum 10. Appendix 11. Rectum 12. Anus 19 Fill in the following nutrient table Examples Carbohydrate Bread, Potatoes 1st breakdown Location Mouth Gland used Gland used Simplest form Recommen ded dose Energy value of 1 g Salivary glands 2nd Breakdown Location Small Intestine Intestinal glands Glucose 340g 17kJ/g Proteins Meat, eggs Stomach Gastric glands Small Intestine Intestinal glands Amino acids 2g / kg 17kJ/g Lipids Butter, Oil Small Intestine Intestinal Glands Small Intestine Intestinal glands Glycerol Fatty acids 85 g 37kJ/g 20.
