586729 luster - PS1-2PS1-5_NaMgRxns PROD 2 Paper 556268 Shared Stimulus - Shared Stimulus Read the information. Use the information to answer the questions. Sodium and Magnesium Reactions To begin a study of chemical reactions, a teacher shows the students in a chemistry class two videos. Each video shows the reaction of a different metal. Students first observe the reaction of the metal sodium (Na) with water (H 2 O). In the video, 500 mg of sodium from an oil-filled container is placed into a beaker of water at room temperature (20 ). The sodium quickly bursts into flames and explodes with a loud popping sound. The reaction equation is 2Na + 2H 2 O 2NaOH + H 2. In the next video, the students observe the reaction of the metal magnesium (Mg) with water. In the video, 500 mg of magnesium is placed into a beaker of water at room temperature. The video shows that it takes several hours for bubbles to form on the magnesium. The bubbles that form are hydrogen (H 2 ) gas, according to the reaction equation Mg + 2H 2 O Mg(OH) 2 + H 2. The students wonder, What causes the reactivity of sodium and magnesium to be so different? They decide to use The Periodic Table of the Elements and gather more information to answer this question. 556270 Shared Stimulus - Shared Stimulus lues from Sodium and Magnesium ompounds Students research sodium and magnesium compounds to gain more data to answer their question. They learn that sodium readily forms the following compounds: sodium chloride (Nal) sodium fluoride (NaF) sodium oxide (Na 2 O) sodium sulfide (Na 2 S) They also learn that magnesium forms compounds with some of the same nonmetal elements that sodium does. The following compounds form with magnesium: magnesium chloride (Mgl 2 ) magnesium fluoride (MgF 2 ) magnesium oxide (MgO) magnesium sulfide (MgS) 2
y examining the positions of these elements on The Periodic Table of the Elements (see reference sheet), the students see some patterns in the way sodium and magnesium react with nonmetals. 556272 Shared Stimulus - Shared Stimulus Effect of Temperature on Reaction Rate The students wondered how the speed of the magnesium and water reaction could be increased. They decide to investigate whether adding heat to the reaction will affect the reaction rate. They place 50 mg of magnesium into a test tube with 10 ml of water. They heat the test tube with a flame. Within seconds, the magnesium begins to bubble rapidly, producing hydrogen gas. The students compare the results of the magnesium and water reaction at 25 to the results of the reaction with heat added. They draw a graph to represent their hypothesis about the rate of product formation for the reaction at different temperatures. Product vs. Time Volume of H 2 Time high temperature low temperature 3
557640 hoice - PS-PS_NaMgRxns_SR1_Tab 1_conserv 1 The students study the equations for the reactions of Na and Mg with H 2 O to explain the outcomes of the reactions. Which observation would provide the best evidence that matter is conserved in the reaction of Na and H 2 O? The number of atoms of Na is the same on both sides of the equation. The number of electrons and protons in Na is equal to the number of electrons and protons in H and O. The mass of Na and H 2 O that reacts is greater than the mass of H 2 produced. D The mass of NaOH produced is equal to the mass of H 2 O that is changed into steam as the Na explodes into flames. 557636 hoice - PSPS_NaMgRxns_SR1_Tab 1_1bonds 2 The students consider the bonds that form in the reactions of Na and Mg with H 2 O.

D Na and Mg both form covalent bonds. 4

They want to show the outer electron states of both elements and explain why this affects the reactivity of both elements. Part Which model shows the number of valence electrons for Na and Mg?

586735 luster - LS2-5ESS2-6_ycleTree PROD 2 PPER 557214 Shared Stimulus - Shared Stimulus Read the information. Use the information to answer the questions. Trees in Urban Parks The altimore ity Parks and Recreation Department plans to remove a group of trees in an urban park to expand a parking lot. efore the trees can be removed a study needs to be completed to determine the possible effect of tree removal on the park s ecosystem. Trees in urban parks in altimore store about 43 tons of carbon per acre, and 1.2 tons of carbon per acre is lost each year from the removal of trees. tree scientist calculated the amount of carbon stored by the trees scheduled to be removed in the park. First, the scientist measured the circumference of the trunk of five trees. Then, the scientist used a tool called a clinometer to calculate the height of each tree. The scientist entered these measurements into a formula to estimate the amount of carbon stored in each tree. The results are shown in the table. arbon Stored in Urban Trees Tree Number ircumference (m) Tree Height (m) Estimated arbon Stored (kg) 1 0.25 10 15 2 1.25 40 539 3 0.50 16 43 4 0.75 18 95 5 1.00 36 315 Total 1007 7
The scientist also recorded observations from around the park. For example, there were leaves and small branches on the ground beneath the trees. The scientist used the data and observations from the urban trees to make a partial model of the carbon cycle. W O 2 O 2 O 2 X Dead leaves Roots Y Soil 557385 Shared Stimulus - Shared Stimulus Trees and the Global arbon ycle The data show the total carbon stored in trees, while the model shows how carbon moves through the carbon cycle. The scientist wants to compare the locally collected data and model with global carbon data and carbon cycle models to predict the potential impact of tree removal from the park. 8
The total amount of carbon stored in forests changes each year as carbon moves through the hydrosphere, atmosphere, geosphere, and biosphere. First, the scientist gathered historical data from 1990 1997. Global carbon () estimates are shown in the tables. Global arbon Stored Each Year from 1990 1999 Location arbon Stored (gigatons* of per year) atmosphere 3.2 ocean forests total 2.2 2.5 7.9 *1 gigaton = 1 billion tons Global arbon Lost Each Year from 1990 1999 Process arbon Loss (gigatons* of per year) fossil fuel burning 6.5 deforestation total 1.5 8.0 *1 gigaton = 1 billion tons fter 1999, fossil fuel burning increased and deforestation decreased. The scientist estimated that compared to the time frame of 1990 1999, during 2000 2007 the atmosphere stored 0.9 more gigatons of carbon, the oceans stored 0.1 more gigatons of carbon, and the forests stored 0.1 fewer gigatons of carbon. 9
564397 hoice - LSESS_ycleTree_SR1_Tab1_data&model 7 Which statement describes a relationship shown between the arbon Stored in Urban Trees data and the partial model of the carbon cycle? The amount of carbon from the atmosphere stored by trees in the urban park is based on the size of the trunk and tree height. The amount of carbon stored by trees in the urban park is small because the trees constantly release carbon to the atmosphere. arbon is stored and lost in equal amounts because the dead leaves release the carbon originally stored by trees. D arbon is stored in the trees because the carbon from the soil is used to build the trunk of the tree. 565034 hoice - LSESS_ycleTree_RSR1_Tab1_565026 8 Which equation shows the process in the model by which carbon dioxide is stored in the tree? energy + 6O 2 6 H 12 O 6 + H 2 O 6 H 12 O 6 + 6H 2 O 6O 2 + 6O 2 6O 2 + 6H 2 O 6 H 12 O 6 + 6O 2 D 6O 2 + 6 H 12 O 6 6O 2 + 6H 2 O + energy 10
565043 hoice - LSESS_ycleTree_RSR1_Tab1_565036 9 Which statement best describes a carbon exchange process that occurs in the carbon cycle model? arbon is stored in the biosphere in part Y and moves to the atmosphere in part W. arbon is stored in the biosphere in part W and moves to the geosphere in part Y. arbon moves from the biosphere to the atmosphere in parts W and Y. D arbon moves from the biosphere to the geosphere in parts X and Y. 565070 hoice - LSESS_ycleTree_SR1_Tab1_modelimprove 10 Which statement best describes how the arbon Stored in Urban Trees data table should be improved to better support the model and represent the cycling of carbon? It should include the amount of carbon lost to the atmosphere due to respiration by the trees. It should include the amount of carbon stored in the soil due to photosynthesis by the trees. It should include the amount of oxygen released by the trees due to photosynthesis. D It should include the amount of oxygen consumed by the trees due to respiration. 11

Then, choose the graph that represents the amount of global carbon stored in each location from 2000 2007.
