#4 menSafety Information:5. Excess hydrochloric acid may be present at the conclusion of the reaction. Take appropriateprecautions.6. Hydrochloric acid is corrosive. External contact can cause severe burns. If contact does occur, washthe area immediately with water for 15 minutes and notify your teacher. Contact with the eyes cancause permanent damage. If contact with the eyes occurs, use the eyewash station for 15 minutesand call an ambulance.7. Always wear appropriate goggles and aprons when handling this acid.8. After reviewing your procedure, the instructor will discuss any safety precautions that are specificto your experiment.Questions:4. What volume of 3.00M hydrochloric acid would you need to react entirely with a 4.25g piece ofseashell that contained 87.0% calcium carbonate by mass?5. Calcium carbonate decomposes upon heating. What are the products of the decomposition reaction?6. Limestone is used in the construction of many buildings. Explain how acid rain affects limestone.Report: Please submit your lab online in PDF format. Ensure your lab report contains the followinginformation: Title, Procedure, Data, Calculations, Conclusion, and answers to Questions. In theconclusion, be sure to include which eggshell colour had more calcium carbonate, and indicate anypossible sources of error.

A cake requires 3 eggs, 4 cups of flour, 2 cups of sugar, 0.5 cups of oil, and 1 stick of butter. In the refrigerated pantry, a chef has the following available: 56 sticks of butter 60 eggs 12 gallons (192 cups) of oil 56 cups of flour 41 cups of sugar Select the four excess reagents. Do not select the limiting reagent. butter flour eggs sugar oil
£ Note: You may assume you have an excess of either reactant if the reaction requires more than one of those molecules to form the product. In the drawing area below, draw the skeletal ("line") structure of the missing organic product Y.

CONCLUSIONS: In general, the boiling points of compounds increase down a group in the periodic table. The melting points and boiling points for the hydrogen compounds of group 6A elements are in the table below. Melting Point (°C) Boiling Point (°C) H₂O 0.0 100.0 H₂S -82.0 -60.0 H₂Se -65.7 -41.2 H₂Te -49.0 -2.2 Use your understanding of chemistry to propose an explanation for the anomaly in the trend for the hydrogen compounds of group 6A elements shown in the table.
