<p>WRITING PROMPTS - CHEMISTRY</p><p> Respond to the following statement: "All substances are either soluble or insoluble. If I put some stuff in water and nothing appears to happen, then it must be completely insoluble. A solubility chart can tell me this information and it is always correct." </p><p> Explain how to calculate the pH of a base solution. </p><p> The molecules BF3 and NH3 both have covalent bonds. Explain why BF3 is described as a trigonal planer shape while NH3 is described as a trigonal pyramidal shape. </p><p> Write a paragraph explaining the differences between a real gas and an ideal gas. Use the ideas from the kinetic molecular theory, and give examples of when an ideal gas may be described as a real gas. </p><p> After reading Passage 1, “The Science of Chemistry,” do you generally think of chemicals in negative terms as described in paragraph three or do you think of them with a more positive point of view as described in paragraph four? Why? Please explain your point of view with a paragraph. Use the “Writing Across the Curriculum: template to help organize your thoughts before beginning your paragraph. </p><p> Explain how the structures of the four types of organic molecules relate to function.</p><p> Explain the difference between quantitative and qualitative data. In your exploration, give examples of the two types of data.  A student mixed two substances together and concluded that a chemical reaction had taken place. Explain how the student was able to conclude that a chemical reaction occurred. In your explanation, be sure to include</p><p>• evidence that would support the student’s conclusion</p><p>Compare the properties of oil to the properties of the elements in oil. In your comparison, be sure to include • the properties of oil • the properties of the elements in oil • the motion of the molecules in oil, carbon, and hydrogen</p><p> Explain how heat energy affects a substance. In your explanation, be sure to include</p><p>• the temperatures at which a substance changes states of matter • After the beaker containing Mixture 4 was sealed, the iron filings changed color. Compare the mass of the mixture in the sealed beaker to the masses</p><p> of the iron filings and water before they were mixed. In your comparison, be sure to include • the law of conservation of matter • evidence from the data table</p>
