# Honors Chemistry - Semester 1 Exam Study Guide 24-25 The exam will consist of 100 grade-style questions. The following documents will be provided as resources: * Periodic Table with States of Matter * Naming, Ions, and Formulas Sheet (orange paper) * Activity Series and Solubilities of Ionic Compounds (yellow paper) * Conversion Factors and Metric Prefixes (pink paper) * AP Chemistry Equations and Constants Sheet (white paper) Students will need to show their work for all math problems. The following is an approximate breakdown of the topics covered in the exam: | Topic | Estimated # of Questions | |---------------------------|-------------------------| | Matter and Separation | | | Measurement, Significant Figures, and Density | | | Unit Conversion and the Metric System | | | Atomic Mass and Fundamental Laws | | | Molar Relationships | | | Elements and Compounds | | | Solutions and Molarity | | | Chemical Reactions | | | Labs and Interpreting Experimental Data | | | Stoichiometry | | **Unit 1: Matter and Lab Safety** **Lab Skills** * Apply lab safety guidelines. * Describe safety protocols and explain their reasons. * Classify appropriate and inappropriate lab clothing and accessories. * Describe proper handling and disposal of chemicals. * Explain proper first aid responses. **Matter** * Classify matter as element, compound, homogeneous mixture, or heterogeneous mixture. * Identify properties as physical, chemical, or both. * Compare and contrast physical and chemical changes. * Describe indications of chemical changes. * Identify differences between solid, liquid, and gaseous phases. * Identify processes by which substances change phases (endothermic/exothermic). **Separation Techniques** * Determine processes to separate different types of matter. * Identify unknown substances using observations. * Classify substances as soluble or insoluble. * Predict precipitate formation. * Distinguish between flammable and non-flammable gases. * Explain how to separate substances with different properties. * Use observations from demonstrations to predict new substances. * Describe separation techniques like filtration and distillation. **Unit 2: Measurement** **Measurement and Significant Figures** * Identify graduated and estimated places on measuring devices. * Compare standard and non-standard measuring devices. * Measure mass, volume, length, temperature, and pressure correctly. * Apply significant figure rules and explain the significance of zeros.
