Q1 MC 1 Student uses a table of solubility rules to identify which of a set of chemicals is soluble. Q2 MC 2 Student identifies which pair of substances can be separated through filtration. Q3 MC 3 Student analyzes an incomplete chemical reaction involving precipitates from aqueous solutions to identify the missing compound. Ⓡ CHEM.10E Distinguish between types of solutions such as electrolytes and nonelectrolytes and unsaturated, saturated, and supersaturated solutions. Q1 MC 1 Student identifies the definition of one of the terms from the standard. Q2 MC 2 Student uses a solubility curve to determine either the quantity of a substance that can be dissolved in a given amount of water at a given temperature, or the temperature at which a given quantity of a substance can be dissolved in a given amount of water. Q3 MC 2 Student uses information about an investigation and terminology from the standard to explain an observation from the investigation. Ⓡ CHEM.10F Investigate factors that influence solubilities and rates of dissolution such as temperature, agitation, and surface area. Q1 MC 1 Student identifies which of a list of methods would speed or slow the rate of dissolution of a substance. Q2 MC 2 Student uses a graph showing solubility curves to identify the substance whose solubility has a specified property or rate. Q3 MC 3 Student analyzes a graph of solubility curves and information from an experiment to determine the identity of an unknown substance. Ⓢ CHEM.10D Use molarity to calculate the dilutions of solutions. Q1 GR 2 Student calculates the quantity or molarity of a substance necessary for a specified dilution. Q2 MC 3 Student analyzes information about possible dilutions to determine which one was calculated correctly or incorrectly. Ⓢ CHEM.10A Describe the unique role of water in chemical and biological systems. Q1 MC 2 Student identifies an example of a unique property of water that contributes to its role in chemical and/or biological systems. Q2 MC 1 Student identifies the property of water that enables it to perform specified functions. Ⓡ CHEM.8B Use the mole concept to calculate the number of atoms, ions, or molecules in a sample of material. Q1 MC 4 Student evaluates a calculation involving the concepts in the standard to determine why the
